A P3P policy can be applied to a set of URLs on a Web site. This is done by listing the URLs or URL patterns to which the policy applies, and then listing and URLs or URL patterns to exclude from that list. For more information on this process, see the policy reference file overview.
For example, to indicate that a policy covers all of the URLs in the /servlet subtree except for /servlet/exception, enter /servlet* in the "URLs covered" list, and /servlet/exception in the "URLs to exclude" list.
