TCP/HTTP proxy in node.js

Question

I'd like to create a simple TCP and HTTP proxy in node.js - For example, the proxy listens on port 8080 and redirects all TCP requests to 127.0.0.1:8181 and all HTTP requests to 127.0.0.0.1:8282

I found this snippet on Google for a simple HTTP proxy in 20 lines of code:

var http = require('http');

http.createServer(function(request, response) {
  var proxy = http.createClient(80, request.headers['host'])
  var proxy_request = proxy.request(request.method, request.url, request.headers);
  proxy_request.addListener('response', function (proxy_response) {
    proxy_response.addListener('data', function(chunk) {
      response.write(chunk, 'binary');
    });
    proxy_response.addListener('end', function() {
      response.end();
    });
    response.writeHead(proxy_response.statusCode, proxy_response.headers);
  });
  request.addListener('data', function(chunk) {
    proxy_request.write(chunk, 'binary');
  });
  request.addListener('end', function() {
    proxy_request.end();
  });
}).listen(8080);

So basically I need to listen for any sort of request on 8080, guess if it's TCP or HTTP, and then proxy the request to the right path. Any tips using the snippet above?

Thanks

nodejitsu has open-sourced a node-http-proxy which I think you try instead. It is documented, actively developed.
