How Do I Synchronize Content Cached on CDN PoPs with That on the Origin Server?

  • You can set cache rules. For content that is frequently updated, you can set a cache rule with a short cache TTL. For other content, you can set a cache rule with a long cache TTL to reduce the pressure on the origin server.
  • If the configured cache TTL is not reached but new content is released or content is deleted on the origin server, you can manually purge the cache.
    • Log in to the console and choose Service List > Content Delivery & Edge Computing > Content Delivery Network. In the navigation pane, choose Prefetch & Purge. On the Purge tab, refresh the cache.
