Nginx 用最快方式让缓存失效

proxy_cache_path /data/nginx/tmpcache levels=2:2 keys_zone=two:10m loader_threshold=300 
                     loader_files=200 max_size=200m inactive=1m;

server {
    server_name shop**.com.cn;
　　listen : 8080;
    root html/;
    error_log logs/cacherr.log debug;

    location ~ /purge(/.*) {
            proxy_cache_purge two $scheme$1; #这个第三方模块key必须与下面的location 里的 proxy_cache_key一致，用于实时清除下面的key缓存
        }   

    location /{
        proxy_cache two;
        proxy_cache_valid 200 1m;
        add_header X-Cache-Status $upstream_cache_status;

        proxy_cache_key $scheme$uri;
        proxy_pass http://localhost:8012;
    }
