Hi Deon,

It's more exact and faster to perform an IP address comparison versus a string comparison on the client IP address. It's actually the third example on the IP::addr wiki page which I was referring to: 

 
 when CLIENT_ACCEPTED { 
    if { [IP::addr [IP::client_addr]/24 equals 172.22.166.0] } { 
       pool CSS_2 
    } 
 }

On a standard TCP VIP, CLIENT_ACCEPTED is triggered when the client establishes a TCP connection with the VIP. CLIENT_DATA is only triggered if you collect the TCP payload with TCP::collect. There is more detail on events on the events wiki page (Click here).
