the benefit happens automatically, if the server response includes expiration and validation info; for example, see [HTTP caching - HTTP | MDN](https://developer.mozilla.org/en-US/docs/Web/HTTP/Caching) — using the default cache control policy, your app uses the cached version if it’s still valid.

For direct access to the cached data, see [Apple Developer Documentation](https://developer.apple.com/documentation/foundation/url_loading_system/accessing_cached_data)
