How to rewrite set-cookie path?

Traefik Traefik v2 (latest)

Hi,
Is is possible to set prefix to response header set-cookie path?

I'm trying to do reverse proxy with Traefik, so that path /server_X/whatever is routed to server_X. I need servers not be aware of this, so we strip path prefix, so server see request on /whatever. The issue is, when the server set cookies with request path, it's set to /whatever, which is not correct as browser is on /server_X/whatever, thus does not use this cookie. I can't use /, because servers use same cookies, so they would rewrite them all the time under their hands.

I need Traefik to rewrite response header set-cookie path to prefix it with /server_X. Is it possible? I'm able to do it with Nginx and HAProxy, but so far unlucky with Traefik. I found this feature request https://github.com/containous/traefik/issues/6047 that looks like it could help, but no progress there.

Thanks in advance

We have a similar requirement where we'd like to make the cookies SameSite=None . However the "Headers" Plugin seems only to help to replace cookies. Any idea on this? We want to make our backend application able to be served as an iframe without modifying the backend itself.
Maybe https://github.com/tomMoulard/htransformation could help but that seems "early stage of dev"?
