Use Database Online table for user sessions.

2009/8/27 Balasubramanyam A <knowledge.wea...@gmail.com>:
Hello,

I've written a simple application, where users need to login to access the features of the application. I want to develop login system such that, if user is already logged in, the application should not allow the users to
login with the same login credentials. How do I accomplish this?

Regards,
Balu

Set a flag in the login table when the user logs in. You will need a process to unset this when a user logs out or if the session times out or the user will not be able to log in again.
