什么会导致SecurityErrorEvent？

Question

我正在执行以下命令：

var chatRequest:URLRequest = new URLRequest("http://test.com/videophonetest/scripts/get_put_peerID.php?peerID=" + myID);
                chatLoader = new URLLoader(chatRequest);
                configureListenersChatLoader(chatLoader);
                chatLoader.dataFormat = URLLoaderDataFormat.VARIABLES;
                chatLoader.load(chatRequest);

configureListenersChatLoader(chatLoader)和朋友看起来像这样：

private function configureListenersDeleteLoader(dispatcher:IEventDispatcher):void {
                dispatcher.addEventListener(Event.COMPLETE, completeHandlerDeleteLoader);
                dispatcher.addEventListener(Event.OPEN, openHandler);
                dispatcher.addEventListener(ProgressEvent.PROGRESS, progressHandler);
                dispatcher.addEventListener(SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler);
                dispatcher.addEventListener(HTTPStatusEvent.HTTP_STATUS, httpStatusHandler);
                dispatcher.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);
            }


            private function completeHandlerChatLoader(event:Event):void {              
                writeText("Completed Connection!");
                var urlVariables:URLVariables = new URLVariables(chatLoader.data);
                writeText("Your ID: " + myID);
                theirID = urlVariables.peerID;
                writeText("Their ID: " + theirID);          
            }
            private function completeHandlerDeleteLoader(event:Event):void {                
                writeText("Deletion Complete!");
                var urlVariables:URLVariables = new URLVariables(deleteLoader.data);
                writeText("Deleted: " + urlVariables.deleted);
                writeText("Getting New Chat...");
                initNewChatSession();               
            }

            private function openHandler(event:Event):void {
                writeText("openHandler: " + event);
            }

            private function progressHandler(event:ProgressEvent):void {
                writeText("progressHandler loaded:" + event.bytesLoaded + " total: " + event.bytesTotal);
            }

            private function securityErrorHandler(event:SecurityErrorEvent):void {
                writeText("securityErrorHandler: " + event);
            }

            private function httpStatusHandler(event:HTTPStatusEvent):void {
                writeText("httpStatusHandler: " + event);
            }

            private function ioErrorHandler(event:IOErrorEvent):void {
                writeText("ioErrorHandler: " + event);
            }

该命令在我的计算机上有效，但当我在我的室友计算机上尝试它时，它返回一个错误：

httpStatusHandler: [HTTPStatusEvent type="httpStatus" bubbles=false cancelable=false eventPhase=2 status=0 responseURL=null]

securityErrorHandler: [SecurityErrorEvent type="securityError" bubbles=false cancelable=false eventPhase=2 text="Error #2048"]

有可能发生这种情况的原因吗？它可以在一些电脑上运行，但不能在其他电脑上运行。防火墙？

您需要在此设置管理器中允许朋友的计算机上的文件位置：
