Global connection count variable

I suppose in an irule you can create ::CNT

Here is somewhat an example

 
 when RULE_INIT { 
    set ::CNT 0 
   } 
   when HTTP_REQUEST { 
    incr ::CNT 
   } 
    
 when CLIENT_CLOSED { 
    ; decrement current connection counter 
    if {$::CNT > 0} { 
      incr ::cnt -1 
    } 
   } 
 

However, I am a bit puzzled as to why you would want to Round Robin a connection to multiple pools. This would indicate the nodes in the multiple pools are the same, therefore you wouldn't need to separate them in multiple pools but in one pool.
