Logout question

[Chandrakanta]

After logout, how to prevent back button. I am using Mozilla Firefiox. Please help me.

why? if the user is logged out (s)he can’t access protected content without logging in again.

If you hit the back button in a browser, a cached version of the page is displayed to the user. You need to prevent the browser from caching the page so that when someone hits the back button (after logging out) the sensitive content is not displayed.
