public class UserTag
extends SecureTag

JSP tag that renders the tag body if the current user known to the system, either from a successful login attempt (not necessarily during the current session) or from 'RememberMe' services.

Note: This is less restrictive than the AuthenticatedTag since it only assumes the user is who they say they are, either via a current session login or via Remember Me services, which makes no guarantee the user is who they say they are. The AuthenticatedTag however guarantees that the current user has logged in during their current session, proving they really are who they say they are.

The logically opposite tag of this one is the GuestTag.
