Loading policy file(s): loadPolicyFile flashvar?

Hello,

package blah.blah.blah {
	
	// Imports...
	
	dynamic public class Main extends MovieClip {
		
		public function Main() {
			
			addEventListener(Event.ADDED_TO_STAGE, init);
			
		}
		
		private function init(e:Event):void {
			
			removeEventListener(Event.ADDED_TO_STAGE, init);
			
			// This works:
			//flash.system.Security.loadPolicyFile('http://somdomain.com/crossdomain.xml');
			
			// This does not work:
			var paramObj:Object = LoaderInfo(this.root.loaderInfo).parameters;
			if (paramObj.policyFile != null) {
				flash.system.Security.loadPolicyFile(paramObj.policyFile.toString());
			}
			
			// ...
			// ...
			
		}
		
	}
	
}

Questions:

  1. Is it possible to load multiple policy files from differing domains? If so, could someone point me to some example code?
  2. How can I specify a policy file via a flashvar? In the above code, I have tried to load a policy via swfObject flashvars, but it does not load. Is this possible to do?

Optimally, I would like to be able to specify two different policy files, from different domains, via one flash variable.

At the very minimum, I would like to be able to load one policy file via a swfObject flashvar… Is there a good way to do this?

Thanks a billion in advance for the help!

Cheers,
Micky
