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. Use Page Rules to implement custom caching options.

The "CF-Cache-Status: DYNAMIC" response header seems to indicate that the file was not cached.

That's correct. The only cached resources on this page are the gifs, jpgs, pngs and favicon.
The html page and the hit counter (counter.pl) aren't cached.
