我使用的是Debian 8，Nginx 1.10，服务器Apache2。 我的Nginxconfiguration是：
proxy_cache_path /tmp/nginx levels=1:2 keys_zone=my_zone:10m inactive=60m; proxy_cache_key "$scheme$request_method$host$request_uri"; server { .... location ~* \.(?:jpg|jpeg|gif|png|ico|cur|gz|svg|svgz|mp4|ogg|ogv|webm|htc|css|js)$ { proxy_cache my_zone; expires 24h; add_header Cache-Control "public"; proxy_pass http://*******.com; proxy_cache_bypass $http_cache_control; add_header X-Proxy-Cache $upstream_cache_status; } } 而CURL的结果是： curl -X GET -I http://******/test.png
HTTP/1.1 200 OK Server: nginx/1.10.3 Date: Sat, 22 Jul 2017 01:55:56 GMT Content-Type: image/png Content-Length: 28847 Connection: keep-alive Last-Modified: Fri, 21 Jul 2017 06:10:10 GMT Vary: Accept-Encoding Expires: Sun, 23 Jul 2017 01:55:56 GMT Cache-Control: max-age=86400 Cache-Control: public X-Proxy-Cache: MISS Accept-Ranges: bytes
有没有丢失的configuration？
感谢您的任何build议！
