It's a caching issue. Search the archives, it's been discussed before.

Dear Servlet-Interest users,

I have an online ordering application and I am having problems logging
out. Once a user has placed an order and he clicks on the Logoff
button, I call a servlet where I destroy the session and redirect the
user to a new page with the message that he has logged out
successfully. But, when I hit the back button on the browser, it again
takes me to the previous page. I want the user to go to the login page
when he hits the back button on the browser and force him to login
again to access any of the pages, instead of the previous page in his
session.


How can I achieve this functionality? Thanks for any help in advance!

Sincerely,

--Andy.
