// 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. Inserts or deletes Predicate objects in a Rule . Each Predicate
// object identifies a predicate, such as a ByteMatchSet or an IPSet , that
// specifies the web requests that you want to allow, block, or count. If you add
// more than one predicate to a Rule , a request must match all of the
// specifications to be allowed, blocked, or counted. For example, suppose that you
// add the following to a Rule :
//   - A ByteMatchSet that matches the value BadBot in the User-Agent header
//   - An IPSet that matches the IP address 192.0.2.44
//
// You then add the Rule to a WebACL and specify that you want to block requests
// that satisfy the Rule . For a request to be blocked, the User-Agent header in
// the request must contain the value BadBot and the request must originate from
// the IP address 192.0.2.44. To create and configure a Rule , perform the
// following steps:
//   - Create and update the predicates that you want to include in the Rule .
//   - Create the Rule . See CreateRule .
//   - Use GetChangeToken to get the change token that you provide in the
//     ChangeToken parameter of an UpdateRule request.
//   - Submit an UpdateRule request to add predicates to the Rule .
//   - Create and update a WebACL that contains the Rule . See CreateWebACL .
//
// If you want to replace one ByteMatchSet or IPSet with another, you delete the
// existing one and add the new one. For more information about how to use the AWS
// WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide (https://docs.aws.amazon.com/waf/latest/developerguide/)
// .
