Cache
The new styles are deployed, but some people still see the old version. Find out which cache layer has not updated.
GET /app.css200 app.css200 · transferred 18 kBA hit reuses a stored copy: When a browser or shared cache finds a reusable response, it can return the resource without contacting the origin, reducing wait and transfer. A request result does not always come from the origin.
An old copy can be revalidated: When a copy is stale, a cache may ask the origin whether it changed. An unchanged resource can produce 304; a changed one returns new content. Diagnose updates with hit, revalidation, and invalidation evidence.
You can say this to an AI Agent
Find out whether this old CSS comes from the browser cache, a CDN/shared cache, or the origin. Check the resource URL, response headers, and requests from different locations. Then invalidate the old copy or update the resource address as appropriate, and verify both local and external requests. Do not treat Browser Storage as the cache diagnosis.
