copied!<p>sberry2A is on the right track. Robert Penner recently showed us that <a href="http://gist.github.com/326911" rel="nofollow noreferrer">URLLoader is nothing but a tiny wrapper</a> around the native URLStream, so rolling your own URLLoader is a reasonable idea. </p> <p>This is how I roll: </p> <pre><code>public class URLLoader extends EventDispatcher{ private var _urlRequest:URLRequest; //the built-in URLLoader doesn't give you any access to the requested URL... private var _stream:URLStream; private var _dataFormat:String;// = "text" private var _data:*; private var _bytesLoaded:uint;// = 0 private var _bytesTotal:uint;// = 0 public function get request():URLRequest { return _urlRequest;} public function get fileName():String { return _urlRequest.url.match(/(?:\\|\/)([^\\\/]*)$/)[1];} public function get dataFormat():String { return _dataFormat;} public function get data():* { return _data; } public function get bytesLoaded():uint { return _bytesLoaded; } public function get bytesTotal():uint { return _bytesTotal; } public function URLLoader(request:URLRequest = null){ super(); _stream = new URLStream(); _stream.addEventListener(Event.OPEN, openHandler); _stream.addEventListener(ProgressEvent.PROGRESS, progressHandler); _stream.addEventListener(Event.COMPLETE, completeHandler); _stream.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler); _stream.addEventListener(SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler); _stream.addEventListener(HTTPStatusEvent.HTTP_STATUS, httpStatusHandler); if (request != null){ load(request); }; } public function load(request:URLRequest):void { _urlRequest = request; _stream.load(_urlRequest); } public function close():void{ _stream.close(); } private function progressHandler(event:ProgressEvent):void { _bytesLoaded = event.bytesLoaded; _bytesTotal = event.bytesTotal; dispatchEvent(event); } private function completeHandler(event:Event):void{ var bytes:ByteArray = new ByteArray(); _stream.readBytes(bytes); switch (_dataFormat){ case "binary": _data = bytes; break; case "variables": if (bytes.length > 0){ _data = new URLVariables(bytes.toString()); break; }; case "text": default: _data = bytes.toString(); break; }; trace("URLLoader: (" + fileName + "): " + event.type); dispatchEvent(event); } private function openHandler(event:Event):void { trace("URLLoader: ("+fileName+"): " + event.type +" "+_urlRequest.url); dispatchEvent(event); } private function securityErrorHandler(event:SecurityErrorEvent):void { trace("URLLoader ("+fileName+"): " + event.type + " - " + event.text); dispatchEvent(event); } private function httpStatusHandler(event:HTTPStatusEvent):void { dispatchEvent(event); } private function ioErrorHandler(event:IOErrorEvent):void { trace("URLLoader ("+fileName+"): " + event.type + " - " + event.text); dispatchEvent(event); } } </code></pre> <p>Notice the request and fileName properties. To get the URLRequest from the COMPLETE-event handler, you simply do: <code>var req:URLRequest = URLLoader(evtObj.target).request;</code> </p>
