How is Opa handling communication between client and server?

Is Opa using AJAX or Websockets? I'm guessing it would be the former. What if I want to use websockets inste开发者_JAVA百科ad of AJAX? Or is it similar to socket.io for Javascript - if the browser supports Websockets it uses them, otherwise it falls back to AJAX & Flash sockets.

OPA doesn't currently support websockets.

But it's something we considere again, since firefox 6 brings back support for websockets and a fix is proposed for the previous big security issue.

Opa is using AJAX currently.

Moreover, a think websocket is rarely supported (by browsers) for the moment due to security reason. And the RFC is still in draft.

Opa servers does not support websocket protocol for the moment.
