title: No response using express proxy route
body: <p>I've written a small proxy with nodejs, express and htt-proxy. It works well for serving local files but fails when it comes to proxy to external api:</p>
  
  <pre><code>var express = require('express'),
      app = express.createServer(),
      httpProxy = require('http-proxy');
  
  
  app.use(express.bodyParser());
  app.listen(process.env.PORT || 1235);
  
  var proxy = new httpProxy.RoutingProxy();
  
  app.get('/', function(req, res) {
      res.sendfile(__dirname + '/index.html');
  });
  app.get('/js/*', function(req, res) {
      res.sendfile(__dirname + req.url);
  });
  app.get('/css/*', function(req, res) {
      res.sendfile(__dirname + req.url);
  });
  
  app.all('/*', function(req, res) {
      req.url = 'v1/public/yql?q=show%20tables&amp;format=json&amp;callback=';
      proxy.proxyRequest(req, res, {
          host: 'query.yahooapis.com', //yahoo is just an example to verify its not the apis fault
          port: 8080
      });
  
  });
  </code></pre>
  
  <p>The problem is that there is no response from the yahoo api, maybe there is an response but i dont came up in the browser.</p>
