URLLoader IO error

Hi All,

I want to get information about internet connection using flash code. So that i am loading an xml from server onEnterFrame. And if the internet connection is lost then the URLLoader should give an IO error.

To handle the onErnterFrame event i am using the following function :

function onEnterFrameHandler(event:Event):void
{
      _connection_Status_XML_Loader = new URLLoader();  
      _connection_Status_XML_Loader.addEventListener(IOErrorEvent.IO_ERROR, connectionErrorHandler);
      _connection_Status_XML_Loader.addEventListener(HTTPStatusEvent.HTTP_STATUS, connectionHttpStatusHandler);
      _connection_Status_XML_Loader.addEventListener(Event.COMPLETE,connectionStatusHandler);
      var request:URLRequest = new URLRequest(serverPath+"abc.xml"+ "?"+Math.random());
     try

     {   
          _connection_Status_XML_Loader.load(request);
     }

     catch (error:Error)
     {   
           trace("Unable to load requested document");
     }
}

Normally, if i run the application in flash player then i will mostly got the message as

"Error opening URL 'http://servername/abc.xml?0.1506041861139238'"

several time becous i am trying to load xml in onEnterFrame. But in between sometime i got error message as :

Error #2044: Unhandled ioError:. text=Error #2032: Stream Error. URL: http://servername/abc.xml?0.2708006724715233
at ConnectionTest/onEnterFrameHandler()

Can anyone guide me ?

Thanks in Advance.
