A function I made that wraps the node http.request function to make it a little more friendly. In my case I am using it for API route testing.
// module dependencies
var http = require('http'),
url = require('url');
/**
* UrlReq - Wraps the http.request function making it nice for unit testing APIs.
*
* @param {string} reqUrl The required url in any form
* @param {object} options An options object (this is optional)
