session login

[eluser]r0mel[/eluser]
@cronix: Sir, just want to ask about the problem of my code, i knew it was a bit buggy. I used a session but i have a problem with that. In pure php, i can handle the session as what i had expected, it couldn't return/access to the home after i logout, though i press the back button in th browser still it was in the login form which is correct. With the session in codeigniter, i have a problem with that because the back button in the browser still can go through the home page though i checked if has a session login or not.
please guide me sir. thank you sir
