Set up a Site Profile for each website you will be using with Xlogan.
The Site Profile tells Xlogan which domain names the site uses. This stops Xlogan from filling up your Referrers list with referrers from your own website.
You don't need to enter "www" at the beginning of the website name. For example, if your website is www.axeuk.com then you should enter axeuk.com.
If your log file contains information about multiple websites - i.e. if you use the same web hosting account to host different domain names - you should tick the "Show separate domains in the Files report" option. The Files report will then show "example.com/index.htm" and "example2.com/index.htm" separately, instead of just "/index.htm".
