- <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
- <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code>. 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>
-
-<pre class="prettyprint lang-config">RewriteRule ^(/[uge]/[^/]+/?.*):refresh /internal/cgi/apache/nph-refresh?f=$1</pre>
-
-
- <p>Now when we reference the URL</p>
-
-<div class="example"><p><code>
-/u/foo/bar/page.html:refresh
-</code></p></div>
-
- <p>this leads to the internal invocation of the URL</p>
-
-<div class="example"><p><code>
-/internal/cgi/apache/nph-refresh?f=/u/foo/bar/page.html
-</code></p></div>
-
- <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>
