well, what exactly was the problem. did you change 'username' and 'password' to your session name for those. also i didn't think about this before but when the session is destroyed the page has to be refreshed before the logout will be successful. maybe after the session is destroyed, have the page refresh
this should work. it did for me

First, do not disable my back button. It's 2nd on my list of most hated website activities. (1st is opening new browser windows.)
Ok, now to try to understand what you're trying to do: If you want to prevent a user who logged out from seeing the information on a previous user's welcome.php page, your best bet is to tell the browser the page is out of date and needs refreshed. That way, the browser won't load the page from cache and instead load the page from the server.
I think using a "META" tag with the option "expires" (Search for "META expires" and see what comes up) is the way to go here.

i was just thinking about it and i thought you might be able to use page views as an option.
use a session variable to hold the number and when someone visits a page the count increases. if the count goes above 2 then logout will happen. i have never tested this so i have no idea if it works, but i think it might.
