title: How to count requests to file
body: <p>Like, I have file on ftp <a href="http://site.com/download/file.zip" rel="nofollow">http://site.com/download/file.zip</a></p>
  
  <p>I download it by directly request from browser's address tab.</p>
  
  <p>How can I count the number of requests of this file?</p>
  
  <p>Or how do I remove the ability of such requests, so they should work only by php?</p>
