checkPolicyFile flag was not set

Sometimes the uploading of crossdomain.xml file is not enough to get the things working.

I just released a site for my client. I uploaded all the stuff on the server including crossdomain.xml file, but the site didn't works with "www". The error that popups was:

A policy file is required, but the checkPolicyFile flag was not set when this media was loaded

So the solution is pass a LoaderContext to your Loader object:

var context:LoaderContext = new LoaderContext();
context.checkPolicyFile = true;
var loader:Loader = new Loader();
var img_url:String = img_src;
var request_url:URLRequest = new URLRequest(img_url);
loader.load(request_url, context);

checkPolicyFile flag was not set
