feat(qwik-city): append cookie headers to response

[mhuretski]

Overview

What is it?

• Feature / enhancement
• Bug
• Docs / tests / types / typos

Description

Qwik-city lacks ability to append cookie headers to response. See https://developer.mozilla.org/en-US/docs/Web/API/Headers/append

Use cases and why

In some cases it's valuable to be able to append cookies with the same name but different options.

MY_COOKIE=my_value; Expires=Mon, 28 May 2024 09:00:00 GMT; Path=/; Domain=my.domain.com
MY_COOKIE=my_value; Expires=Mon, 29 May 2024 10:00:00 GMT; Path=/account/; Domain=another.my.domain.com
MY_COOKIE=my_value; Expires=Mon, 30 May 2024 11:00:00 GMT; Path=/api/; Domain=.my.domain.com
