   The server comes with a built-in list of active modules.  This
   directive clears the list.  It is assumed that the list will then be
   re-populated using the <A HREF="#addmodule">AddModule</A> directive.<p><hr>

  +<!--%plaintext &lt;?INDEX {\tt ContentDigest} directive&gt; -->
  +<strong>Syntax:</strong> ContentDigest <em>on|off</em><br>
  +<strong>Default:</strong> <code>ContentDigest off</code><br>
  +<strong>Context:</strong> any<br>
  +<strong>Override:</strong> AuthConfig<br>
  +<strong>Status:</strong> experimental<p>
  +<strong>Compatibility:</strong> ContentDigest is only available in Apache 1.1
and later<p>
  +This directive enables the generation of <code>Content-MD5</code> headers
  +as defined in RFC1864 respectively RFC2068.<P>
  +MD5 is an algorithm for computing a "message digest" (sometimes called
  +"fingerprint") of arbitrary-length data, with a high degree of confidence
  +that any alterations in the data will be reflected in alterations in the
  +message digest.<P>
  +The <code>Content-MD5</code> header provides an end-to-end message
  +integrity check (MIC) of the entity-body. A proxy or client may check this
  +header for detecting accidental modification of the entity-body
  +in transit.
  +Example header:
  +<pre>   Content-MD5: AuLb7Dp1rqtRtxz2m9kRpA==</pre><P>
  +Note that this can cause performance problems on your server
  +since the message digest is computed on every request
  +(the values are not cached).
