IP Check Instead of Name Check?

In the activeUsers function in functions_common.asp, when a user is to be added to the array, the IP address is checked to see if the user is already in the array.

This is causing problems on my forum, because some of my users are behind a firewall, so the first one to login, is the only one shown in the active users list.

Is there any reason, that anyone can see that making this change would be bad?

Use: If saryActiveUsers(2, intArrayPass) = strLoggedInUsername Then
Instead Of: If saryActiveUsers(0, intArrayPass) = strIPAddress Then

       

Then how about a "compound key"? User name + IP?
