압축을 지원하지 않는 원본일 경우 Proxy에서 압축

압축을 지원하지 않는 org3 구성

 

server {
    listen       80;
    server_name  org3.t.skcdn.com org3 ;

    access_log  /var/log/nginx/org3.log  my_log;
    add_header Cache-Control 'max-age=120';


    location / {
      root   /usr/share/nginx/html/;
    }
}

 

 

relay에 압축설정 및 org3으로 upstream구성

 # gzip config
    gzip on;
    gzip_types application/vnd.apple.mpegurl text/plain text/css application/json application/x-javascript text/javascript;
    gzip_min_length 100;
    gzip_http_version 1.1;
    gzip_buffers      16 8k;
    gzip_comp_level   4;
    gzip_static on;
 # brotli config
    brotli on;
    brotli_static on;
    brotli_comp_level  11;
    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;
	
   location / {
   proxy_pass http://org3;
 }

 

 

(테스트) 원본은 압축을 지원하지 않으나 relay에서 압축해 client에 전달, 응답은 Plain, Cachekey는 gzip으로 저장됨
