From 44c1d726d18760cd9e9da670fcc90c4902a9eee4 Mon Sep 17 00:00:00 2001 From: Evgeny Kotkov Date: Wed, 21 Sep 2016 10:38:48 +0000 Subject: mod_brotli: Add initial implementation. This new module supports dynamic Brotli (RFC 7932) compression. Existing mod_deflate installations can benefit from better compression ratio by sending Brotli-compressed data to the clients that support it: SetOutputFilter BROTLI_COMPRESS;DEFLATE The module features zero-copy processing, which is only possible with the new API from the upcoming 1.0.x series of brotli [1]. The Linux makefile works against libbrotli [2], as currently the core brotli repository doesn't offer a way to build a library [3]. Apart from that, only the CMake build is now supported.
