How is Opa handling communication between client and server?

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.

This is the nice thing about socket. Io, it hides the underlying details and uses websockets when its available - websockets being a bit faster than AJAX as I understand it. – aneccodeal Jul 10 at 18:02.

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.

AJAX is a bit of a kludge (though a very widely used Kluge). Websockets are much simpler and potentially faster. More browsers will be supporting websockets in the future.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
