How to create multiple sessions in cakephp

I have cakephp application which has two separate logins one for admin and one for employee. I am using session to store login details.but when i logged out from admin it automatically logouts from employee and vice versa. can i use two different sessions for that?

Why would you do that? Is it a user personalization method?

Sry now it is solved. I have used session key at admin side to store details.
