Multiple Application Session collision

[eluser]stalebrew[/eluser]
I am new to CodeIgniter and everything has been great thus far.

I have one small problem with session collisions. I have 2 applications; one for the front end and one for the admin. If I am logged into the admin, and then I login to the front-end with a user account, the admin application will now read the user account session data(and vice versa). I have tried changing the session cookie prefix and cookie name but nothing has worked.

This scenario will most likely not happen in the real world with this particular application but for some applications it might be a problem.

Am I just missing something?

*ADDED: By the way, I'm using Native Sessions.
