사전압축할 파일을 모두 brotli 최대 압축 level 11로 사전압축한 파일을 생성한다.

 

# find . \( -iname '*.json' -o -iname '*.js' \) -exec bash -c 'brotli --best "$0"' {} \;

 

 

org.conf에 brotli_static on 설정을 한다.

    # brotli config
    brotli on;
    brotli_static on;
    brotli_comp_level  6;
    brotli_types application/vnd.apple.mpegurl text/plain text/css application/json application/x-javascript text/javascript;
    brotli_min_length 100;
    brotli_buffers   16 8k

 

Accept-encoding : br로 요청 시 Content-Encoding: br로 응답이 오고, Content-Length: 64로 나타남

# curl org/1.json -H "accept-encoding: br" -I

On-the-fley 압축과 다른점 Content-Length가 없고, ETag는 plain text값에 "W/" 추가됨, Transfer-encoding : chunked로 응답
