    Change in Behavior of NetStream in AIR 2 (GET to POST)


      I was all excited about the release of AIR 2 beta yesterday, with  the new socket support and improved h.264 encoding I was looking forward  to upgrading some applications . So I went and upgraded one of my  larger applications to AIR 2 to start the porting process since it would  benefit the most. Everything went well till I tried to play video from a  UPNP source, I was getting StreamNotFound errors. After a few hours of  debugging and reading the Beta documentation I tracked down the issue,  there was a change in behavior in how a request for videos over HTTP  occurs from a GET to a POST.

      I wasn't sure what this came from (AIR 2b or Flash 10.1b) but  wondered if anyone else noticed this small but significant change. I  guess my next step will be creating a bug in JIRA, just wanted to put it  out on the list.

      Here's the rundown:
      - Flex for both
      - Air  Versions: 1.5.2 vs 2.0B
      X-Flash-Versions: 10,0,32,18  vs 10,1,50,334

      Smallest Reproducible Code:

      protected function runTest() : void{
           var metaListener : Object = new Object();
          var netConn :  NetConnection = new NetConnection();
          // init the stream
           var stream : NetStream = new NetStream(netConn);
           stream.addEventListener(NetStatusEvent.NET_STATUS,  netStatusHandler);
          metaListener.onMetaData = theMeta;
           stream.client = metaListener;
          stream.play( <PUT SOME VIDEO  URL HERE> );

      protected function netStatusHandler( event : NetStatusEvent) :  void{
          trace("netStatusHandler: " + event.type + " " +  event.info.code);

      protected function  theMeta(data:Object):void {
           trace("Duration: " + data.duration + " Position: " +  data.moovposition);

      Example request from Apache Log:
