hi hardik, thanks for ur reply, if you don't mine, can u give me a sample on that

Yes,
you may use a table for keeping track of all the details of active sessions when one user successfully login. I think it will be also a good idea to record the login time and use a timeout.
As a session variable is not valid when user change the browser it will not be really handy to use simple session variables for your purpose.

And take care you does not LOCK OUT a user who accedentally forget to logout.
