// 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 Rule , which contains the IPSet objects, ByteMatchSet
// objects, and other predicates that identify the requests that you want to block.
// If you add more than one predicate to a Rule , a request must match all of the
// specifications to be allowed or blocked. For example, suppose that you add the
// following to a Rule :
//   - An IPSet that matches the IP address 192.0.2.44/32
//   - A ByteMatchSet that matches BadBot in the User-Agent header
//
// You then add the Rule to a WebACL and specify that you want to blocks requests
// that satisfy the Rule . For a request to be blocked, it must come from the IP
// address 192.0.2.44 and the User-Agent header in the request must contain the
// value BadBot . To create and configure a Rule , perform the following steps:
//   - Create and update the predicates that you want to include in the Rule . For
//     more information, see CreateByteMatchSet , CreateIPSet , and
//     CreateSqlInjectionMatchSet .
//   - Use GetChangeToken to get the change token that you provide in the
//     ChangeToken parameter of a CreateRule request.
//   - Submit a CreateRule request.
//   - Use GetChangeToken to get the change token that you provide in the
//     ChangeToken parameter of an UpdateRule request.
//   - Submit an UpdateRule request to specify the predicates that you want to
//     include in the Rule .
//   - Create and update a WebACL that contains the Rule . For more information,
//     see CreateWebACL .
//
// 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/)
