title: (Almost) empty index.html file
body: <p>When using a almost empty file named <code>index.html</code> in my apache directories in order to avoid directory listings (e.g. /image folder), what is the minimum content of this file? Can it be empty, or should I include something like:</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;&lt;title&gt;&lt;/title&gt;
  </code></pre>
  
  <p>or</p>
  
  <pre><code>&lt;!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"&gt;
  &lt;html&gt;
  &lt;head&gt;
  &lt;title&gt;&lt;/title&gt;
  &lt;/head&gt;
  &lt;body&gt;
  &amp;npsp;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>or something in between?</p>
