How to I know that my site's static files are really served by cloudflare servers?

GTMetrix telling me that I’m not using and CDN, while I host on Cloudflare.
Checking the files headers, I do not see any CF headers like CF-Cache-Status.
Any idea how can I make sure that my static file really served by Cloudflare?

Is your site set up and proxyed correctly? I’m getting the header server with Litespeed. It should show Cloudflare.

HTTP/2 200 OK

You need to switch from :grey: to :orange: to enable the Cloudflare CDN and any other features that require the proxy to function.
