I’ve been fussing with this a bit and am concluding that serving pre-compressed assets (for example, gzip via zopfli and brotli) isn’t something one shouldn’t be doing with Caddy 2 quite yet. Does that sound right?
I found threads on gzip and brotli, however in both cases I’m finding the solutions troublesome; Often the browsers want to download the content directly as though the content is application/octet-stream.
