// 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 RegexPatternSet. You then use UpdateRegexPatternSet to
// specify the regular expression (regex) pattern that you want AWS WAF to search
// for, such as B[a@]dB[o0]t. You can then configure AWS WAF to reject those
// requests. To create and configure a RegexPatternSet, perform the following
// steps:
//
// * Use GetChangeToken to get the change token that you provide in the
// ChangeToken parameter of a CreateRegexPatternSet request.
//
// * Submit a
// CreateRegexPatternSet request.
//
// * Use GetChangeToken to get the change token
// that you provide in the ChangeToken parameter of an UpdateRegexPatternSet
// request.
//
// * Submit an UpdateRegexPatternSet request to specify the string that
// you want AWS WAF to watch for.
//
// 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/).
