What cache is available on the frontend (web and mobile)?

On the frontend (web and mobile applications), different cache levels are used to speed up loading and reduce load:

1. Browser HTTP Cache — stores responses to HTTP requests (HTML, CSS, JS, images) according to Cache-Control headers, ETag, etc.
2. Service Worker Cache (Cache API) — allows the application to manage the cache independently, for example, for offline mode.
3. LocalStorage / SessionStorage — stores small amounts of data on the client side, not a cache in the traditional sense, but can be used for data caching.
4. IndexedDB — a more complex storage for large volumes of structured data, used for caching application data.
5. Mobile application cache — at the platform level (iOS, Android), applications can use their own caching mechanisms, such as SQLite, file system, or built-in HTTP client caches.

These mechanisms help reduce load times, decrease traffic, and ensure application operation in offline mode.
