Fake Referrer with Phantomjs

fake-referrer.phantom.js

var system = require('system');

// Exit in case of wrong parameter count.
if (system.args.length !== 3) {
    console.log('Usage: scriptname targetUrl referrer');
    console.log('example: $> phantomjs fake-referrer.phantom.js http://example.com http://referrer.example.com');
	phantom.exit();
}

// Set the important pieces
var targetUrl = system.args[1];
var referrer = system.args[2];

console.log('Going to open '+targetUrl+' with the referrer '+referrer);

var page = require('webpage').create();

// set our custom referer [sic]
page.customHeaders = {
	"Referer" : referrer
};

page.onLoadFinished = function(status){
	page.customHeaders = {};
	
	// get the currentUrl
	var currentUrl = page.evaluate(function() {
		return document.location.href;
	});
	
	// get the referrer
	var currentReferrer = page.evaluate(function() {
		return document.referrer;
	});
	
	
	console.log('Loading ' + currentUrl + ' finished with status: ' + status+'. document.referrer is: '+currentReferrer);

	// Only once do
	if ( page.firstLoad ) {
		page.firstLoad = false;

		console.log('Injecting the Link.');

		// Inject and Click a Link to our target
		page.evaluate(function (href) {
			// Create and append the link
			var link = document.createElement('a');
			link.setAttribute('href', href);
			document.body.appendChild(link);
			
			// Dispatch Click Event on the link
			var evt = document.createEvent('MouseEvents');
			evt.initMouseEvent('click', true, true, window, 1, 1, 1, 1, 1, false, false, false, false, 0, link);
			link.dispatchEvent(evt);
		}, targetUrl);
	} else {
		console.log('Exiting');
		phantom.exit();
	};
};

page.firstLoad = true;
page.open(referrer);

Use Settings:

var settings = {
  headers: {
   "Referer": "referer_url"
  }
};

And pass it as the second argument on function page.open, like that:

page.open(url, settings, function(status) {
...
});

how it will use?

`

page.onResourceRequested = function(r,n){

	page.customHeaders = {};

};

`
This is where the customHeaders should be cleared, and NOT in onLoadFinished because all elements called by that first page would still have the referer instead of the page itself.
And you can always put a condition to call it only once for neatness but I doubt there would be any performance improvement.
