switching session settings in different controllers (same app)

I presume there is some kind of login process for the admin to access the back-end, so you could simply set a session variable so you know this has happened.

Code:

$this->session->set_userdata('admin', 1);

Then, condition your front-end so it only ends the session when the admin session variable is not set.

Code:

if (($this->session->userdata('admin') != 1):
    // End front end session stuff...
endif;
