Introducing Cache Response Rules
Cloudflare Blog 2026-07-23 18:40:38
Context: Cloudflare has introduced a new feature called Cache Response Rules, designed to address issues with caching content that should be exempted due to specific headers. This feature aims to provide a solution for cases where headers such as Set-Cookie or Cache-Control, which are difficult to modify at the origin, cause cached content to be unnecessarily re-fetched from the origin server.
Key Facts
- Cache Response Rules is a new feature introduced by Cloudflare to modify cache behavior based on specific response headers, allowing for more precise control over caching content.
- The feature targets issues caused by headers like Set-Cookie or Cache-Control that are difficult to change at the origin server, which previously could cause cached content to be dragged back to the origin unnecessarily.
- By applying Cache Response Rules, users can ensure that content is properly cached or excluded based on specific conditions, without having to alter the origin server's configuration.
