Hi Girish, 1. You cannot modify the browser Back button (any thing on the client's computer for that matter). 2. I strongly oppose the use of Cookies for tracking the user login, due to security reasons. Cookies are saved on the client's computer and he/she can easily modify the information present. But that is impossible with sessions. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
