What Are the Differences Between Cache Purge and Cache Prefetch?

  • Cache purge

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