+    <p>This page allows testing various HTTP statuses and network errors.</p>
+    <p>To test an HTTP status, simply pass it as a query param: <code>/network-error/http_status/?code=404</code></p>
+    <p>Examples below:</p>
+
+    <ul>
+        <li>
+            <a href="http_status/?code=401">401 Unauthorized</a>
+            - will also set the <code>WWW-Authenticate Response</code> header
+        </li>
+        <li><a href="http_status/?code=404">404 Not Found</a></li>
+        <li><a href="http_status/?code=500">500 Internal Server Error</a></li>
