How to load external swf with url parameter?

I want to load this url “http://www.testing.com/testing.swf?user=testing&site=tester&type=compact” into another swf.

I’ve tried this code but it is not working.

on (release) {
loader.loadMovie(“http://www.testing.com/testing.swf?user=testing&site=tester&type=compact”);

}

Can anybody help me?
