Note

AWS WAF Classic support will end on September 30, 2025.

This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide.

For the latest version of AWS WAF , use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.

The RegexPatternSet specifies 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.
