How do I use node.js http-proxy for logging HTTP traffic in a computer?

I am trying to implement the simplest example:

var http = require('http'),

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



httpProxy.createServer(function (req, res, proxy) {

    //

    // I would add logging here

    //

    proxy.proxyRequest(req, res, { host: 'www.google.com', port: 80 });

}).listen(18000);

When I configure my browser to use this proxy and I navigate to www.google.com I receive no response. What is that I am doing wrong?

I'm using Windows 7 Chrome

Here is an simple example how to log requests.
I use a similar to log all my domains to one database.

I copied much from http://blog.nodejitsu.com/http-proxy-middlewares (archived)

var fs = require('fs'),

    http = require('http'),

    httpProxy = require('http-proxy'),

        

logger = function() {    

  // This will only run once

  var logFile = fs.createWriteStream('./requests.log');



  return function (request, response, next) { 

    // This will run on each request.

    logFile.write(JSON.stringify(request.headers, true, 2));

    next();

  }

}



httpProxy.createServer(

  logger(), // <-- Here is all the magic

  {

    hostnameOnly: true,

    router: {

      'example1.com': '127.0.0.1:8001', // server on localhost:8001

      'example2.com': '127.0.0.1:8002'  // server 2 on localhost:8002

  }

}).listen(8000);
