title: Re-route all requests to index.php with request as query string (.htaccess)
body: <p>I'm writing my very first .htaccess file and although I've learnt a lot already I have one thing that I'm struggling with.</p>
  
  <p>I have a CMS that generates pages based upon a variable called "filename" that's passed through my URL for example... index.php?filename=about.htm</p>
  
  <p>So I only have one real file... index.php</p>
  
  <p>I would like "index.php?filename" to not appear so all URL's look normal like www.example.com/about.htm even though the "filename" query string is still being passed.</p>
  
  <p>I hope I've made sense and this is possible... Thanks guys!</p>
