[users@httpd] ProxyPass and remote ip-addresses

Hi there,

I have a setup with 2 servers where the first one works as a proxy to
the second.
On my proxy server i have this in apache's config:

<VirtualHost *:80>
        ServerName www.hjemmesideteknik.dk
        ServerAlias hjemmesideteknik.dk
        ProxyPreserveHost On
        ProxyPass / http://192.168.1.106/
        ProxyPassReverse / http://192.168.1.106/
</VirtualHost>

and the proxy works fine and I can see the site from the internet. My
problem is that in the access log file for the site it puts my proxy's
IP-address in as the remote ip in stead of the original users ip.

How can I solve this so the users ip is written in the logfile?

This is normal behaviour: the backend server only sees a connection from the 
reverse proxy, since the original connection is terminated at the reverse proxy.

To solve this, see 
http://httpd.apache.org/docs/current/mod/mod_proxy.html#x-headers (the 
X-forwarded-for header).

Read the documentation for LogFormat:

http://httpd.apache.org/docs/current/mod/mod_log_config.html#logformat

It shows you how to log any variable apache knows about.
