Inserts or deletes RegexPatternString objects in a RegexPatternSet. For each RegexPatternString object, you specify the following values:

For example, you can create a RegexPatternString such as B[a@]dB[o0]t. AWS WAF will match this RegexPatternString to:

To create and configure a RegexPatternSet, perform the following steps:

  1. Create a RegexPatternSet. For more information, see CreateRegexPatternSet.

  2. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateRegexPatternSet request.

  3. Submit an UpdateRegexPatternSet request to specify the regular expression pattern 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.

Note:

For .NET Core and PCL this operation is only available in asynchronous form. Please refer to UpdateRegexPatternSetAsync.
