+    <h2 class="clearfix">Path Fudging</h2>
+    <p>
+      The server for GitLab Pages does some path fudging to make user experience
+      better, but you have to make sure you account for that fudging when you
+      purge the cache by URLs. The fudging rules are:
+    </p>
+    <ul>
+      <li>Directories can be accessed with or without a trailing slash.</li>
+      <li>Files can be accessed with or without a trailing slash.</li>
+      <li>
+        Files with the <code>.html</code> extension can be accessed with or
+        without the file extension.
+      </li>
+    </ul>
+    <p>
+      So every HTML file has four URLs it can be accessed on, and every other
+      file and directory has two. Here are some examples:
+    </p>
+    <ul>
+      <li><a href="cache-test.html">cache-test.html</a>
+      <li><a href="cache-test">cache-test</a>
+      <li><a href="cache-test.html/">cache-test.html/</a>
+      <li><a href="cache-test/">cache-test/</a>
+      <li><a href="style.css">style.css</a>
+      <li><a href="style.css/">style.css/</a>
+      <li><a href="sub">sub</a>
+      <li><a href="sub/">sub/</a>
+    </ul>
