location 设定某个文件的过期时间，并不记录访问日志

网页的根目录本来是: 6 root /app/www/default;

 [root@web01 default]# cat /app/server/nginx/conf/vhosts/default.conf
 server {
         listen       ;
         server_name  espressos.cn;
     index index.php index.htm index.html;
     root /app/www/default;
     location ~ .*\.(sh|bash)?$
     {
         return ;
     }
 #    if (!-e $request_filename) {
 #        rewrite ^/(.*)$ /index.php last;
 #        }
     location ~ .*\.(php|php5)?$
     {
         #fastcgi_pass  unix:/tmp/php-cgi.sock;
         fastcgi_pass  127.0.0.1:;
         fastcgi_index index.php;
         include fastcgi.conf;
     }
     location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
     {
         expires 30d;
     }
     location ~ .*\.(js|css)?$
     {
         expires 1h;
     }
     include /app/server/nginx/conf/rewrite/default.conf;
     access_log  /app/log/nginx/access/default.log;
 }

参数：access_log off ------->关闭了记录这个页面的到访问日志里！！！默认是记录访问日志的。
