Socket.io doesn't set CORS header(s)

Question

I know this question has been asked a couple of times.
However, I can\'t get any those solutions to work.
I\'m running a standard install of node.js and socket.

Answer 1

This is the syntax I had to use to get CORS working with socket.io:

io.set( 'origins', '*domain.com*:*' );

If it comes to it, use console.log to make sure you're entering this block of code in Manager.prototype.handleHandshake inside ./lib/manager.js:

 if (origin) {
    // https://developer.mozilla.org/En/HTTP_Access_Control
    headers['Access-Control-Allow-Origin'] = '*';

    if (req.headers.cookie) {
      headers['Access-Control-Allow-Credentials'] = 'true';
    }
  }
