sirs,

its really normal for a website to cater to multiple logins of users, say, employees in an intranet and they need to access to a website.

a user logs in a main portal then clicks my portal. it then passes parameters from a main portal to my portal. I am now able to automatically log in a user thanks to fooberichu who guided me in creating the module. 

the problem is, if a user madz does not log out, another user joe who would log in, would be logging in as madz. but I did not use sessions and someone told me that I should use sessions. but another told me that dotnetnuke can handle this problem on multiple logins, and handle variables like how session variables. Is this correct? please enlighten me. or should I really use session? thanks so much.
