Prevent duplicate users from logging in?

[dragonturtle]

Is it possible to use regular ASP to prevent duplicate users from logging into a site? E.g. If Johnny is logged in, another user can't use Johnny's user/pass to log in simultaneously.

I thought about using a database column called [logged] which is set to 1 when a user is logged in, and set to 0 when logged out. Problem is I don't know how to reset it to 0 if the user doesn't hit the logout button (session timeout or browser closes).

try session.end in a global.asa file. You can find tons of info on global.asa.

Hope this help.

Or you could add a field on the database that marks when Johnny logs in and clears it when Johnny logs out if that field is populated already quick them out

use a session.end script to manage this with a log out button...if he doesn't press the log out button then he'll have to wait for the session timeout script to clear the entry...
