Is the cookie part of the proxy?

Question

HTTP Cookies

Hello network engineers!
We have a slight mismatch of information, my colleague claims that: "coockie is part of a proxy" and that "coockie is a kind of proxy". I affirm that cookies are site add-ons, and a proxy is an additional gateway between me and the rest of the world, and all these are different concepts, and even without going into the details of how this all works, my colleague's theories are a little wrong. Of course, we googled and everything says that I'm right and cookies are not a kind of proxy, but they don't believe me. Connoisseurs, judge our dispute

Answer 1

You are right.
