HTTP Session Limit

If the intention is to keep the connections to the pool of servers below a certain threshold, this would work. But I don't see how this would not end up interfering with an active application session if that user happens to return a transaction at a time that it was over the connection limit-- they may get a 'sorry' redirect in mid-session. For most web-based application sessions, it is a series of transactions where each transaction may be in a separate connection.
