Best way to block multiple logins/same user ?
843841Dec 5 2003 — edited Dec 6 2003What is the best way to block/prevent someone from logging in more than once at the same time with the same userID?
I was thinking to post to a database whenever a user logs in/out but then every time a user does this there has to be a database call to see if that user is already logged in. This solution doesn't seem to efficient or maybe it is.?? Anyone with a better solution?
