Hi Christopher,
That iRule does a hash on the cleint IP to select a pool member. You could do that. Another option would be to let LTM make the load balancing decision using the algorithm specified on the pool and then use persist uie to ensure clients get back to the same pool member. You'd basically replace the scan and pool command with persist uie $tcip_header 3600:

Either method should work, but I'd guess the default load balancing method and UIE persistence will be a bit more efficient in terms of CPU utilization.
