<h2><A name="contentdigest">ContentDigest directive</A></h2>

<!--%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).
