I've been using webalizer stats for a while now and I've always understood the referrers list to be the origin of the visitor to my site, i.e. if it says http://www.example.com then the visitor has come from that site whether it be a search engine or a site linking to me.
However recently I've been looking at purchasing another site and their webalizer referral stats confuse me. In their list of referrals it lists URLs from their own site? How can this be?
