Service Worker Cache and Offline Storage Information

Use this page to inspect the service worker's current cache snapshot, including cached pages, stored assets, entry age hints, and the browser's storage estimate.

If you are checking offline behavior, the panel below is a friendlier option than rummaging through browser storage by hand. It reflects what this browser has cached right now, so the result can change after a visit, refresh, deployment, or cleanup.

What appears in the panel:

• Cache groups, sorted by name, with an item count beside each heading.
• Readable paths for cached pages and assets, linked so you can open them directly.
• Short age labels such as 5m, 2d, or 3M when the cached response exposes a usable timestamp.
• A storage summary showing the browser's current usage and quota estimate.

Why the list changes:

This page shows a live snapshot rather than a fixed checklist. If a page or asset has not been visited recently, it may not appear yet. Cache names can also shift after a deployment, and older entries may disappear when the browser clears data.

You may also see separate groups for resources fetched from approved external hosts. That is expected. The service worker keeps them apart so it can manage those files without mixing them into the main site caches.
