Hi all,

This patch adds a module for dynamic Brotli (RFC 7932) compression in httpd.

The new compression format is supported by Mozilla Firefox since 44.0 and
by Google Chrome since 50.0 [1, 2], and both nginx and IIS have modules that
offer Brotli compression.

With the new module, existing mod_deflate installations can benefit from
better compression ratio by sending Brotli-compressed data to the clients
that support it:

   LoadModule brotli_module modules/
   LoadModule deflate_module modules/

sounds good - 20% better compression AFAIK

how is the ordering?
defined by SetOutputFilter or client?

looked at my firefox request headers and "br" is at the last position
Accept-Encoding: gzip, deflate, br

does it also support (%{ratio_info}n%%) in the log configuration?

LogFormat "%a %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" (%{ratio_info}n%%)" combined

leads to: - - [16/Sep/2016:15:13:28 +0200] "GET / HTTP/1.1" 200 4133 "" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_8) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.112 Safari/537.36" (38%)

would especially when you compare clients with and without support nice to see the difference here
