title: How to link to a random page?
body: <p>I want to link to a page selected randomly from all the html files in a directory.</p>
  
  <p>I have tried <a href="http://www.url.com/directory/?random" rel="nofollow">http://www.url.com/directory/?random</a> but only get a 404 error.</p>
  
  <p>Are there permissions that I need to change? What is the simplest way of doing this?</p>
