Nginx 代理缓存 proxy_cache 与缓存控制实践

缓存路径与共享区：proxy_cache_path /var/cache/nginx levels=1:2 keys_zone=STATIC:10m inactive=7d max_size=1g;

站点缓存策略：server {

listen 80;

server_name static.example.com;

location /assets/ {

proxy_cache STATIC;

proxy_cache_valid 200 301 302 10m;

proxy_cache_valid 404 1m;

add_header X-Cache $upstream_cache_status;

proxy_pass http://backend_static;

}

location /api/ {

proxy_no_cache $http_authorization;

proxy_cache_bypass $http_authorization;

proxy_pass http://backend_api;

}

}
