-I'm trying to decide whether this example is worthwhile to keep, and, if
-so, whether it needs to be updated/rewritten. Certainly the description
-needs to be rewritten. I'm not sure we really need to be recommending

-    <dt>Description:</dt>
-
-    <dd>
-      <p>Wouldn't it be nice, while creating a complex web page, if
-      the web browser would automatically refresh the page every
-      time we save a new version from within our editor?
-      Impossible?</p>
-    </dd>
-
-    <dt>Solution:</dt>
-
-    <dd>
-      <p>No! We just combine the MIME multipart feature, the
-      web server NPH feature, and the URL manipulation power of
-      <module>mod_rewrite</module>. First, we establish a new
-      URL feature: Adding just <code>:refresh</code> to any
-      URL causes the 'page' to be refreshed every time it is
-      updated on the filesystem.</p>
-
-<highlight language="config">
-RewriteRule   ^(/[uge]/[^/]+/?.*):refresh  /internal/cgi/apache/nph-refresh?f=$1
-</highlight>
-
-      <p>Now when we reference the URL</p>
-
-<example>
-/u/foo/bar/page.html:refresh
-</example>
-
-      <p>this leads to the internal invocation of the URL</p>
-
-<example>
-/internal/cgi/apache/nph-refresh?f=/u/foo/bar/page.html
-</example>
-
-      <p>The only missing part is the NPH-CGI script. Although
-      one would usually say "left as an exercise to the reader"
-      ;-) I will provide this, too.</p>
