What Are the Differences Between Cache Purge and Cache Prefetch?

Cache purge
After you submit a cache purge request, cached content on CDN PoPs will be forcibly expired. If a user requests that content, CDN has to pull fresh content from the origin server and then caches that new content.

Cache prefetch
After you submit a cache prefetch request, the origin server proactively sends the most current content to a CDN PoP for caching. If a user requests the content, the CDN PoP immediately returns the cached content. It does not pull any new content.
