CDN-Cache-Control: Precision Control for your CDN(s)

Introduced CDN-Cache-Control and Cloudflare-CDN-Cache-Control response headers to provide granular control over CDN caching behavior, allowing origins to specify caching directives for specific CDNs separately from other intermediaries and browsers. Detailed header precedence rules and interactions with existing Cloudflare features like Edge Cache TTL and Browser Cache TTL page rules. Provided examples of how these new headers can be used to manage caching behavior across multiple caching layers.
