Connection Limits

I have done some more research, and it doesn't look like connection limits on the pool members will meet my requirements. I believe that once a member falls below the limit, it will start taking connections again, which I do not want to happen. I started working on an iRule....

when RULE_INIT {     
   array set ::active_connections { }   
   }   
      
   when HTTP_REQUEST {     
   if LB::status pool pool1 member 10.10.10.1 up   
           set servername server1   
   if active_connections($servername) <= 1000   
   use pool pool1 member 10.10.10.1 80   
   incr ::active_connections($servername)   
   else LB::status pool pool1 member 10.10.10.1 80 down   
   use pool pool1 member 10.10.10.2 80   
                   set servername server2   
                   incr ::active_connections($servername)   
                      
   if LB::status pool pool1 member 10.10.10.2 80 up   
           set servername server2   
   if active_connections($servername) <= 1000   
   use pool pool1 member 10.10.10.2 80   
   incr ::active_connections($servername)   
   else LB::status pool pool1 member 10.10.10.2 80 down   
   use pool pool1 member 10.10.10.3 80   
                   set servername server3   
                   incr ::active_connections($servername)   
      
   else use 10.10.10.3   
           set servername server3   
   use pool pool1 member 10.10.10.3 80   
   incr ::active_connections($servername)   
      
   }   
      
   when CLIENT_CLOSED {     
          incr ::active_connections($servername) -1       
   }     
  

I know I need more brackets, but other than that, will this work?
