The purpose of this lab is to demonstrate the ability to configure Apache to use rotating log files.

<ol id="main" class="count">
<? // 1. ?>
<li class="count">Setup a directory for use in <?=$evaluationType?> <?=$evaluationNumber?>.

<li class="count">Create a directory called <b class="copyText"><?=$evaluationName?></b> inside your <b><?=$dataFolder?><?=$dirSep?><?=$courseNumber?></b> directory.</li>

Configure Apache so we can throw an error.
<br>It turns out that Apache 2.4 no longer considers '404 Not Found.' as an error, so we need to do it another way.
<br>Setup a folder that is not-browsable.
<ol>
<li>Create the directory <b class="copyText">missing</b> inside the <b><?=$dataFolder?><?=$dirSep?><?=$courseNumber?><?=$dirSep?><?=$evaluationName?></b> directory.</li>
<li>Open your <b>lab09.test.conf</b> file in an editor.</li>
<li>Copy this Directory configuration below the one you have for <b><?=$apacheFolder?>/<?=$courseNumber?>/<?=$evaluationName?></b>:
