Origin Cache Control is a Cloudflare feature. When enabled on an Enterprise customer's website, it indicates that Cloudflare should strictly respect Cache-Control directives received from the origin server. Free, Pro and Business customers have this feature enabled by default.| Cloudflare Docs
Cloudflare respects the origin web server’s cache headers in the following order unless an Edge Cache TTL cache rule overrides the headers. Refer to the Edge TTL section for details on default TTL behavior.| Cloudflare Docs
