after logout jsp retain values

hi,

I am developing simple three page application. first one login page second confirmation page that displays the name of user who logged in and it has also link for logout, which is logout.jsp page.

I wirtten session.invalidate() in logout.jsp, but when i press window's back button it again shows the confirmation page as well as the username that was stored in session variable.

I want to know if it is distroying all seesion , how i can see it again, rather i should see "the page has been expired' kind of messag.
