         <p>If your server is configured to serve each different file with the correct caching headers, serving mutable content with a <code>Cache-Control: no-cache</code> header, and immutable content with <code>Cache-Control: max-age=31536000</code>, then you might not need <code>cache.adderall(</code>⚡<code>)</code> at all.
