How to get the HTTP response code of the page:
If you mainly used curl for troubleshooting, you actually will be surprised that HTTP response code is not readily available on PJS … although its not that hard to get either

console.log('---- Loading a web page -----');
var page = require('webpage').create(), 
    url = 'http://mandog-test.ml/';

page.open(url, function (status) {
  console.log("Status: " + status); // This is not the status we are looking for
  console.log('---- Exiting ... ----');

page.onResourceReceived = function(response) {
  console.log(response.status); // This is the status we need

$ ./phantomjs ../phantom_test.js 
---- Loading a web page -----
---- Exiting ... ----

– What is that null – lets use --debug flag to inspect more closely — any other flags?
– Why is the response code returned multiple times and how to display it once accurately?
