// 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 RegexMatchSet. You then use UpdateRegexMatchSet to
// identify the part of a web request that you want AWS WAF to inspect, such as the
// values of the User-Agent header or the query string. For example, you can create
// a RegexMatchSet that contains a RegexMatchTuple that looks for any requests with
// User-Agent headers that match a RegexPatternSet with pattern B[a@]dB[o0]t. You
// can then configure AWS WAF to reject those requests. To create and configure a
// RegexMatchSet, perform the following steps:
//
// * Use GetChangeToken to get the
// change token that you provide in the ChangeToken parameter of a
// CreateRegexMatchSet request.
//
// * Submit a CreateRegexMatchSet request.
//
// * Use
// GetChangeToken to get the change token that you provide in the ChangeToken
// parameter of an UpdateRegexMatchSet request.
//
// * Submit an UpdateRegexMatchSet
// request to specify the part of the request that you want AWS WAF to inspect (for
// example, the header or the URI) and the value, using a RegexPatternSet, 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/).
