<h2 id="bypass-case-sensitive">Bypass Case Sensitive</h2>
<p>To bypass a case-sensitive XSS filter, you can try mixing uppercase and lowercase letters within the tags or function names.</p>

<p>Since many XSS filters only recognize exact lowercase or uppercase patterns, this can sometimes evade detection by tricking simple case-sensitive filters.</p>
