Referral

Understanding referrals

[wiuff]

How can the domaine be its own referral?

[nmattheij]

I'm not sure what you mean, but if you click a link to another page on your site/domain, technically the referral is your own site/domain.

It's also called "direct traffic".

Any items that you are including in your page like images, Javascript or Stylesheets, will also show the referer as the page in which they are being loaded.
