The UrlMembershipCondition class uses Url evidence to determine if an assembly or application domain qualifies for membership of a CodeGroup. The Url property contains the URL required to qualify for membership and can include a wildcard as the final element for example, http://www.oreilly.com/apps/*. The value of the Url property is initially set in the UrlMembershipCondition constructor.

During policy resolution, the Check( ) method enumerates the provided Evidence collection and determines if it contains a Url evidence object. If so, UrlMembershipCondition tests for CodeGroup membership by comparing the string contained in its Url property with the URL contained in the Url.Value property.
