Lighttpd

One solution: content negotiation using lua

Are you preparing your brotli-compressed files offline, or are you asking if lighttpd will compress to brotli dynamically? Patches submitted will be reviewed if you'd like to contribute.

I think I'm asking if lighttpd will compress to brotli dynamically. As for the content negotiation using lua, how would I implement that solution, is there a tutorial or document on it?

You obviously did not read the linked documentation to which you were pointed before you posted.

The upcoming lighttpd 1.4.56 (not yet released) supports dynamic brotli compression in mod_deflate when lighttpd collects the response (lighttpd default behavior) before sending to client. mod_deflate does not support dynamic compression which streaming partial responses in separate pieces.
