Cannot bypass Dynamic status cache for my APIs in Cloudflare

After defining the following configuration to avoid dynamic caching for an API : Cloudflare for your API

My calls are still in a Dynamic cache status. You can see the received reponse headers :

access-control-allow-methods: GET,OPTIONS
alt-svc: h3=":443"; ma=86400, h3-29=":443"; ma=86400, h3-28=":443"; ma=86400, h3-27=":443"; ma=86400
cache-control: no-cache, no-store, max-age=0, must-revalidate
cf-cache-status: DYNAMIC

Here's the configuration i've done

Do you find a way to get a 'BYPASS' cache Clouflare Status Headers

Solution

  • If your goal is to avoid having your API calls cached, then the above page rule looks correct. You are using a Cache Level directive to Bypass the caching logic.

    This means that all the calls matching the URL pattern will always be pulled from your origin server. This is confirmed by the cf-cache-status response header valued with DYNAMIC

    From the documentation

    DYNAMIC: Cloudflare does not consider the asset eligible to cache and your Cloudflare settings do not explicitly instruct Cloudflare to cache the asset. Instead, the asset was requested from the origin web server.

    The response header cf-cache-status can also have a value of BYPASS, but this happens in other scenarios (also described in the documentation)
