Hi, I am using a session variable to create an area where customers can access certain pages via login/password. If they successfully login, I create a session variable and initialize it with their logon username.
I also have a logout button which unregisters the session variables and issues a session_unset() and session_destroy(). Then is takes them back to the login page. Now all my pages in this area first check if the session variable is set and if not, displays a message that the user must first login. I noticed that after logging out and clicking click on the "Back" button in my browser, it takes me back to the previous page which is does NOT display the warning that the user must login. However, when I click on the Refresh, it does. Is this some sort of caching problem? I note that other sites with similar setups do not have this problem. When I click on the "Back" button, I saw an expiry message. How can I emulate this please?
