Question

I have a node.js app that serve static files (html, js, css). Among the static files, some ajax request are done (with /TEST in the request). I need those request to be proxied to another server running on localhost:213445. The static pages are correctly displayed but when it comes to proxied request it hangs forever…

My code is:

var express = require("express");
var httpProxy = require('http-proxy');
var fs = require('fs');

// Create https server
var app = express.createServer({
    key: fs.readFileSync('privatekey.pem'),
    cert: fs.readFileSync('certificate.pem')
});

// Handle static files
app.use(express.static(__dirname + '/public'));

// Proxy request
app.all('/TEST/*',function(req, res){
  // Remove '/TEST' part from query string
  req.url = '/' + req.url.split('/').slice(2).join('/');

  // Create proxy
  var proxy = new httpProxy.HttpProxy();
  proxy.proxyRequest(req, res, {
     host: 'localhost',
     port: 21345,
     enableXForwarded: false,
     buffer: proxy.buffer(req)
  });
});

// Run application
app.listen(10443);

I have the same issue. If you comment out the

// Handle static files
app.use(express.static(__dirname + '/public'));

you will see that the the proxy works.

Not sure how to fix it if express.static is used

This is an express problem.
The Connect / Express middlewares are doing non-standard things to your response object,
breaks streaming. Try using the raw request module instead of http-proxy.
