This feature allows Cloudflare to ensure that we have cached objects ready for your users when they make a request. Prefetch serves them at once, versus making separate requests for each object.
But the document didn’t tell about the interval in which the contents will be fetched from origin.
For example, If I have cache TTL as 3 hours, after 3 hours my contents are being fetched from Origin. Does Prefetching helps here? If yes, does it automatically fetch the contents from Origin after its expiry?
