P.S. The previous description mostly applies to native session management.
 For those using servlet-container based sessions (Shiro's default
configuration), the same concepts apply down to the SessionManager.  From
that point on, the ServletContainerSessionManager implementation differs
greatly from the native SessionManagers since it will delegate everything
to the Servlet Container for session management.
