"CF-Cache-Status" is found in the response header when a resource is cached on Cloudflare's CDN.
This tool uses PHP's get_headers function to fetch the header information for a resource, looks for the CF-Cache-Status in the response, and then reports on what is found. Enter any URL above to test.
Note: Redirects will not be followed.
Note: Cloudflare's static content caching is dependent on both (a) where most of your visitors are coming from and which Cloudflare datacenter they are hitting, and (b) how may times those resources are requested at the specific datacenter. As such, Cloudflare does not cache the same resources for your site globally at every datacenter location.
If the "CF-Cache-Status" header is missing (but you are seeing other Cloudflare headers such as "CF-RAY"), this can indicate that the resource is not something Cloudflare would ordinarily cache. There is a list of file extensions Cloudflare caches by default and you can utilize Page Rules to implement custom caching options (including static content and HTML).
