Is there a difference in the behavior of EventListner between placing it on a server and hitting html directly?

<embed src="swfPlayer.swf" width="300" height="500" FlashVars="file=test.swf">

private function_load():void
{
  :
varfv:Object=LoaderInfo(this.root.loaderInfo).parameters;
var file: String = String(fv["file"]);

var loader: Loader = new Loader;
varurl —URLRequest=newURLRequest(file);
loader.load(url);

loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete);
  :
}

private function onComplete (event:Event): void
{
    Log.t("complete");

    var loaderInfo: LoaderInfo=event.target as LoaderInfo;
    var content —MovieClip = loaderInfo.content as MovieClip;
    addChildAt(content,0);

    Log.t("complete-end";
}
