Overview

CDN can purge and prefetch content.

  • Cache Purge forces cached content on CDN PoPs to expire. If a user requests that content, CDN has to pull fresh content from the origin server and then caches that new content.
  • Cache Prefetch allows the origin server to proactively send the most current content to CDN PoPs. If users request the content, CDN PoPs immediately return the cached content. They do not need to pull any new content.

Prerequisites

Cache purge and prefetch can only be performed for unbanned domain names in the Enabled or Configuring state. For more information about the domain status, see Viewing Basic Domain Information.
