This ruleset controls which HTTP response header fields the XTM device allows. You can add, delete, or modify rules. Many of the HTTP response headers that are allowed in the default configuration are described in RFC 2616. For more information, see http://www.ietf.org/rfc/rfc2616.txt.
If you modified a predefined proxy action, when you save the changes you are prompted to clone (copy) your settings to a new action.
For more information on predefined proxy actions, see About Proxy Actions.
