Specifically, are you referring to JWT with Apollo client on the server-side?
On the client-side, you can just use a link and get the cookie into an auth header that way. On the server-side, you need some way of getting that auth token from the cookie and passing it into the server-side runtime so that you can insert it into the auth header via a link in each server-side Apollo client instance.
