API Reference

AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

Container for the parameters to the UpdateXssMatchSet operation. Inserts or deletes XssMatchTuple objects (filters) in an XssMatchSet. For each XssMatchTuple object, you specify the following values:

You use XssMatchSet objects to specify which CloudFront requests you want to allow, block, or count. For example, if you're receiving requests that contain cross-site scripting attacks in the request body and you want to block the requests, you can create an XssMatchSet with the applicable settings, and then configure AWS WAF to block the requests.

To create and configure an XssMatchSet, perform the following steps:

  1. Submit a CreateXssMatchSet request.

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

  3. Submit an UpdateXssMatchSet request to specify the parts of web requests that you want AWS WAF to inspect for cross-site scripting attacks.

For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.
