Note

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.

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 AWS WAF Developer Guide.
