This is AWS WAF Classic documentation.

For more information, see AWS WAF Classic in the developer guide.

For the latest version of AWS WAF , use the AWS WAF V2 API and see the AWS WAF Developer Guide . With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Contains the Rules that identify the requests that you want to allow, block, or count. In a WebACL , you also specify a default action ( ALLOW or BLOCK ), and the action for each Rule that you add to a WebACL , for example, block requests from specified IP addresses or block requests from specified referrers. You also associate the WebACL with a Amazon CloudFront distribution to identify the requests that you want AWS WAF to filter. If you add more than one Rule to a WebACL , a request needs to match only one of the specifications to be allowed, blocked, or counted.

Example: 

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.waf.*;
 CfnWebACL cfnWebACL = CfnWebACL.Builder.create(this, "MyCfnWebACL")
         .defaultAction(WafActionProperty.builder()
                 .type("type")
                 .build())
         .metricName("metricName")
         .name("name")
         // the properties below are optional
         .rules(List.of(ActivatedRuleProperty.builder()
                 .priority(123)
                 .ruleId("ruleId")
                 // the properties below are optional
                 .action(WafActionProperty.builder()
                         .type("type")
                         .build())
                 .build()))
         .build();
