Thanks very much for your reply.
Yes, I am using form authentication to verify user info in
a database. Here is the scenario:
1) User login using the account ABC and successfully login.
2) Another user got the login ID and password from his
friend and login from another machine with the login ID
ABC.

How can I allow just one session to login with the same
login ID? One solution is to kick out the first guy who
login when the second guy try to login. But how? That was
my question. I don't really understand how to solve this
problem by "store them in a temporary
table and then check the user against the table when they
log in?"

Thanks!
Kelvin
