What if the user want to stay online more time ? That's why you have the page that must remain open and is requesting a page on the server every 30 seconds - that's what's keeping the session alive. This should be implemented at the network level so I encourage you to investigate what's possible there. -Stuart -- Stuart Dallas 3ft9 Ltd http://3ft9.com/
