I have installed Webalizer Win32 for IIS and my win 2003 server which is working fine on the logs but for one part.
It is not showing the Referrers in the stats.

Does anyone know what option to set to allow the Referrers to show and be pulled from the logfiles on Windows IIS ?

I saw this below from the Webalizer website but it only gives info about Apache.
Any tips and info about this would be great. I can't seem to find the answer so far

The Webalizer doesn't show me Referrers or User Agents?

In order for the Webalizer to produce statistics for user agents (browsers) and referrers, that information needs to be in the log files produced by the web server. Most servers by default only produce CLF logs, which do not include the extra information. The way you have your server include this information depends on what server you are running. For apache, you need to edit the httpd.conf file (in the servers /conf directory) and...
For apache 1.2, add the line:

LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-agent}i\""

For apache 1.3, use the line:
CustomLog /var/lib/httpd/logs/access_log combined

Other servers are similar. Refer to your servers documentation for additional information on how to enable referrers and user agents.
