--
-- 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 <http://docs.aws.amazon.com/waf/latest/developerguide/ AWS WAF Developer Guide> .
