Flash to ASP.Net C#

Trying to post XML to an ASP.NET C# page and then write that XML as a file.

• Errors I kept receiving
  • "Root element is missing"
  • Before checking for the error - when trying to load the Request.InputStream, if I turned off the load and looked at what was recieved, I got "System.Web.HttpInputStream"
• Final Solutions
  • Request.InputStream.Position = 0; 

ACTIONSCRIPT CS3 

var respTxt:TextField = new TextField();
 var myTextFormat:TextFormat = new TextFormat();
 myTextFormat.size = 14;
 
 var xmlString:String = "<?xml version=\"1.0\" ?><root>Content passed from flash</root>";
 var sampleXml:XML = new XML(xmlString);
 
 var xmlResponse:XML;
 
 var xmlURLReq:URLRequest = new URLRequest("http://tonerpackaging.orbisdesign.net/include/xmlWrite.aspx");
 
 xmlURLReq.data = sampleXml;
 xmlURLReq.contentType = "text/xml";
 xmlURLReq.method = URLRequestMethod.POST;
 
 var xmlSendLoad:URLLoader = new URLLoader();
 xmlSendLoad.addEventListener(Event.COMPLETE, onComplete, false, 0, true);
 xmlSendLoad.addEventListener(IOErrorEvent.IO_ERROR, onIOError, false, 0, true);
 xmlSendLoad.load(xmlURLReq);
 
 function onComplete(evt:Event):void {
     try {
  xmlResponse = new XML(evt.target.data);
  respTxt.text = xmlResponse;
  removeEventListener(Event.COMPLETE, onComplete);
  removeEventListener(IOErrorEvent.IO_ERROR, onIOError);
     } catch (err:TypeError) {
  respTxt.text = "An error occured when communicating with server:\n" + err.message;
     }
     placeText();
 }
 
 function onIOError(evt:IOErrorEvent):void {
     respTxt.text = "An error occurred when attempting to load the XML.\n" + evt.text;
     placeText();
 }
 
 function placeText():void {
     respTxt.x = 15;
     respTxt.y = 15;
     respTxt.multiline = true;
     respTxt.autoSize = TextFieldAutoSize.LEFT;
     respTxt.setTextFormat(myTextFormat);
     addChild(respTxt);
