title: Zeus server doesn't redirect on RewriteCond HTTP_USER_AGENT rule
body: <p>I can't get this redirect to function:</p>
  
  <pre><code>RewriteEngine on
  RewriteBase /
  RewriteCond %{HTTP_USER_AGENT} iPad|iPod|iPhone|Android|s+Mobile
  RewriteRule .* mobile.php
  </code></pre>
  
  <p>I'm testing it using my Android phone, and also using the user-agent switcher in Google Chrome dev version.</p>
  
  <p>I tried <code>AllowOverride All</code> but it makes the server, running Zeus, reply with an access denied message. </p>
  
  <p>It is a shared host and so I do not really have access to any server logs that I know about. </p>
