var session = {

    secret: "secret",
    key: "mykey.sid",
    cookieParser: connect.cookieParser("secret")
};

io.use(socketSession(session));

io.on("connection", function(socket){

    socket.on("whoAreYou", function(callback){
        
        //read from session
        callback(socket.session.name);
    });
    
    socket.on("setName", function(data) {
        
        //write to session
        socket.session.name = data.name;
    })
});

Client

socket.emit("setName", { name: "hans" });

socket.emit("whoAreYou", function(name) { 
    console.log("I am " + name); 
});


//=> I am hans

Notes

Make sure to fire a http request to initialize the session/cookie before accessing the session with socket.io. If you are serving the socket.io client with your node.js server this won't be a problem for you.
