Index age 34 sThe full published index. Facets are resolved against a cached index document, so filtering never touches the origin — only opening an asset issues a signed URL.
How this index is served
The index is a derived document, not a database query per visitor. It is rebuilt when an asset is published and served from the edge, which is why this page stays fast while a thousand people stream the same training video.
| Object | Endpoint | Cache policy |
|---|---|---|
| Index document | media.nbcdn.example | public, s-maxage=60, stale-while-revalidate=300 |
| Grid thumbnails | media.nbcdn.example | public, max-age=604800, immutable |
| Personal facets | portal.northbay.example | private, no-store |
| Signed URL issue | portal.northbay.example | no-store · per request |
Entitlement is enforced when the signed URL is issued, never by hiding rows in a cached index. Assets you cannot open are absent from the index build for your role group.

Manifests contain paths and checksums only. The download manager requests its own signed URLs, one per file, so a manifest can be shared without granting access.
