Notification when cache is used

[AlysioMusic]

Hi.

I have a downloading website and I use Cloudflare.

I have a downloads counter which I increment at every request.
The problem, of course, is that if I use caching, the counter does not increment at all.

Of course, I could do that clientside, but that would mean that simply accessing the address of the resource does not increment the counter.
Is there any way to have a request triggered every time the cacehd version of a certain resource is provided to the client?

You could write a worker to call your origin to increment a script or other mechanism for counting downloads.

Maybe it’s just me, but this seems like a resource that should return Cache-Control headers to prevent caching by Cloudflare as you want this resource to be accessed by the browser.
