foo.js

// inspiration: https://github.com/damienklinnert/appdotnet
var request = require('request');

foo = function(cb) {
  var opts = { uri: 'http://appd01:8111' };
  
	request.get(opts, function(err ,resp, body) {
		if (err) { return cb(err); }
		
		return cb(null, resp, body);
	});
};

foo(function(err, response, body) {
	if (err) {
		console.log("error: %s", err);
	} else {
		console.log("status code: %s", response.statusCode);	
		console.log("body:\n %s", body);
