Newer browsers block analytics providers from loading unless they adhere to the 'do not track' policy. In order to comply, we detect wether or not a visitor is requesting not to be tracked. If he is, we do not record or display his IP number. We also do not write any persistent cookies in his browser.
As a result, for these particular users, we do not display the IP number, nor do we show whether the visitor is a first time or return visitor. All other tracking information is provided.
The alternative would be non-compliance, resulting in Web-Stat being blocked from loading in the visitor's browser and therefore not being able to record any information at all.
