I am using session.invalidate() on the logout of my application.
1. click the logout button . It redirects to the login page.
2. click the browser back button directs to the login page again.

But when i run my application on a different machine
1. click the logout button . it redirects to login page.
2. click the browser back button .It popsup with the error message.
3. i click on the browser refresh button . it redirects to the application instead of logon page.

Why is application behaving differently on diffent machines???
