WebSocket requests not containing cookies or partial

[Mis1eader-dev]

Expected Behavior

One issue I have always had with WebSockets has been requests not sending cookies, or sending only 1 cookie.

In my case, a backend hosted on 127.0.0.1, the cookie header looks like this:

cookie: null;

However, that very same backend hosted on an external domain the cookie header will only send 1 cookie, and forgets about the rest of the cookies that match the cookie path:

cookie: a=1;

In the browser both scenarios work fine and 2 cookies are always sent reliably.

Actual Behavior

Sending null as a cookie value, or only sending 1 cookie, depending on the hostname.
