I'm trying to distinguish specifically between the 404 and 401 (or any) HTTP status codes, but the events raised by NetStream/NetConnect do not seem to include the HTTP status.

```
var url = "404_or_401_producing_url";

var _nc = new NetConnection(); 
_nc.connect(null);

var _ns = new NetStream(_nc);
_ns.play(url);

```

Is there an event or property available during this flow that includes the HTTP status?
