Hello Travis, I'm afraid this is not possible to be done the way you are trying to do. The handler specs are specifically for the communication between m2 and backend handlers. > 2.

Just add a route that is a proxy and ensure that it points to the IP:Port of the second m2 server. Hope it helps. -- Dalton Barreto http://daltonmatos.com
