csrf

I am trying to implement CSRF protection in an app built using node.js using the express.js framework. The app makes abundant use of Ajax post calls to the server. I understand that the connect framework provides CSRF middleware, but I am not sure how to implement it in the scope of client-side Ajax post requests.

There are bits and pieces about this in other Questions posted here in stackoverflow, but I have yet to find a reasonably complete example of how to implement it from both the client and server sides.

Does anyone have a working example they care to share?
