<li>Go to <a href="login.php" target="_blank">login.php</a></li>
<li>Open browser DevTools → Network tab</li>
<li>Submit login form</li>

<h6>SEO URL Test:</h6>
<ol>
<li>Test URL: <a href="/hotel_managment/hotel/1/test-hotel" target="_blank">/hotel/1/test-hotel</a></li>
<li>Should redirect to view.php with id=1</li>
<li>If 404 error, check .htaccess RewriteBase setting</li>

<h6>XSS Protection Test:</h6>
<ol>
<li>Add hotel with name: <code><script>alert('XSS')</script></code></li>
