Cache API: Manual Control Over Network Responses
The Cache API is a key-value store for network requests you control directly, unlike the browser's automatic HTTP cache. Use it in service workers for offline support or to pre-cache app assets.
The Cache API is a persistent, script-controlled key-value store where keys are `Request` objects and values are `Response` objects, separate from the browser's automatic HTTP cache. It's essential for service workers in PWAs, enabling offline support by letting you intercept requests and serve cached responses. You can also pre-cache critical assets for instant loading. The main footgun: it completely ignores HTTP caching headers. You are responsible for all updates, versioning, and deleting stale entries.
