Send cookies with socket.io-client

I am trying to connect to a websocket. I would like to add cookies from the actual website login, so the server (which is NOT mine), knows who I am (events are account specific).

var opts = {
   extraHeaders: {
        'Cookie': "_ga=GA1.2.17432343994.1475611967; _gat=1; __cfduid=dc232334gwdsd23434542342342342475611928'
    },
}

function socket() {
            var socket = io(websiteURL, opts);
            var patch = require('socketio-wildcard')(io.Manager); patch(socket);

            socket.on('connect', function () {
                console.log(" > [Connected]");

            });
            socket.on('*', function (data) {                
                console.log(" >>> " + data.);
            });

            socket.on('disconnect', function () {
                console.log(" > [Disconnected]");
            });

}

The connection itself works fine, since I am receiving the public events from the website (not per-account ones).

I tried to find the problem using node-inspector.

This is the first request that is being done. It seems like the request headers are empty and the cookies are missing from there.

(Yes, I am sending less cookies in node, just to see if they pop up in the request cookies)

Am I doing something wrong? How would I add cookies the right way?
