// This is AWS WAF Classic documentation. For more information, see AWS WAF Classic (https://docs.aws.amazon.com/waf/latest/developerguide/classic-waf-chapter.html)
// in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API
// and see the AWS WAF Developer Guide (https://docs.aws.amazon.com/waf/latest/developerguide/waf-chapter.html)
// . With the latest version, AWS WAF has a single set of endpoints for regional
// and global use. Creates a WebACL , which contains the Rules that identify the
// CloudFront web requests that you want to allow, block, or count. AWS WAF
// evaluates Rules in order based on the value of Priority for each Rule . You also
// specify a default action, either ALLOW or BLOCK . If a web request doesn't match
// any of the Rules in a WebACL , AWS WAF responds to the request with the default
// action. To create and configure a WebACL , perform the following steps:
//   - Create and update the ByteMatchSet objects and other predicates that you
//     want to include in Rules . For more information, see CreateByteMatchSet ,
//     UpdateByteMatchSet , CreateIPSet , UpdateIPSet , CreateSqlInjectionMatchSet ,
//     and UpdateSqlInjectionMatchSet .
//   - Create and update the Rules that you want to include in the WebACL . For
//     more information, see CreateRule and UpdateRule .
//   - Use GetChangeToken to get the change token that you provide in the
//     ChangeToken parameter of a CreateWebACL request.
//   - Submit a CreateWebACL request.
//   - Use GetChangeToken to get the change token that you provide in the
//     ChangeToken parameter of an UpdateWebACL request.
//   - Submit an UpdateWebACL request to specify the Rules that you want to include
//     in the WebACL , to specify the default action, and to associate the WebACL
//     with a CloudFront distribution.
//
// For more information about how to use the AWS WAF API, see the AWS WAF
// Developer Guide (https://docs.aws.amazon.com/waf/latest/developerguide/) .
