back button- Confirm form resubmission using jsp, servlet and filter

Question

I followed some examples I saw here to write my code but I get a confirm form resubmission when I press the browser back button after logout. I am using two jsp pages, the index page which contains the login form and the welcome page which displays after suuccessful login. A login servlet which processes the login data and sets the session atribute and a logout servlet which removes session atribute and invalidate the session.

A filter which checks for session attribute and sets the no-cache...on the browser. all the other aspect works fine but when I press the back button after logout,it displays "confirm form resubmission". please I think am not getting something right. I need help. Thank you.

You can't alter the back button behavior. – Roman C Apr 25 '15 at 17:59 — Roman C, Apr 25 '15 at 17:59

Are you doing logout with post method? If yes, For logout browser sending some data to server, when you press back button brower assumes your trying to reload, and ask you to confirm form submit. It wont be a problem until unless, user logout properly other wise you have to check your filters.
