Set-Cookie headers not proxied back

[jcorbett-sweater]

I can pass headers from the client to the proxied endpoint, but headers are not proxied back. In particular set-cookie headers are not proxied back making any authentication graphql broke.

Only cookie based authorization patterns will be broken. If your auth depends on mutation return auth token to pass in future request's header, it will still work.

This is a new feature request.
