Wicket-Atmosphere : best way to call server

Good afternoon,

When using Wicket-Atmosphere (0.11), which is the recommended way to send a
message to the server in order to receive a WebSocket (or fallback
transport) response?

I mean, I am supposed to do:

var socket = $.atmosphere;var request = new
$.atmosphere.AtmosphereRequest();var subSocket =
socket.subscribe(request);
subSocket.push(JSON.stringify({ 'blah' }));

Or:

Wicket.Ajax.get()

I doubt that there is a sensible performance difference, but I prefer to
ask.

Sorry if this is a silly question.

Regards,

Pierre
