[Muosvr]

Goals

1. Add support for the partitioned attribute in cookies

Non-Goals

Background

Chrome has started to deprecate third party cookies, this leaves iframe application unable to persist state for purposes such as authentication. In order for iframe applications to continue to use cookies without requiring additional user interaction, they need to set the partitioned attribute on the cookie.

Proposal

Add partitioned attribute to ResponseCookie and the ability to set partitioned in Set-Cookie header

Seems like it exists if you set the cookie using the Next.js built in cookie function.
I seem to experience issues with my presumed third-party API which supplies me with token cookies though and I cannot seem to access the token cookies using the normal cookie function.
