		#### Setup a stand-alone proxy server with proxy request header re-writing
		This example shows how you can proxy a request using your own HTTP server that
		modifies the outgoing proxy request by adding a special header.

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

		//
		// Create a proxy server with custom application logic
		//
		var proxy = httpProxy.createProxyServer({});

		// To modify the proxy connection before data is sent, you can listen
		// for the 'proxyReq' event. When the event is fired, you will receive
		// the following arguments:
		// (http.ClientRequest proxyReq, http.IncomingMessage req,
		// http.ServerResponse res, Object options). This mechanism is useful when
		// you need to modify the proxy request before the proxy connection
		// is made to the target.
		//
		proxy.on('proxyReq', function(proxyReq, req, res, options) {
		proxyReq.setHeader('X-Special-Proxy-Header', 'foobar');
		});

		var server = require('http').createServer(function(req, res) {
		// You can define here your custom logic to handle the request
		// and then proxy the request.
		proxy.web(req, res, {
		target: 'http://127.0.0.1:5060'
		});
		});

		console.log("listening on port 5050")
		server.listen(5050);
		```
