Contradiction in Developer Guide about what is instance?

Question

Hi!
On page 16 of developer guide it is said that the structure of URL is follows
protocol:[//host][:port]/appname/[instanceName]
But earlier on this page it was said that
The NetConnection class connects a client to an application instance on the server.
and an example was given
var nc:NetConnection = new NetConnection();
nc.connect("rtmp://localhost/HelloServer");
where the connect directive does not contain instance name.
So, how these relates? Does instance name is just omited in example meaning _definst_?
Is it possible to write
nc.connect("rtmp://localhost/HelloServer/room1");
Thanks.

Hi,
Your understanding is almost correct and there is no contradiction regarding the instance and URL in the Developer guide.
As it said, the net connection always connects to an instance of an application, this instance can be explicitly mentioned (as you wanted to add room1) or if it is not given, FMS uses a default instance with the identity _definst_ for all its purposes. You do not need to append this _definst_ in your connection URLs or elsewhere, but its what the connection goes to.
If you see the administration console for FMS, you can observe clearly what instance is getting the connections.
So, protocol:[//host][:port]/appname/[instanceName] is complete with explicit instance name in the URL.
The NetConnection class connects a client to an application instance on the server. : Correct
nc.connect("rtmp://localhost/HelloServer"); // it connects to _definst_
nc.connect("rtmp://localhost/HelloServer/room1"); // possible and connected to instance room1.
Hope it helps. Thank you !
