--
-- __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 @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:
--
-- 1.  Use GetChangeToken to get the change token that you provide in the
--     @ChangeToken@ parameter of a @CreateRegexPatternSet@ request.
--
-- 2.  Submit a @CreateRegexPatternSet@ request.
--
-- 3.  Use @GetChangeToken@ to get the change token that you provide in the
--     @ChangeToken@ parameter of an @UpdateRegexPatternSet@ request.
--
-- 4.  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
-- <https://docs.aws.amazon.com/waf/latest/developerguide/ AWS WAF Developer Guide>.
