title: Determine unique visitors to site
body: <p>I'm creating a django website with Apache2 as the server. I need a way to determine the number of unique visitors to my website (specifically to every page in particular) in a full proof way. Unfortunately users will have high incentives to try to "game" the tracking systems so I'm trying to make it full proof. </p>
  
  <p>Is there any way of doing this? </p>
  
  <p>Currently I'm trying to use IP &amp; Cookies to determine unique visitors, but this system can be easily fooled with a headless browser.</p>
