I’m using forms authentication to log users onto my website.
But what happens if someone is trying to login with the same details from different machines at the same time? Is there a way to check this?
Ideally, I’d like to display a message to the second attempt saying that that user account is already logged in..
Thanks
Hold that information server-side (the list of users that are already logged in). Then, on each login, check if not already in that list.
