-- This is __AWS WAF Classic__ documentation. For more information, see
-- <https://docs.aws.amazon.com/waf/latest/developerguide/classic-waf-chapter.html AWS WAF Classic>
-- in the developer guide.
--
-- __For the latest version of AWS WAF__, use the AWS WAFV2 API and see the
-- <https://docs.aws.amazon.com/waf/latest/developerguide/waf-chapter.html AWS WAF Developer Guide>.
-- 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:
--
-- 1.  Use GetChangeToken to get the change token that you provide in the
--     @ChangeToken@ parameter of a @CreateRegexMatchSet@ request.
--
-- 2.  Submit a @CreateRegexMatchSet@ request.
--
-- 3.  Use @GetChangeToken@ to get the change token that you provide in the
--     @ChangeToken@ parameter of an @UpdateRegexMatchSet@ request.
--
-- 4.  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
-- <https://docs.aws.amazon.com/waf/latest/developerguide/ AWS WAF Developer Guide>.
