Will the Cache on CDN PoPs Be Updated in Real Time?
Cached content on CDN points of presence (PoPs) is not updated in real time. CDN PoPs only obtain new content from the origin server when the previously cached content expires. If you want to update content cached on CDN PoPs, configure cache rules or submit cache purge or prefetch tasks. For details, see Cache Rules.
