Prefetch/Purge

Prefetch and purge functions support content lifecycle management by enabling proactive caching and targeted cache invalidation.

Prefetch​

Configure prefetch to cache specific resources in advance at edge nodes.

Configuration​

  • Enter 1–25 URLs, separated by spaces.
  • Example: https://example.com/foo/bar.txt

Rate Limits​

Default domain-level rate limits:

  • 10 URLs per minute
  • 100 URLs per hour
  • 1000 URLs per day

Contact our support to adjust rate limits for specific domains.

Purge​

Configure purge to remove cached resources from edge nodes.

Configuration​

  • Enter 1–25 URLs, separated by spaces.
  • Example: https://example.com/foo/bar.txt

Important Notes​

  • Supports path-based URLs only.
  • Wildcard and regular expression matching are not supported.
  • Purge applies to individual files, not directories.
