Re: session expires

A tricky way to achive this is: 1. Start the session when the user request the login page 2. Send a hidden field with the PHPSESSID 3. When receiving the post compare the current session id with the submitted by the form, if they match it's likely the session has not expired. Other solution: If you can do it, to put an IFRAME with a page which autorefresh itself by less than the time the session expires. Manu.
