The Site evidence class specifies the fully qualified host name from where an assembly was loaded—for example, www.oreilly.com. The site name is passed as a System.String to the Site constructor, and is accessible through the Name property. The static CreateFromUrl( ) method enables easy creation of Site objects from URL strings.

During policy resolution, the SiteMembershipCondition class uses Site evidence to test whether an assembly or application domain qualifies for membership of a CodeGroup.

Because the Site class implements the IIdentityPermissionFactory interface, an assembly or application domain with Site evidence will contain an appropriately configured System.Security.Permissions.SiteIdentityPermission object in its grant set.
