Socket.io and non-domain-level Proxies

[toji]

I have a socket.io server that I am trying to integrate with a larger content server. Since this is one of several services that may be running on this particular server, IT would like to proxy to my service from a sub-directory of the TLD. (ie: http://domain.com/my-service/) Everything else about this setup seems to be working fine (I even got it serving the socket client script properly) except that socket.io refuses to attempt it's connection to anything but http://domain.com, choosing to treat "my-service" as a namespace instead of part of the actual path.

Since there may eventually be other services at this site that require websocket connections, it is not feasible to reroute all domain level socket traffic to my service's proxy. Is there a way that I can force socket.io to attempt it's connection to an exact URL?
