When a web request body is larger than the limit, the underlying host service only forwards the contents that are within the limit to WAF for inspection.
      • For Application Load Balancer and AppSync, the limit is fixed at 8 KB (8,192 bytes).
      • For CloudFront, API Gateway, Amazon Cognito, App Runner, and Verified Access, the default limit is 16 KB (16,384 bytes), and you can increase the limit for each resource type in the web ACL AssociationConfig, for additional processing fees.
      The options for oversize handling are the following:
      • CONTINUE - Inspect the available body contents normally, according to the rule inspection criteria.
      • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
      • NO_MATCH - Treat the web request as not matching the rule statement.
      You can combine the MATCH or NO_MATCH settings for oversize handling with your rule and web ACL action settings, so that you block any request whose body is over the limit.
      Default: CONTINUE

  • cookies

To require a match in the keys and in the values, use a logical AND statement to combine two match rules, one that inspects the keys and another that inspects the values.
      
    • oversize_handling
      Type: STRING
      Provider name: OversizeHandling
      Description: What WAF should do if the cookies of the request are more numerous or larger than WAF can inspect. WAF does not support inspecting the entire contents of request cookies when they exceed 8 KB (8192 bytes) or 200 total cookies.

  • ja3_fingerprint
    Type: STRUCT
    Provider name: JA3Fingerprint
    Description: Available for use with Amazon CloudFront distributions and Application Load Balancers. Match against the request’s JA3 fingerprint. The JA3 fingerprint is a 32-character hash derived from the TLS Client Hello of an incoming request. This fingerprint serves as a unique identifier for the client’s TLS configuration. WAF calculates and logs this fingerprint for each request that has enough TLS Client Hello information for the calculation. Almost all web requests include this information. You can use this choice only with a string match ByteMatchStatement with the PositionalConstraint set to EXACTLY. You can obtain the JA3 fingerprint for client requests from the web ACL logs. If WAF is able to calculate the fingerprint, it includes it in the logs. For information about the logging fields, see Log fields in the WAF Developer Guide.

    • invalid_fallback_behavior
      Type: STRING
      Provider name: InvalidFallbackBehavior
      Description: What WAF should do if it fails to completely parse the JSON body. The options are the following:
      • EVALUATE_AS_STRING - Inspect the body as plain text. WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
      • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
      • NO_MATCH - Treat the web request as not matching the rule statement.
      If you don’t provide this setting, WAF parses and evaluates the content only up to the first parsing failure that it encounters. WAF parsing doesn’t fully validate the input JSON string, so parsing can succeed even for invalid JSON. When parsing succeeds, WAF doesn’t apply the fallback behavior. For more information, see JSON body in the WAF Developer Guide.
      
    • match_pattern
      Type: STRUCT
      Provider name: MatchPattern

    Provider name: Name
    Description: The name of the rule. If you change the name of a Rule after you create it and you want the rule’s metric name to reflect the change, update the metric name in the rule’s VisibilityConfig settings. WAF doesn’t automatically update the metric name when you update the rule name.
    
  • override_action
    Type: STRUCT
    Provider name: OverrideAction
    Description: The action to use in the place of the action that results from the rule group evaluation. Set the override action to none to leave the result of the rule group alone. Set it to count to override the result to count only. You can only use this for rule statements that reference a rule group, like RuleGroupReferenceStatement and ManagedRuleGroupStatement. This option is usually set to none. It does not affect how the rules in the rule group are evaluated. If you want the rules in the rule group to only count matches, do not use this and instead use the rule action override option, with Count action, in your rule group reference statement settings.

  • rule_labels
    Type: UNORDERED_LIST_STRUCT
    Provider name: RuleLabels
    Description: Labels to apply to web requests that match the rule match statement. WAF applies fully qualified labels to matching web requests. A fully qualified label is the concatenation of a label namespace and a rule label. The rule’s rule group or web ACL defines the label namespace. Rules that run after this rule in the web ACL can match against these labels using a LabelMatchStatement. For each label, provide a case-sensitive string containing optional namespaces and a label name, according to the following guidelines:
    • Separate each component of the label with a colon.
    • Each namespace or name can have up to 128 characters.
    • You can specify up to 5 namespaces in a label.
    • Don’t use the following reserved words in your label specification: aws, waf, managed, rulegroup, webacl, regexpatternset, or ipset.
    For example, myLabelName or nameSpace1:nameSpace2:myLabelName.

        • body
          Type: STRUCT
          Provider name: Body
          Description: Inspect the request body as plain text. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. WAF does not support inspecting the entire contents of the web request body if the body exceeds the limit for the resource type. When a web request body is larger than the limit, the underlying host service only forwards the contents that are within the limit to WAF for inspection.

          • For Application Load Balancer and AppSync, the limit is fixed at 8 KB (8,192 bytes).
          • For CloudFront, API Gateway, Amazon Cognito, App Runner, and Verified Access, the default limit is 16 KB (16,384 bytes), and you can increase the limit for each resource type in the web ACL AssociationConfig, for additional processing fees.
          For information about how to handle oversized request bodies, see the Body object configuration.
          
          • oversize_handling
            Type: STRING
            Provider name: OversizeHandling
            Description: What WAF should do if the body is larger than WAF can inspect. WAF does not support inspecting the entire contents of the web request body if the body exceeds the limit for the resource type. When a web request body is larger than the limit, the underlying host service only forwards the contents that are within the limit to WAF for inspection.
            • For Application Load Balancer and AppSync, the limit is fixed at 8 KB (8,192 bytes).
            • For CloudFront, API Gateway, Amazon Cognito, App Runner, and Verified Access, the default limit is 16 KB (16,384 bytes), and you can increase the limit for each resource type in the web ACL AssociationConfig, for additional processing fees.
            The options for oversize handling are the following:
            • CONTINUE - Inspect the available body contents normally, according to the rule inspection criteria.
            • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
            • NO_MATCH - Treat the web request as not matching the rule statement.
            You can combine the MATCH or NO_MATCH settings for oversize handling with your rule and web ACL action settings, so that you block any request whose body is over the limit.
            Default: CONTINUE

          • match_scope
            Type: STRING
            Provider name: MatchScope
            Description: The parts of the cookies to inspect with the rule inspection criteria. If you specify ALL, WAF inspects both keys and values. All does not require a match to be found in the keys and a match to be found in the values. It requires a match to be found in the keys or the values or both. To require a match in the keys and in the values, use a logical AND statement to combine two match rules, one that inspects the keys and another that inspects the values.
            
          • oversize_handling
            Type: STRING
            Provider name: OversizeHandling

          Type: STRUCT
          Provider name: JA3Fingerprint
          Description: Available for use with Amazon CloudFront distributions and Application Load Balancers. Match against the request’s JA3 fingerprint. The JA3 fingerprint is a 32-character hash derived from the TLS Client Hello of an incoming request. This fingerprint serves as a unique identifier for the client’s TLS configuration. WAF calculates and logs this fingerprint for each request that has enough TLS Client Hello information for the calculation. Almost all web requests include this information. You can use this choice only with a string match ByteMatchStatement with the PositionalConstraint set to EXACTLY. You can obtain the JA3 fingerprint for client requests from the web ACL logs. If WAF is able to calculate the fingerprint, it includes it in the logs. For information about the logging fields, see Log fields in the WAF Developer Guide. Provide the JA3 fingerprint string from the logs in your string match statement specification, to match with any future requests that have the same TLS configuration.

        • json_body
          Type: STRUCT
          Provider name: JsonBody
          Description: Inspect the request body as JSON. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. WAF does not support inspecting the entire contents of the web request body if the body exceeds the limit for the resource type. When a web request body is larger than the limit, the underlying host service only forwards the contents that are within the limit to WAF for inspection.

          • For Application Load Balancer and AppSync, the limit is fixed at 8 KB (8,192 bytes).
          • For CloudFront, API Gateway, Amazon Cognito, App Runner, and Verified Access, the default limit is 16 KB (16,384 bytes), and you can increase the limit for each resource type in the web ACL AssociationConfig, for additional processing fees.

          • invalid_fallback_behavior
            Type: STRING
            Provider name: InvalidFallbackBehavior
            Description: What WAF should do if it fails to completely parse the JSON body. The options are the following:
            • EVALUATE_AS_STRING - Inspect the body as plain text. WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
            • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
            • NO_MATCH - Treat the web request as not matching the rule statement.
            If you don’t provide this setting, WAF parses and evaluates the content only up to the first parsing failure that it encounters. WAF parsing doesn’t fully validate the input JSON string, so parsing can succeed even for invalid JSON. When parsing succeeds, WAF doesn’t apply the fallback behavior. For more information, see JSON body in the WAF Developer Guide.
            
          • match_pattern
            Type: STRUCT

          • match_scope
            Type: STRING
            Provider name: MatchScope
            Description: The parts of the JSON to match against using the MatchPattern. If you specify ALL, WAF matches against keys and values. All does not require a match to be found in the keys and a match to be found in the values. It requires a match to be found in the keys or the values or both. To require a match in the keys and in the values, use a logical AND statement to combine two match rules, one that inspects the keys and another that inspects the values.

      • text_transformations
        Type: UNORDERED_LIST_STRUCT
        Provider name: TextTransformations
        Description: Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. Text transformations are used in rule match statements, to transform the FieldToMatch request component before inspecting it, and they’re used in rate-based rule statements, to transform request components before using them as custom aggregation keys. If you specify one or more transformations to apply, WAF performs all transformations on the specified content, starting from the lowest priority setting, and then uses the transformed component contents.
        
        • priority
          Type: INT32
          Provider name: Priority
          Description: Sets the relative processing order for multiple transformations. WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don’t need to be consecutive, but they must all be different.
          
        • type
          Type: STRING
          Provider name: Type
          Description: For detailed descriptions of each of the transformation types, see Text transformations in the WAF Developer Guide.
          
    • geo_match_statement
      Type: STRUCT
      Provider name: GeoMatchStatement
      Description: A rule statement that labels web requests by country and region and that matches against web requests based on country code. A geo match rule labels every request that it inspects regardless of whether it finds a match.
      • To manage requests only by country, you can use this statement by itself and specify the countries that you want to match against in the CountryCodes array.
      • Otherwise, configure your geo match rule with Count action so that it only labels requests. Then, add one or more label match rules to run after the geo match rule and configure them to match against the geographic labels and handle the requests as needed.
      WAF labels requests using the alpha-2 country and region codes from the International Organization for Standardization (ISO) 3166 standard. WAF determines the codes using either the IP address in the web request origin or, if you specify it, the address in the geo match ForwardedIPConfig. If you use the web request origin, the label formats are awswaf:clientip:geo:region:<ISO country code>-<ISO region code> and awswaf:clientip:geo:country:<ISO country code>. If you use a forwarded IP address, the label formats are awswaf:forwardedip:geo:region:<ISO country code>-<ISO region code> and awswaf:forwardedip:geo:country:<ISO country code>. For additional details, see Geographic match rule statement in the WAF Developer Guide.
      
      • country_codes
        Type: UNORDERED_LIST_STRING
        Provider name: CountryCodes
        Description: An array of two-character country codes that you want to match against, for example, [ “US”, “CN” ], from the alpha-2 country ISO codes of the ISO 3166 international standard. When you use a geo match statement just for the region and country labels that it adds to requests, you still have to supply a country code for the rule to evaluate. In this case, you configure the rule to only count matching requests, but it will still generate logging and count metrics for any matches. You can reduce the logging and metrics that the rule produces by specifying a country that’s unlikely to be a source of traffic to your site.
        
      • forwarded_ip_config
        Type: STRUCT
        Provider name: ForwardedIPConfig
        Description: The configuration for inspecting IP addresses in an HTTP header that you specify, instead of using the IP address that’s reported by the web request origin. Commonly, this is the X-Forwarded-For (XFF) header, but you can specify any header name. If the specified header isn’t present in the request, WAF doesn’t apply the rule to the web request at all.
        
        • fallback_behavior
          Type: STRING
          Provider name: FallbackBehavior
          Description: The match status to assign to the web request if the request doesn’t have a valid IP address in the specified position. If the specified header isn’t present in the request, WAF doesn’t apply the rule to the web request at all. You can specify the following fallback behaviors:
          • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
          • NO_MATCH - Treat the web request as not matching the rule statement.
        • header_name
          Type: STRING
          Provider name: HeaderName
          Description: The name of the HTTP header to use for the IP address. For example, to use the X-Forwarded-For (XFF) header, set this to X-Forwarded-For. If the specified header isn’t present in the request, WAF doesn’t apply the rule to the web request at all.
          
    • ip_set_reference_statement
      Type: STRUCT
      Provider name: IPSetReferenceStatement
      Description: A rule statement used to detect web requests coming from particular IP addresses or address ranges. To use this, create an IPSet that specifies the addresses you want to detect, then use the ARN of that set in this statement. To create an IP set, see CreateIPSet. Each IP set rule statement references an IP set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, WAF automatically updates all rules that reference it.
      
      • arn
        Type: STRING
        Provider name: ARN
        Description: The Amazon Resource Name (ARN) of the IPSet that this statement references.

          Provider name: FallbackBehavior
          Description: The match status to assign to the web request if the request doesn’t have a valid IP address in the specified position. If the specified header isn’t present in the request, WAF doesn’t apply the rule to the web request at all. You can specify the following fallback behaviors:
          • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
          • NO_MATCH - Treat the web request as not matching the rule statement.
        • header_name
          Type: STRING
          Provider name: HeaderName
          Description: The name of the HTTP header to use for the IP address. For example, to use the X-Forwarded-For (XFF) header, set this to X-Forwarded-For. If the specified header isn’t present in the request, WAF doesn’t apply the rule to the web request at all.
          
        • position
          Type: STRING
          Provider name: Position
          Description: The position in the header to search for the IP address. The header can contain IP addresses of the original client and also of proxies. For example, the header value could be 10.1.1.1, 127.0.0.0, 10.10.10.10 where the first IP address identifies the original client and the rest identify proxies that the request went through. The options for this setting are the following:
          • FIRST - Inspect the first IP address in the list of IP addresses in the header. This is usually the client’s original IP.
          • LAST - Inspect the last IP address in the list of IP addresses in the header.
          • ANY - Inspect all IP addresses in the header for a match. If the header contains more than 10 IP addresses, WAF inspects the last 10.
    • label_match_statement
      Type: STRUCT
      Provider name: LabelMatchStatement
      Description: A rule statement to match against labels that have been added to the web request by rules that have already run in the web ACL. The label match statement provides the label or namespace string to search for. The label string can represent a part or all of the fully qualified label name that had been added to the web request. Fully qualified labels have a prefix, optional namespaces, and label name. The prefix identifies the rule group or web ACL context of the rule that added the label. If you do not provide the fully qualified name in your label match string, WAF performs the search for labels that were added in the same context as the label match statement.
      
      • key
        Type: STRING
        Provider name: Key
        Description: The string to match against. The setting you provide for this depends on the match statement’s Scope setting:
        • If the Scope indicates LABEL, then this specification must include the name and can include any number of preceding namespace specifications and prefix up to providing the fully qualified label name.
        • If the Scope indicates NAMESPACE, then this specification can include any number of contiguous namespace strings, and can include the entire label namespace prefix from the rule group or web ACL where the label originates.
        Labels are case sensitive and components of a label must be separated by colon, for example NS1:NS2:name.
        
      • scope
        Type: STRING
        Provider name: Scope
        Description: Specify whether you want to match using the label name or just the namespace.
        
    • managed_rule_group_statement
      Type: STRUCT
      Provider name: ManagedRuleGroupStatement
      Description: A rule statement used to run the rules that are defined in a managed rule group. To use this, provide the vendor name and the name of the rule group in this statement. You can retrieve the required names by calling ListAvailableManagedRuleGroups. You cannot nest a ManagedRuleGroupStatement, for example for use inside a NotStatement or OrStatement. You cannot use a managed rule group inside another rule group. You can only reference a managed rule group as a top-level statement within a rule that you define in a web ACL. You are charged additional fees when you use the WAF Bot Control managed rule group AWSManagedRulesBotControlRuleSet, the WAF Fraud Control account takeover prevention (ATP) managed rule group AWSManagedRulesATPRuleSet, or the WAF Fraud Control account creation fraud prevention (ACFP) managed rule group AWSManagedRulesACFPRuleSet.

        • body
          Type: STRUCT
          Provider name: Body
          Description: Inspect the request body as plain text. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. WAF does not support inspecting the entire contents of the web request body if the body exceeds the limit for the resource type. When a web request body is larger than the limit, the underlying host service only forwards the contents that are within the limit to WAF for inspection.

          • For Application Load Balancer and AppSync, the limit is fixed at 8 KB (8,192 bytes).
          • For CloudFront, API Gateway, Amazon Cognito, App Runner, and Verified Access, the default limit is 16 KB (16,384 bytes), and you can increase the limit for each resource type in the web ACL AssociationConfig, for additional processing fees.
          For information about how to handle oversized request bodies, see the Body object configuration.
          
          • oversize_handling
            Type: STRING
            Provider name: OversizeHandling
            Description: What WAF should do if the body is larger than WAF can inspect. WAF does not support inspecting the entire contents of the web request body if the body exceeds the limit for the resource type. When a web request body is larger than the limit, the underlying host service only forwards the contents that are within the limit to WAF for inspection.
            • For Application Load Balancer and AppSync, the limit is fixed at 8 KB (8,192 bytes).
            • For CloudFront, API Gateway, Amazon Cognito, App Runner, and Verified Access, the default limit is 16 KB (16,384 bytes), and you can increase the limit for each resource type in the web ACL AssociationConfig, for additional processing fees.
            The options for oversize handling are the following:
            • CONTINUE - Inspect the available body contents normally, according to the rule inspection criteria.
            • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
            • NO_MATCH - Treat the web request as not matching the rule statement.
            You can combine the MATCH or NO_MATCH settings for oversize handling with your rule and web ACL action settings, so that you block any request whose body is over the limit.
            Default: CONTINUE

        • ja3_fingerprint
          Type: STRUCT
          Provider name: JA3Fingerprint
          Description: Available for use with Amazon CloudFront distributions and Application Load Balancers. Match against the request’s JA3 fingerprint. The JA3 fingerprint is a 32-character hash derived from the TLS Client Hello of an incoming request. This fingerprint serves as a unique identifier for the client’s TLS configuration. WAF calculates and logs this fingerprint for each request that has enough TLS Client Hello information for the calculation. Almost all web requests include this information. You can use this choice only with a string match ByteMatchStatement with the PositionalConstraint set to EXACTLY. You can obtain the JA3 fingerprint for client requests from the web ACL logs. If WAF is able to calculate the fingerprint, it includes it in the logs. For information about the logging fields, see Log fields in the WAF Developer Guide. Provide the JA3 fingerprint string from the logs in your string match statement specification, to match with any future requests that have the same TLS configuration.

            • NO_MATCH - Treat the web request as not matching the rule statement.

        • json_body
          Type: STRUCT
          Provider name: JsonBody
          Description: Inspect the request body as JSON. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. WAF does not support inspecting the entire contents of the web request body if the body exceeds the limit for the resource type. When a web request body is larger than the limit, the underlying host service only forwards the contents that are within the limit to WAF for inspection.

          • For Application Load Balancer and AppSync, the limit is fixed at 8 KB (8,192 bytes).
          • For CloudFront, API Gateway, Amazon Cognito, App Runner, and Verified Access, the default limit is 16 KB (16,384 bytes), and you can increase the limit for each resource type in the web ACL AssociationConfig, for additional processing fees.

          • invalid_fallback_behavior
            Type: STRING
            Provider name: InvalidFallbackBehavior
            Description: What WAF should do if it fails to completely parse the JSON body. The options are the following:
            • EVALUATE_AS_STRING - Inspect the body as plain text. WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
            • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
            • NO_MATCH - Treat the web request as not matching the rule statement.
            If you don’t provide this setting, WAF parses and evaluates the content only up to the first parsing failure that it encounters. WAF parsing doesn’t fully validate the input JSON string, so parsing can succeed even for invalid JSON. When parsing succeeds, WAF doesn’t apply the fallback behavior. For more information, see JSON body in the WAF Developer Guide.

For example, “IncludedPaths”: ["/dogs/0/name", “/dogs/1/name”]. For information about this syntax, see the Internet Engineering Task Force (IETF) documentation JavaScript Object Notation (JSON) Pointer. You must specify either this setting or the All setting, but not both. Don’t use this option to include all paths. Instead, use the All setting.
              

          • match_scope
            Type: STRING
            Provider name: MatchScope
            Description: The parts of the JSON to match against using the MatchPattern. If you specify ALL, WAF matches against keys and values. All does not require a match to be found in the keys and a match to be found in the values. It requires a match to be found in the keys or the values or both. To require a match in the keys and in the values, use a logical AND statement to combine two match rules, one that inspects the keys and another that inspects the values.
            
          • oversize_handling
            Type: STRING
            Provider name: OversizeHandling
            Description: What WAF should do if the body is larger than WAF can inspect. WAF does not support inspecting the entire contents of the web request body if the body exceeds the limit for the resource type. When a web request body is larger than the limit, the underlying host service only forwards the contents that are within the limit to WAF for inspection.
            • For Application Load Balancer and AppSync, the limit is fixed at 8 KB (8,192 bytes).
            • For CloudFront, API Gateway, Amazon Cognito, App Runner, and Verified Access, the default limit is 16 KB (16,384 bytes), and you can increase the limit for each resource type in the web ACL AssociationConfig, for additional processing fees.
            The options for oversize handling are the following:
            • CONTINUE - Inspect the available body contents normally, according to the rule inspection criteria.
            • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
            • NO_MATCH - Treat the web request as not matching the rule statement.
            You can combine the MATCH or NO_MATCH settings for oversize handling with your rule and web ACL action settings, so that you block any request whose body is over the limit.
            Default: CONTINUE

        Type: UNORDERED_LIST_STRUCT
        Provider name: TextTransformations
        Description: Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. Text transformations are used in rule match statements, to transform the FieldToMatch request component before inspecting it, and they’re used in rate-based rule statements, to transform request components before using them as custom aggregation keys. If you specify one or more transformations to apply, WAF performs all transformations on the specified content, starting from the lowest priority setting, and then uses the transformed component contents.
        
        • priority
          Type: INT32
          Provider name: Priority
          Description: Sets the relative processing order for multiple transformations. WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don’t need to be consecutive, but they must all be different.

      Provider name: RegexPatternSetReferenceStatement
      Description: A rule statement used to search web request components for matches with regular expressions. To use this, create a RegexPatternSet that specifies the expressions that you want to detect, then use the ARN of that set in this statement. A web request matches the pattern set rule statement if the request component matches any of the patterns in the set. To create a regex pattern set, see CreateRegexPatternSet. Each regex pattern set rule statement references a regex pattern set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, WAF automatically updates all rules that reference it.
      
      • arn
        Type: STRING
        Provider name: ARN
        Description: The Amazon Resource Name (ARN) of the RegexPatternSet that this statement references.

          Description: Inspect the request body as plain text. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. WAF does not support inspecting the entire contents of the web request body if the body exceeds the limit for the resource type. When a web request body is larger than the limit, the underlying host service only forwards the contents that are within the limit to WAF for inspection.

          • For Application Load Balancer and AppSync, the limit is fixed at 8 KB (8,192 bytes).
          • For CloudFront, API Gateway, Amazon Cognito, App Runner, and Verified Access, the default limit is 16 KB (16,384 bytes), and you can increase the limit for each resource type in the web ACL AssociationConfig, for additional processing fees.
          For information about how to handle oversized request bodies, see the Body object configuration.

          Type: STRUCT
          Provider name: JA3Fingerprint
          Description: Available for use with Amazon CloudFront distributions and Application Load Balancers. Match against the request’s JA3 fingerprint. The JA3 fingerprint is a 32-character hash derived from the TLS Client Hello of an incoming request. This fingerprint serves as a unique identifier for the client’s TLS configuration. WAF calculates and logs this fingerprint for each request that has enough TLS Client Hello information for the calculation. Almost all web requests include this information. You can use this choice only with a string match ByteMatchStatement with the PositionalConstraint set to EXACTLY. You can obtain the JA3 fingerprint for client requests from the web ACL logs. If WAF is able to calculate the fingerprint, it includes it in the logs. For information about the logging fields, see Log fields in the WAF Developer Guide. Provide the JA3 fingerprint string from the logs in your string match statement specification, to match with any future requests that have the same TLS configuration.

            • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
            • NO_MATCH - Treat the web request as not matching the rule statement.

        • json_body
          Type: STRUCT
          Provider name: JsonBody
          Description: Inspect the request body as JSON. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. WAF does not support inspecting the entire contents of the web request body if the body exceeds the limit for the resource type. When a web request body is larger than the limit, the underlying host service only forwards the contents that are within the limit to WAF for inspection.

          • For Application Load Balancer and AppSync, the limit is fixed at 8 KB (8,192 bytes).
          • For CloudFront, API Gateway, Amazon Cognito, App Runner, and Verified Access, the default limit is 16 KB (16,384 bytes), and you can increase the limit for each resource type in the web ACL AssociationConfig, for additional processing fees.

          • invalid_fallback_behavior
            Type: STRING
            Provider name: InvalidFallbackBehavior
            Description: What WAF should do if it fails to completely parse the JSON body. The options are the following:
            • EVALUATE_AS_STRING - Inspect the body as plain text. WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
            • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
            • NO_MATCH - Treat the web request as not matching the rule statement.
            If you don’t provide this setting, WAF parses and evaluates the content only up to the first parsing failure that it encounters. WAF parsing doesn’t fully validate the input JSON string, so parsing can succeed even for invalid JSON. When parsing succeeds, WAF doesn’t apply the fallback behavior. For more information, see JSON body in the WAF Developer Guide.
            
          • match_pattern
            Type: STRUCT

For example, “IncludedPaths”: ["/dogs/0/name", “/dogs/1/name”]. For information about this syntax, see the Internet Engineering Task Force (IETF) documentation JavaScript Object Notation (JSON) Pointer. You must specify either this setting or the All setting, but not both. Don’t use this option to include all paths. Instead, use the All setting.
              

          • match_scope
            Type: STRING
            Provider name: MatchScope
            Description: The parts of the JSON to match against using the MatchPattern. If you specify ALL, WAF matches against keys and values. All does not require a match to be found in the keys and a match to be found in the values. It requires a match to be found in the keys or the values or both. To require a match in the keys and in the values, use a logical AND statement to combine two match rules, one that inspects the keys and another that inspects the values.

            • For Application Load Balancer and AppSync, the limit is fixed at 8 KB (8,192 bytes).
            • For CloudFront, API Gateway, Amazon Cognito, App Runner, and Verified Access, the default limit is 16 KB (16,384 bytes), and you can increase the limit for each resource type in the web ACL AssociationConfig, for additional processing fees.
            The options for oversize handling are the following:
            • CONTINUE - Inspect the available body contents normally, according to the rule inspection criteria.
            • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
            • NO_MATCH - Treat the web request as not matching the rule statement.
            You can combine the MATCH or NO_MATCH settings for oversize handling with your rule and web ACL action settings, so that you block any request whose body is over the limit.
            Default: CONTINUE

        Description: Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. Text transformations are used in rule match statements, to transform the FieldToMatch request component before inspecting it, and they’re used in rate-based rule statements, to transform request components before using them as custom aggregation keys. If you specify one or more transformations to apply, WAF performs all transformations on the specified content, starting from the lowest priority setting, and then uses the transformed component contents.

      Provider name: SizeConstraintStatement
      Description: A rule statement that compares a number of bytes against the size of a request component, using a comparison operator, such as greater than (>) or less than (<). For example, you can use a size constraint statement to look for query strings that are longer than 100 bytes. If you configure WAF to inspect the request body, WAF inspects only the number of bytes in the body up to the limit for the web ACL and protected resource type. If you know that the request body for your web requests should never exceed the inspection limit, you can use a size constraint statement to block requests that have a larger request body size. For more information about the inspection limits, see Body and JsonBody settings for the FieldToMatch data type. If you choose URI for the value of Part of the request to filter on, the slash (/) in the URI counts as one character. For example, the URI /logo.jpg is nine characters long.

        • body
          Type: STRUCT
          Provider name: Body
          Description: Inspect the request body as plain text. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. WAF does not support inspecting the entire contents of the web request body if the body exceeds the limit for the resource type. When a web request body is larger than the limit, the underlying host service only forwards the contents that are within the limit to WAF for inspection.

          • For Application Load Balancer and AppSync, the limit is fixed at 8 KB (8,192 bytes).
          • For CloudFront, API Gateway, Amazon Cognito, App Runner, and Verified Access, the default limit is 16 KB (16,384 bytes), and you can increase the limit for each resource type in the web ACL AssociationConfig, for additional processing fees.
          For information about how to handle oversized request bodies, see the Body object configuration.
          
          • oversize_handling
            Type: STRING

            Description: What WAF should do if the body is larger than WAF can inspect. WAF does not support inspecting the entire contents of the web request body if the body exceeds the limit for the resource type. When a web request body is larger than the limit, the underlying host service only forwards the contents that are within the limit to WAF for inspection.
            • For Application Load Balancer and AppSync, the limit is fixed at 8 KB (8,192 bytes).
            • For CloudFront, API Gateway, Amazon Cognito, App Runner, and Verified Access, the default limit is 16 KB (16,384 bytes), and you can increase the limit for each resource type in the web ACL AssociationConfig, for additional processing fees.
            The options for oversize handling are the following:
            • CONTINUE - Inspect the available body contents normally, according to the rule inspection criteria.
            • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
            • NO_MATCH - Treat the web request as not matching the rule statement.
            You can combine the MATCH or NO_MATCH settings for oversize handling with your rule and web ACL action settings, so that you block any request whose body is over the limit.
            Default: CONTINUE

All does not require a match to be found in the keys and a match to be found in the values. It requires a match to be found in the keys or the values or both. To require a match in the keys and in the values, use a logical AND statement to combine two match rules, one that inspects the keys and another that inspects the values.
            
          • oversize_handling
            Type: STRING
            Provider name: OversizeHandling
            Description: What WAF should do if the headers of the request are more numerous or larger than WAF can inspect. WAF does not support inspecting the entire contents of request headers when they exceed 8 KB (8192 bytes) or 200 total headers. The underlying host service forwards a maximum of 200 headers and at most 8 KB of header contents to WAF. The options for oversize handling are the following:
            • CONTINUE - Inspect the available headers normally, according to the rule inspection criteria.
            • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
            • NO_MATCH - Treat the web request as not matching the rule statement.

        • ja3_fingerprint
          Type: STRUCT
          Provider name: JA3Fingerprint
          Description: Available for use with Amazon CloudFront distributions and Application Load Balancers. Match against the request’s JA3 fingerprint. The JA3 fingerprint is a 32-character hash derived from the TLS Client Hello of an incoming request. This fingerprint serves as a unique identifier for the client’s TLS configuration. WAF calculates and logs this fingerprint for each request that has enough TLS Client Hello information for the calculation. Almost all web requests include this information. You can use this choice only with a string match ByteMatchStatement with the PositionalConstraint set to EXACTLY. You can obtain the JA3 fingerprint for client requests from the web ACL logs. If WAF is able to calculate the fingerprint, it includes it in the logs. For information about the logging fields, see Log fields in the WAF Developer Guide. Provide the JA3 fingerprint string from the logs in your string match statement specification, to match with any future requests that have the same TLS configuration.
          

          • fallback_behavior
            Type: STRING
            Provider name: FallbackBehavior
            Description: The match status to assign to the web request if the request doesn’t have a JA3 fingerprint. You can specify the following fallback behaviors:
            • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
            • NO_MATCH - Treat the web request as not matching the rule statement.

        • json_body
          Type: STRUCT
          Provider name: JsonBody
          Description: Inspect the request body as JSON. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. WAF does not support inspecting the entire contents of the web request body if the body exceeds the limit for the resource type. When a web request body is larger than the limit, the underlying host service only forwards the contents that are within the limit to WAF for inspection.

          • For Application Load Balancer and AppSync, the limit is fixed at 8 KB (8,192 bytes).
          • For CloudFront, API Gateway, Amazon Cognito, App Runner, and Verified Access, the default limit is 16 KB (16,384 bytes), and you can increase the limit for each resource type in the web ACL AssociationConfig, for additional processing fees.
          For information about how to handle oversized request bodies, see the JsonBody object configuration.
          
          • invalid_fallback_behavior
            Type: STRING
            Provider name: InvalidFallbackBehavior
            Description: What WAF should do if it fails to completely parse the JSON body. The options are the following:
            • EVALUATE_AS_STRING - Inspect the body as plain text. WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
            • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
            • NO_MATCH - Treat the web request as not matching the rule statement.
            If you don’t provide this setting, WAF parses and evaluates the content only up to the first parsing failure that it encounters. WAF parsing doesn’t fully validate the input JSON string, so parsing can succeed even for invalid JSON. When parsing succeeds, WAF doesn’t apply the fallback behavior. For more information, see JSON body in the WAF Developer Guide.
            
          • match_pattern
            Type: STRUCT

For example, “IncludedPaths”: ["/dogs/0/name", “/dogs/1/name”]. For information about this syntax, see the Internet Engineering Task Force (IETF) documentation JavaScript Object Notation (JSON) Pointer. You must specify either this setting or the All setting, but not both. Don’t use this option to include all paths. Instead, use the All setting.
              

          • match_scope
            Type: STRING
            Provider name: MatchScope
            Description: The parts of the JSON to match against using the MatchPattern. If you specify ALL, WAF matches against keys and values. All does not require a match to be found in the keys and a match to be found in the values. It requires a match to be found in the keys or the values or both. To require a match in the keys and in the values, use a logical AND statement to combine two match rules, one that inspects the keys and another that inspects the values.

        Type: UNORDERED_LIST_STRUCT
        Provider name: TextTransformations
        Description: Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. Text transformations are used in rule match statements, to transform the FieldToMatch request component before inspecting it, and they’re used in rate-based rule statements, to transform request components before using them as custom aggregation keys. If you specify one or more transformations to apply, WAF performs all transformations on the specified content, starting from the lowest priority setting, and then uses the transformed component contents.

            If you don’t provide this setting, WAF parses and evaluates the content only up to the first parsing failure that it encounters. WAF parsing doesn’t fully validate the input JSON string, so parsing can succeed even for invalid JSON. When parsing succeeds, WAF doesn’t apply the fallback behavior. For more information, see JSON body in the WAF Developer Guide.
            
          • match_pattern
            Type: STRUCT
            Provider name: MatchPattern
            Description: The patterns to look for in the JSON body. WAF inspects the results of these pattern matches against the rule inspection criteria.
            

            • all
              Type: STRUCT
              Provider name: All
              Description: Match all of the elements. See also MatchScope in JsonBody. You must specify either this setting or the IncludedPaths setting, but not both.

              Provider name: IncludedPaths
              Description: Match only the specified include paths. See also MatchScope in JsonBody. Provide the include paths using JSON Pointer syntax. For example, “IncludedPaths”: ["/dogs/0/name", “/dogs/1/name”]. For information about this syntax, see the Internet Engineering Task Force (IETF) documentation JavaScript Object Notation (JSON) Pointer. You must specify either this setting or the All setting, but not both. Don’t use this option to include all paths. Instead, use the All setting.
              

          • match_scope
            Type: STRING
            Provider name: MatchScope
            Description: The parts of the JSON to match against using the MatchPattern. If you specify ALL, WAF matches against keys and values. All does not require a match to be found in the keys and a match to be found in the values. It requires a match to be found in the keys or the values or both. To require a match in the keys and in the values, use a logical AND statement to combine two match rules, one that inspects the keys and another that inspects the values.
            
          • oversize_handling
            Type: STRING
            Provider name: OversizeHandling
            Description: What WAF should do if the body is larger than WAF can inspect. WAF does not support inspecting the entire contents of the web request body if the body exceeds the limit for the resource type. When a web request body is larger than the limit, the underlying host service only forwards the contents that are within the limit to WAF for inspection.
            • For Application Load Balancer and AppSync, the limit is fixed at 8 KB (8,192 bytes).
            • For CloudFront, API Gateway, Amazon Cognito, App Runner, and Verified Access, the default limit is 16 KB (16,384 bytes), and you can increase the limit for each resource type in the web ACL AssociationConfig, for additional processing fees.
            The options for oversize handling are the following:
            • CONTINUE - Inspect the available body contents normally, according to the rule inspection criteria.
            • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
            • NO_MATCH - Treat the web request as not matching the rule statement.
            You can combine the MATCH or NO_MATCH settings for oversize handling with your rule and web ACL action settings, so that you block any request whose body is over the limit.
            Default: CONTINUE

        Type: STRING
        Provider name: SensitivityLevel
        Description: The sensitivity that you want WAF to use to inspect for SQL injection attacks. HIGH detects more attacks, but might generate more false positives, especially if your web requests frequently contain unusual strings. For information about identifying and mitigating false positives, see Testing and tuning in the WAF Developer Guide. LOW is generally a better choice for resources that already have other protections against SQL injection attacks or that have a low tolerance for false positives.
        Default: LOW
      • text_transformations
        Type: UNORDERED_LIST_STRUCT
        Provider name: TextTransformations
        Description: Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. Text transformations are used in rule match statements, to transform the FieldToMatch request component before inspecting it, and they’re used in rate-based rule statements, to transform request components before using them as custom aggregation keys. If you specify one or more transformations to apply, WAF performs all transformations on the specified content, starting from the lowest priority setting, and then uses the transformed component contents.
        
        • priority
          Type: INT32
          Provider name: Priority
          Description: Sets the relative processing order for multiple transformations. WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don’t need to be consecutive, but they must all be different.
          
        • type
          Type: STRING
          Provider name: Type
          Description: For detailed descriptions of each of the transformation types, see Text transformations in the WAF Developer Guide.

        • body
          Type: STRUCT
          Provider name: Body
          Description: Inspect the request body as plain text. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. WAF does not support inspecting the entire contents of the web request body if the body exceeds the limit for the resource type. When a web request body is larger than the limit, the underlying host service only forwards the contents that are within the limit to WAF for inspection.

          • For Application Load Balancer and AppSync, the limit is fixed at 8 KB (8,192 bytes).
          • For CloudFront, API Gateway, Amazon Cognito, App Runner, and Verified Access, the default limit is 16 KB (16,384 bytes), and you can increase the limit for each resource type in the web ACL AssociationConfig, for additional processing fees.
          For information about how to handle oversized request bodies, see the Body object configuration.

          • match_scope
            Type: STRING
            Provider name: MatchScope
            Description: The parts of the cookies to inspect with the rule inspection criteria. If you specify ALL, WAF inspects both keys and values. All does not require a match to be found in the keys and a match to be found in the values. It requires a match to be found in the keys or the values or both. To require a match in the keys and in the values, use a logical AND statement to combine two match rules, one that inspects the keys and another that inspects the values.
            
          • oversize_handling
            Type: STRING
            Provider name: OversizeHandling

          Type: STRUCT
          Provider name: JA3Fingerprint
          Description: Available for use with Amazon CloudFront distributions and Application Load Balancers. Match against the request’s JA3 fingerprint. The JA3 fingerprint is a 32-character hash derived from the TLS Client Hello of an incoming request. This fingerprint serves as a unique identifier for the client’s TLS configuration. WAF calculates and logs this fingerprint for each request that has enough TLS Client Hello information for the calculation. Almost all web requests include this information. You can use this choice only with a string match ByteMatchStatement with the PositionalConstraint set to EXACTLY. You can obtain the JA3 fingerprint for client requests from the web ACL logs. If WAF is able to calculate the fingerprint, it includes it in the logs. For information about the logging fields, see Log fields in the WAF Developer Guide. Provide the JA3 fingerprint string from the logs in your string match statement specification, to match with any future requests that have the same TLS configuration.

            • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
            • NO_MATCH - Treat the web request as not matching the rule statement.

        • json_body
          Type: STRUCT
          Provider name: JsonBody
          Description: Inspect the request body as JSON. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. WAF does not support inspecting the entire contents of the web request body if the body exceeds the limit for the resource type. When a web request body is larger than the limit, the underlying host service only forwards the contents that are within the limit to WAF for inspection.

          • For Application Load Balancer and AppSync, the limit is fixed at 8 KB (8,192 bytes).
          • For CloudFront, API Gateway, Amazon Cognito, App Runner, and Verified Access, the default limit is 16 KB (16,384 bytes), and you can increase the limit for each resource type in the web ACL AssociationConfig, for additional processing fees.

            Type: STRING
            Provider name: InvalidFallbackBehavior
            Description: What WAF should do if it fails to completely parse the JSON body. The options are the following:
            • EVALUATE_AS_STRING - Inspect the body as plain text. WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
            • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
            • NO_MATCH - Treat the web request as not matching the rule statement.
            If you don’t provide this setting, WAF parses and evaluates the content only up to the first parsing failure that it encounters. WAF parsing doesn’t fully validate the input JSON string, so parsing can succeed even for invalid JSON. When parsing succeeds, WAF doesn’t apply the fallback behavior. For more information, see JSON body in the WAF Developer Guide.

For example, “IncludedPaths”: ["/dogs/0/name", “/dogs/1/name”]. For information about this syntax, see the Internet Engineering Task Force (IETF) documentation JavaScript Object Notation (JSON) Pointer. You must specify either this setting or the All setting, but not both. Don’t use this option to include all paths. Instead, use the All setting.
              

          • match_scope
            Type: STRING
            Provider name: MatchScope
            Description: The parts of the JSON to match against using the MatchPattern. If you specify ALL, WAF matches against keys and values. All does not require a match to be found in the keys and a match to be found in the values. It requires a match to be found in the keys or the values or both. To require a match in the keys and in the values, use a logical AND statement to combine two match rules, one that inspects the keys and another that inspects the values.

          Description: Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer. This setting isn’t case sensitive. Example JSON: “SingleHeader”: { “Name”: “haystack” } Alternately, you can filter and inspect all headers with the Headers FieldToMatch setting.
          

          • name
            Type: STRING
            Provider name: Name
            Description: The name of the query header to inspect.
            

        • single_query_argument
          Type: STRUCT
          Provider name: SingleQueryArgument
          Description: Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion. The name can be up to 30 characters long and isn’t case sensitive. Example JSON: “SingleQueryArgument”: { “Name”: “myArgument” }
          

          • name
            Type: STRING
            Provider name: Name
            Description: The name of the query argument to inspect.
            

        • uri_path
          Type: STRUCT
          Provider name: UriPath
          Description: Inspect the request URI path. This is the part of the web request that identifies a resource, for example, /images/daily-ad.jpg.
          

      • text_transformations
        Type: UNORDERED_LIST_STRUCT
        Provider name: TextTransformations
        Description: Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. Text transformations are used in rule match statements, to transform the FieldToMatch request component before inspecting it, and they’re used in rate-based rule statements, to transform request components before using them as custom aggregation keys. If you specify one or more transformations to apply, WAF performs all transformations on the specified content, starting from the lowest priority setting, and then uses the transformed component contents.
        
        • priority
          Type: INT32
          Provider name: Priority
          Description: Sets the relative processing order for multiple transformations. WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don’t need to be consecutive, but they must all be different.
          
        • type
          Type: STRING
          Provider name: Type
          Description: For detailed descriptions of each of the transformation types, see Text transformations in the WAF Developer Guide.
          
  • visibility_config
    Type: STRUCT
    Provider name: VisibilityConfig
    Description: Defines and enables Amazon CloudWatch metrics and web request sample collection. If you change the name of a Rule after you create it and you want the rule’s metric name to reflect the change, update the metric name as well. WAF doesn’t automatically update the metric name.
    
    • cloud_watch_metrics_enabled
      Type: BOOLEAN
      Provider name: CloudWatchMetricsEnabled
      Description: Indicates whether the associated resource sends metrics to Amazon CloudWatch. For the list of available metrics, see WAF Metrics in the WAF Developer Guide. For web ACLs, the metrics are for web requests that have the web ACL default action applied. WAF applies the default action to web requests that pass the inspection of all rules in the web ACL without being either allowed or blocked. For more information, see The web ACL default action in the WAF Developer Guide.
      
    • metric_name
      Type: STRING
      Provider name: MetricName
      Description: A name of the Amazon CloudWatch metric dimension. The name can contain only the characters: A-Z, a-z, 0-9, - (hyphen), and _ (underscore). The name can be from one to 128 characters long. It can’t contain whitespace or metric names that are reserved for WAF, for example All and Default_Action.
      
    • sampled_requests_enabled
      Type: BOOLEAN
      Provider name: SampledRequestsEnabled
      Description: Indicates whether WAF should store a sampling of the web requests that match the rules. You can view the sampled requests through the WAF console. Request sampling doesn’t provide a field redaction option, and any field redaction that you specify in your logging configuration doesn’t affect sampling. The only way to exclude fields from request sampling is by disabling sampling in the web ACL visibility configuration.
      
• token_domains
  Type: UNORDERED_LIST_STRING
  Provider name: TokenDomains
  Description: Specifies the domains that WAF should accept in a web request token. This enables the use of tokens across multiple protected websites. When WAF provides a token, it uses the domain of the Amazon Web Services resource that the web ACL is protecting. If you don’t specify a list of token domains, WAF accepts tokens only for the domain of the protected resource. With a token domain list, WAF accepts the resource’s host domain plus all domains in the token domain list, including their prefixed subdomains.
