All Resources Are Preheated, and the Cache TTL Is One Year. Why Is the Requested Content Still Being Pulled from the Origin Server?

CDN PoPs regularly evict cached content that has not recently been accessed, regardless of the content's expiration time. When a user requests the evicted content, CDN has to pull it from the origin server.

You can prefetch resources again so that users can obtain the most recent resources from CDN PoPs upon first access. For details, see Cache Purge and Prefetch.
