        request = new URLRequest("http://localhost/index.php");
        request.method = URLRequestMethod.POST;

        variables = new URLVariables();
        variables.uid = uid;
        request.data = variables;

        loader = new URLLoader();
        loader.dataFormat = URLLoaderDataFormat.VARIABLES;
        loader.addEventListener(Event.COMPLETE, urlLoader_existsHandler);
        loader.load(request);
    }

    protected function urlLoader_existsHandler(event:Event):void {
        trace(event);
        //var variables:URLVariables = URLLoader(event.target).data;
        //trace(variables);
        //trace(variables.success);
