Why Is Data Obtained from a CDN PoP Not the Updated Data?
Cached content on CDN points of presence (PoPs) is not updated in real time. CDN PoPs only pull new content from the origin server when the previously cached content expires and then update the cache. After updating content on the origin server, you can submit cache purge requests to force the cached content on CDN PoPs to expire and ensure the latest content is updated. In this way, users can get the latest data when they access the website.
