How to set cookies in socket.io?

Question

Node.js

I'm trying to set up authentication through socket.io. I ran into a problem that cookies can be obtained upon connection (handshake.headers), but it is not clear how to set the identifier in response to an empty value. The stackoverflow bikes suggest setting cookies on the client, but that doesn't allow you to set the required httpOnly flag. How is it properly done?

Answer 1

Can set cookies via http, before handshake in response to any request
