BIG-IP : iRule to route uri-forms for all hosts

Thanks again Michael. In my case, the goal is for certain uri-forms to be routed to an entirely separate traffic-manager ( custom code built around HAProxy ) which performs all further handling of the request. I'm not at all sure about this, but I believe the other traffic-manager sends its responses directly to the client -- I don't believe responses flow back through BIG-IP ( is this even possible ? I need to research and find out for sure ). If so, BIG-IP will never have opportunity to execute HTTP_RESPONSE event. Subsequent requests on the same keep-alive connection should be processed anew -- because might be a request for a different uri that may or may not be contained in the set of uri-forms routed to the other traffic-manager.
