I have a HTTP web server and I'm trying to set it up behind a HTTPS proxy server. I've tried the example that's in the repository: https://github.com/http-party/node-http-proxy/blob/master/examples/http/proxy-https-to-http.js but I'm always getting ERR_EMPTY_RESPONSE in browser.

Example code

var https = require('https'),
    http  = require('http'),
    util  = require('util'),
    path  = require('path'),
    fs    = require('fs'),
    colors = require('colors'),
    httpProxy = require('../../lib/http-proxy'),
    fixturesDir = path.join(__dirname, '..', '..', 'test', 'fixtures');

//
// Create the target HTTP server
//
http.createServer(function (req, res) {
  res.writeHead(200, { 'Content-Type': 'text/plain' });
  res.write('hello http over https\n');
  res.end();
}).listen(9009);

//
// Create the HTTPS proxy server listening on port 8000
//
httpProxy.createServer({
  target: {
    host: 'localhost',
    port: 9009
  },
  ssl: {
    key: fs.readFileSync(path.join(fixturesDir, 'agent2-key.pem'), 'utf8'),
    cert: fs.readFileSync(path.join(fixturesDir, 'agent2-cert.pem'), 'utf8')
  }
}).listen(8009);

console.log('https proxy server'.blue + ' started '.green.bold + 'on port '.blue + '8009'.yellow);
console.log('http server '.blue + 'started '.green.bold + 'on port '.blue + '9009 '.yellow);

Error

Browser is pointed to use 127.0.0.1:8009 proxy.

Does anybody know what's wrong ? Any suggestion is appreciated.
