Random port appended in OmniAuth callback?

[ghost]

I am using node-http-proxy with the following code:

var railsProxy = new httpProxy.HttpProxy({ 
  target: { 
    host: 'localhost', 
    port: CONFIG.RAILS_PORT,
  }
});

var socketProxy = new httpProxy.HttpProxy({ 
  target: {
    host: 'localhost', 
    port: CONFIG.SOCKET_PORT,
  }
});

var reverseProxy = http.createServer(function(req, res) { 
  switch(req.headers.host) { 
    case "socket.mysite.com":
      socketProxy.proxyRequest(req, res);
      break;
    default: 
      railsProxy.proxyRequest(req, res);
      break;
  }
});

Currently, this is breaking my omniauth for facebook. When I click "login with facebook" on my site,

I am 404'ed with the following url in my url bar:

http://mysite.com:49592/users/auth/facebook/callback?code=AQBab4LR3HFBEs9Oo0yGqR-RbZHDTymeUJwmyl9Fg1MW9DBvwBIbH_vsECR5jcq_excWaCZGU-WiEUv8hPfZ_C9FT0xHZ28CMueDWAtb3_aZWduRjGMvuSDey_DPNi03O7K62S2mthQ6_qWP5GCGU-jZCaYg1Hrn1RXZxowuhCxz-yrlSxP27upshnsWwZWFY9I#_=_

Another attempt at this will produce port 49602. Which is extremely weird as I was testing my site on http://mysite.com. Where does the random port come from?

I have decided to test what is causing this, so I wget to see the url redirection:

If I remove the port from the url, I am actually able to login. Anyone know why I am seeing this random port being inserted into my url?

Not sure. Could be a Facebook issue behind proxies.

This looks related to #341 and you're getting the ephemeral port.

No longer an issue.
