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 cache that new content.
- Cache Prefetch allows the origin server to proactively send the most current content to a CDN PoP. If a user requests the content, the CDN PoP immediately returns the cached content. It does not need to pull any new content.
Prerequisites
Cache purge and prefetch can only be configured for domain names in the Enabled or Configuring state. For more information about the domain status, see Viewing Basic Domain Information.
