working with casperjs and http status codes

gistfile1.js

var casper = require('casper').create({
  httpStatusHandlers: {
    404: function(self, resource) {
      self.echo(resource.url + ' not found (404)');
    },
    500: function(self, resource) {
      self.echo(resource.url + ' gave an error (500)');
    }
  },
  verbose: true
});

casper.start('http://mywebsite/404', function() {
  this.echo(this.result.status);
  this.echo(this.currentHTTPStatus);
  this.echo('We suppose this url return an HTTP 404');
});

casper.run(function() {
  this.echo('Done.').exit();
});

I know you made this 5 years ago, but I am currently using this for a project I am working on and this example was key in helping me understand how to use it. So with that being said, I can't stress a big enough THANK YOU!!!!!! Greatly appreciated 5 years down the road by at least one person
