Would a method clone work in this case?
===

I'm trying to build a debug proxy so I can see requests and responses when calling various API's, but I'm stuck where I'm trying to send data to the [original method][1].

How can I also send the chunk to the original method?


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

	var write2;

	function write (chunk, encoding) {

		/*  
			error: Object #<Object> has no method '_implicitHeader'
			because write2 is not a clone.
		*/
		//write2(chunk, encoding);

		if (Buffer.isBuffer(chunk)) {
			console.log(chunk.toString(encoding));
		}
	}


	var server = httpProxy.createServer(function (req, res, proxy) {
	
		// copy .write
		write2 = res.write;
		// monkey-patch .write
		res.write = write;
	
		proxy.proxyRequest(req, res, {
			host: req.headers.host,
			port: 80
		});

	});

	server.listen(8000);
