What would be the best approach to limit the # of sessions
that can be active at one time. Page access is restricted by
session variables. In an extreme example, someone could give out
their username and password to 100 people, and they would all be
able to login at the same time. I want to limit to one person at a
time. Any advice?
Obviously the login script will need to add timestamp or
trigger something in a tracking database table... however, without
the users logging off, how would I allow a new login once that
browser is closed or that session is timed out.
