Irule help 302 + maintain URI

It sounds like you want to load balance the requests but not have it handle the outgoing traffic. There is a technique called npath routing which sounds like it's what you need w/o putting in an iRule.

The nPath method of traffic management increases outbound throughput because packets do not need to be transmitted to the BIG-IP system for translation and forwarding to the next hop.

Check it out.
