node-http-proxy websocket超时与Socket.io

Question

For some reason http-proxy causes socket.io based websocket connection reconnect after every 2 minutes. Before reconnection messages are working just fine between client and server. If I bypass proxy, the websocket connection works without reconnections. Proxy configuration is very basic and follows an example from nodejitsu.

var http = require('http'),
  httpProxy = require('http-proxy');

var options = {
  hostNameOnly: true,
  router: {
    'example.com/sockets/': '127.0.0.1:9001'
  }
};

var proxyServer = httpProxy.createServer(options);
proxyServer.listen(80);

I have also tried to change the timeout option in configuration but this does not have an affect to the reconnection problem.

timeout: 120000 // override the default 2 minute http socket timeout value in milliseconds

Software versions: Ubuntu 12.04 server, node.js 0.8.16, http-proxy 0.8.7, socket.io 0.8.7.

This works perfectly on dev Mac (10.8.3) and on Ubuntu desktop 12.04 (virtualbox) but not on server.

Set the timeout in options which you are passing to createServer. options.timeout for socket timeout and options.proxyTimeout to allow outgoing socket to timeout so that we could show an error page at the initial request.
