Irule Help persistence

Thank you for your help. I have cookie persistence enabled with override connection limit enabled in the profile, however when I tested I would receive the web page content and then my next click on the site I would receive "sorry page". Again thank you for your help.

 if { [class match [IP::client_addr] equals private_net] } {

Ok. So I kinda stepped back and re thought how to approach this and this is what I have came up with. Instead of usinig connection limits, I'm using session limits. Please take a look at this Irule and tell me if you see any issues or ways to optimize this. Also I don't believe it's possible, but is there anyway to do this with a session based cookie intead of using a timout value?

   set static::sorrypage {
        
            
        We're Sorry
            
        
            We're Sorry.  Our servers are currently over capacity and certain areas of our site may be temporarily unavailable.  We're working to resolve the issue as quickly as possible.
