Nginx store

在反向代理上做静态文件加速，不用到主服务器上面查询文件：

        location ~ "\.(swf|js|ico|gif|jpg|png|css|html|htm)$" {
            root /var/cache/nginx/$host;
            set $original_uri $uri;
            error_page 404 = /fetch;
        }
        location /fetch {
            internal;
            proxy_pass http://202.101.000.111:80;
            proxy_store /var/cache/nginx/$host${original_uri};
            proxy_store_access user:rw group:rw all:rw;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
        }
