Hi guys,
How would you allow only one user at a time? I mean one user of the account,
so for example say john888 logged in, and another user of the same name,
john888, trys to log in and I want to block that user with a message saying
the user is already logged in. I thought about writing to the DB everytime a
user logs in, but it might be a bit too expensive. Any ideas? Using session
beans? Thank you very much guys.
