you could have the page that you don't want the user to go back from be a browser window without a toolbar, but they could still right-click and choose back if they are usin ie on windows. or you could experiment with using javascript to manipulate the history property of the window object.

Sorry Yaar I was a bit busy .
To implement what I was mentioning --
In the page which you don't want the user to come back and view
you can write javascript on to the page like -
<script>
window.forward(1);
</script>
you may use print writer or anything you want but put it in Head tag of the page you are building .
If you have any difficulty or need another approach kindly mail be back .

Let me give the exact code :
window.history.forward(1);

HI,
I hope you're not doing that to the general public without a good reason - some type of 2step form process that MUST be completed or similar.
Most visitors dislike it when the site takes control. Forcing them to close the browser etc.
If you disable the back button your telling them "there's only one way outta this page....MY WAY".
But perhaps this is for an intranet app so it's not so drastic.
Bye,

I am developing an application, where user logs in and can log out from any page. How can I make sure once the user logs out he is not able to go back to the page from where he logged out.

window.history.forward(1);
This code works when I dont want the user to visit the page where this code is included.
Could anyone help me in that reagrd..
thanks

slight addition to the above description:
suppose user browses in following manner

L O G O U T
^ ^ ^ ^
| | | |
1 - > 2 - > 3 - > 4 - > 5
from page 1 to 2 to 3 and so on... user could log out from any of the page 1, 2, 3,4 or 5. I want user to go back and forth between pages using back button. But dont want him to go back once user logs out.

please help...
thanks

Hi Arpit,
If u r using session in u'r pages it easy to block user once he logged out.Use session.invalidate(JSP) method in u'r logout page.
If its a servlet use instanceName of the session(for Eg:currSess)
currSess.invalidate().
And its always better to post u'r messages in a seperate thread if its different from current thread.
Regards...Syam.
