How to "prefer" brotli over gzip?

[shot]

I've read the docs regarding compression, and it states...

@Traefik docs

...the compression method choice rely (among other things) on the request's Accept-Encoding header.

...but it doesn't stipulate the actual criteria that determine which compression method is used. Both gzip and brotli are present in the Accept-Encoding header of the request, but Traefik always uses gzip.

Is there a way to force it to use brotli? Might it have to do with the order in which they appear? Do I need to rewrite the header with brotli first?

Thanks for any info or insights.

Hi @shot, thanks for your interest in Traefik!

What version of Traefik do you use?

Brotli is supported from Traefik v3 on.

Traefik v2 supports gzip but not brotli.

If in v3, a header contains both, brotli and gzip, Traefik will preference brotli over gzip.

@svx

Traefik v2 supports gzip but not brotli.

Oh, I'm using 2.10.4. I assumed the docs (which state that brotli is supported) pertained to the latest stable release. I guess that explains it. Thanks much!
