Good news everyone!

I bumped SockJS-protocol to 0.3.3. SockJS-node and SockJS-erlang were updated as well.

SockJS-client is not updated on this release.

There is only one significant change in the server code - workaround for iOS6 POST caching “feature”.

The protocol change is pretty straightforward - we now need to send proper no-cache headers for all the POST urls. Protocol change: https://github.com/sockjs/sockjs-protocol/commit/3630b4c199ab2e8738f978ac2004b3d8bb6c3c29

Relevant discussions: https://github.com/sockjs/sockjs-protocol/issues/56 https://github.com/sockjs/sockjs-node/pull/88

Thanks to David Glasser from Meteor for proposing a fix.

Cheers, Marek

看 Github 上的源代码说的是提供了一个模仿 websocket 的 Object, 然后还提供了多种语言, ruby, python, lua, python 等绑定… https://github.com/sockjs/sockjs-client

好奇一下, 这样的话这个适合用来干嘛?
