The session timeout demo simply shows a way to configure the RadNotification to show at a certain time and how its callback can renew the session. Where you obtain the length for the ShowInterval depends on your scenario, yet the session timeout is likely to work in all major cases. The control itself does not monitor the session and is not related to the authentication on the site. You can, for example, check if the user is authenticated and if not - simply remove the notification if this is what you want to do (Visible=false). The formt authentication ticket itself is just the way the session / user id is passed between the server and the client.
