For all on the mailing list, Travis and I spoke on IRC; The solution here is to have a single handler that talks to both servers.
Also, to clarify the architecture, the front-end does regular HTTP requests and the backend server listens on a websocket for request from their data service. -Jason On 22:29 Thu 04 Oct , Dalton Barreto wrote: > 2012/10/4 Travis Spencer <[email protected]>: > > Hi All, > > > > I'm wondering if it is possible to tie two Mongrel2 servers together > > and pass data between their handlers using 0MQ.
