Apache和Nginx开启访问日志但不记录图片css等的方法

nginx下，可以和缓存时间一起设置log_format  access  '$remote_addr - $remote_user [$time_local] "$request" '
              '$status $body_bytes_sent "$http_referer" '
              '"$http_user_agent" $http_x_forwarded_for';
   location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
    {
        expires      30d;
        access_log off;
    }
    location ~ .*\.(js|css)?$
    {
        expires      1d;
        access_log off;
    }
    access_log  /www/logs/9enjoy.com.log access;
apache下两种方式：
1.只记录html,htm,php等文件SetEnvIfNoCase Request_URI "(\.htm|\/|\.html|\.php)$" htm
CustomLog logs/9enjoy.com-access_log combined env=htm2.排除法：<FilesMatch “\.(ico|gif|jpg|png|bmp|swf|js|css)”>
SetEnv IMAGE 1
</FilesMatch>
CustomLog logs/9enjoy.com-access_log combined env=!IMAGE
