Hi Shanaj,
Thanx fr replyin, but actually i'd already used these headers in my page, still not working. I have designed my page using Front-page so I hd jst set these headers as Meta tags with the 'HTTP-EQUIV' attribute..and in my Jsp I'm just checking the session obj , as far the processing is concerned , all that is done in a Servlet,
The thing is that I've a webappln in wich a user after logging in fills up certain subscriptions and there is a 'logout' link on every page,on clicking it the user's session is invalidated saying session.invalid ate() . Then on all the pages I just check if the session = null , if yes then the user should be redirected back to the home-page..but the thing is that on saying back the control doesn't even go into the scriptlet in order to chek this..it just directly displays the previous page ...and thus u cn see all the previous pages just by saying 'previous' and 'forward'. I' m still working on it and as a temp solution I've disabled the ''back' button thru JavaScript.
