Parallel service request

example.js

function(req, res) {

  var response = {};
  var urls = ["http://test.com", "http://other.test.com"];

  // Iterate the urls
  services.forEach(function(service){
    get(service, function(err, data){
      // Handle error
      if(err) res.render('error', err);

      // merge data w/ response here
      urls.pop(service);

      // This means we have all of the data
      if(!urls.length) {
        res.render('template', data);
      }
    });
  });

}
