Irule Help persistence

Also to note I was able to get the persistence to work. However what I run into is, let's say that I have a limit restriction of 100 on each one of my members in the perspective pool. When a user comes in and he is subject to the restriction until he gets a persistence record. Upon being persistent, he then can bypass the connection limit. What the problem is if this happens then your connection limit really isn't doing any good because the persistent records continue to grow, which makes the connections grow on the backend servers. What I really need is a way to control the amount of persistent records that can be issued out at once. That way I can truly control how many users can access the system at a given point.
