Can Caddy V1 apply GZIP compression to a proxied response?

Question

I'm running Caddy v1 as a reverse proxy and I would like to apply GZIP compression on e.g. JSON responses.

I noticed that the gzip Caddy v1 directive only applies on files Caddy serves its self but not on responses where Caddy runs a reverse proxy with the proxy directive.

0.0.0.0:8080 {
    gzip {
      ext *
      level 9
    }
    log stdout
    errors stdout

    proxy /api/v2 127.0.0.1:50010 {
          transparent
          without /api/v2
    }
}

Is there a way to compress the proxied response body or is this not possible with Caddy?

Due to the fact that there is Caddy v2 and Caddy v1 is not anymore supported this question can be considered as obsolete. GZIP in V2 works as expected – Bainter
