I'm trying to stop/disable the back button functionality of the browser when a user logs out of my CodeIgniter (PHP) app. But, I think the browser is caching the page so it becomes visible despite the session being destroyed from logout.
I know the session is dead because when the user tries to do anything (click any link etc) they are kicked out through the methods in my controller.
It's not ideal to have the back button working in this manner since the previous page contains confidential information.
Not a clue how to tackle this one, maybe a redirect page in between (but then the user could slam the back button really quick right?), help!
Thanks.
