Many thanks Henrik! I have add these two directive in apache2.conf: LogFormat "%{X-Forwarded-For}i %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" reverse_proxy and SetEnvIf X-Forwarded-For "^.*\..*\..*\..*" is-forwarder And in my vhost: CustomLog /var/log/apache2/blog.log reverse_proxy env=is-forwarder CustomLog /var/log/apache2/blog.log combined env=!is-forwarder This works pretty fine.
