<li>Test the <code>Alias</code> and <code>Redirect</code> directives from <b><?=$evaluationNamePrevious?></b> using the <b>CST1611.test</b> host.
<ol>
<li>Open up a browser.</li>
<li>Test each <code>Alias</code> and <code>Redirect</code> using <b class="copyText">http://CST1611.test/<?=$evaluationNamePrevious?></b> as the starting URL.
<ol>
<li>Test the <b>aliasfrom</b> <code>Alias</code>.
<ol>
<li>Enter <b>CST1611.test</b> in the address bar and hit enter.</li>

<li>Test the <b>AliasFileFrom.txt</b> <code>Alias</code>.
<ol>
<li>Enter <b>CST1611.test</b> in the address bar and hit enter.</li>
<li>Click on <b><?=$evaluationNamePrevious?></b>. Click on <b>AliasFileFrom.txt</b>. Your browser should show the contents of the <b>AliasFileFrom.txt</b> file.<br>The <code>Alias</code> does not work.</li>

<li>Test the <b>ClassHome</b> <code>Redirect</code>.
<ol>
<li>Enter <b>CST1611.test</b> in the address bar and hit enter.</li>
<li>Click on <b><?=$evaluationNamePrevious?></b>. Click on <b>ClassHome</b>. You see the contents of the <b>ClassHome</b> directory.<br>The <code>Redirect</code> does not work.</li>

<li>Enter <b>CST1611.test</b> in the address bar and hit enter.</li>
<li>Click on <b><?=$evaluationNamePrevious?></b>. Click on <b>ClassFile.txt</b>. Your browser should now show the contents of the <b>ClassFile.txt</b> file.
<li>Now add a <b>/</b> to the end of the URL in the location bar and hit enter. You see a page not found error.<br>The <code>Redirect</code> does not work.</li>
</ol>

<li>Test the <b>redirected</b> <code>Redirect</code>.
<ol>
<li>Enter <b>CST1611.test</b> in the address bar and hit enter.</li>
<li>Click on <b><?=$evaluationNamePrevious?></b>. Click on <b>redirected</b>. You see the contents of the <b>redirected</b> directory.<br>The <code>Redirect</code> does not work.</li>

<li>Test the <b>fromnothing</b> <code>Redirect</code>.

<li>Enter <b>CST1611.test</b> in the address bar and hit enter.</li>
<li>Click on <b><?=$evaluationNamePrevious?></b>. Add <b>nothing</b> to the end of the URL in the location bar and hit enter. You see a page not found error. The <code>Redirect</code> does not work.</li>
<li>Go back a page and add <b>nothing/</b> (note the slash) to the end of the URL in the location bar and hit enter. You see a page not found error.<br>The <code>Redirect</code> does not work.</li>
</ol>

The short version is that <b>none</b> of the <code>Alias</code> and <code>Redirect</code> directives from <?=$evaluationNamePrevious?> should work.
This is because the URL-path does not match the new URL from the <b>CST1611.test</b> host.
If they do, then you did not follow the directions in <?=$evaluationNamePrevious?> as to where the directives should have been placed or did them incorrectly.
</ol>
</li>

<li>Copy and modify the <code>Alias</code> and <code>Redirect</code> directives from <b><?=$evaluationNamePrevious?></b> so they work with the <b>CST1611.test</b> host.
<ol>
<li>Copy the <b>localhost (000-default.conf)</b> Alias and Redirect directives to the <b>CST1611.test (cst1611.test.conf)</b> <code>VirtualHost</code>.
<ol>
<li>Open your <b>cst1611.test.conf</b> file in a text editor.</li>
<li>Below the <code></Directory></code> directive add the comment:<br>
<comm class="copyText"># <?=$evaluationType?> <?=$evaluationNumber?></comm></li>
<li>Copy all of the <code>Alias</code> and <code>Redirect</code> directives from <b><?=$evaluationNamePrevious?></b>.</li>
<li>Paste the <code>Alias</code> and <code>Redirect</code> directives from <b><?=$evaluationNamePrevious?></b> below the <comm class=""># <?=$evaluationType?> <?=$evaluationNumber?></comm> comment.</li>
</ol>
</li>
<li>Modify and test all of the <code>Alias</code> and <code>Redirect</code> directives until they work as they did in <b><?=$evaluationNamePrevious?></b>.
<br>They should work from the <b>CST1611.test</b> host. Using <b class="copyText">http://CST1611.test/<?=$evaluationNamePrevious?></b> as the starting URL.
<ol>
<li>Fix the Alias from one directory to another directory. (Lab 3 step 3)</li>
<li>Fix the Alias from one file to another file. (Lab 3 step 4)</li>
<li>Fix the Redirect from a directory to another site. (Lab 3 step 5)</li>
<li>Fix the Redirect from a file to another site. (Lab 3 step 6)</li>
<li>Fix the Redirect from a directory to another directory. (Lab 3 step 7)</li>
<li>Fix the Redirect from nothing to a directory. (Lab 3 step 8)</li>
</ol>
<note>Hint: The first parameter of any <code>Alias</code> or <code>Redirect</code> directive is relative the the <code>DocumentRoot</code> of the site. It is the URL that is in the browser location bar w/o the protocol and host name.</note>

<span class="warning bold">WARNING! Throughout this lab you should be aware of your browser's ability to load a page from cache.
You may need to force a page refresh (Ctrl-Shift-R) or even close and reopen the browser in order to see what is really happening now.</span>
<p>
<code>Alias URL-path file-path|directory-path</code> directive:
<ul>
<li>The <code>URL-path</code> parameter must be relative the the <code>DocumentRoot</code>.</li>
<li>The <code>path-to-file|path-to-directory</code> parameter must be relative to the file system.</li>
<li>Trailing slashes are important in the <code>Alias URL-path file-path|directory-path</code> directive too.</li>
<li>When <code>Alias</code>ing files neither the <code>URL-path</code> nor <code>path-to-file|path-to-directory</code> should ever end with a /.</li>
<li>When <code>Alias</code>ing directories both the <code>URL-path</code> and the <code>path-to-file|path-to-directory</code> need to be the same, either ending or not ending with a /.</li>
</ul>
</p>
<p>
<code>Redirect [status] URL-path URL-to</code> directive:
<ul>
<li>The <code>URL-path</code> parameter must be relative the the <code>DocumentRoot</code>.</li>
<li>The <code>URL-to</code> parameter must be relative the the <code>DocumentRoot</code> or a full URL to another Website.</li>
<li>When using the <code>Redirect [status] URL-path URL-to</code> directive a trailing slash (/) is important.</li>
<li>If the <code>URL-path</code> ends in a / it only works for a directory or if the <code>URL-path</code> typed into the browser location bar ends with a /.<br>
The way it works is that:
<ul>
<li>If <code>URL-path</code> ends with a / the browser location URL must also or the <code>Redirect</code> will not work.</li>
<li>If <code>URL-path</code> does not end with a / the browser location URL can end with a / or not.</li>
</ul>
</li>
<li>In order for a <code>Redirect</code> directive to work neither the <code>URL-path</code> nor the <code>URL-to</code> need actually exist.</li>
<li>Note that the <code>URL-to</code> should never end with a /.</li>
</ul>
