ah you’re right in that Caddy isn’t gzip compressing the response, with Vary header removed I see
curl -Ik -H "Accept-Encoding: gzip" https://caddy.domain.com:4444/caddy-index.html
HTTP/1.1 200 OK

it’s working on Nginx via curl
curl -Ik -H "Accept-Encoding: gzip" https://ngx.domain.com/caddy-index.html

so my Caddyfile above with encode gzip isn’t working ?
