"minsize-res" was introduced in 3.2 I guess (and I'm using 3.1) but the default value being 0, it's not the issue here. What I do : $ curl -v --http1.1 --compressed https://example.com/ GET / HTTP/1.1 Host: example.com User-Agent: curl/7.76.1 Accept: */* Accept-Encoding: deflate, gzip HTTP/1.1 200 OK x-version: 20250331.2 cache-control: private, no-cache, no-store, max-age=0 content-type: text/html content-length: 3362 No compression here :( HAProxy config snippet : backend test [...] filter compression compression algo-res gzip compression type-res text/html acl static_content path_end .png .gif .css .js .svg .jpg .jpeg .ico .woff .woff2 .ttf .eot .otf .webp .pdf .webp .webm .weba http-request lua.myscript if !static_content If you have any clue, I'll be glad to perform more tests.
