  //same attribute than the session middleware http://www.senchalabs.org/connect/middleware-session.html

  sio.set("authorization", passportSocketIo.authorize({
    key:    'express.sid',       //the cookie where express (or connect) stores its session id.

    fail: function(data, accept) {     // *optional* callbacks on success or fail
