The Cloudflare Image Resizing service is billed by the number of resizing requests. Free for under 50,000 requests, and $9 per 50,000 if that’s over.
I have a site with less than 1000 images. From my understanding, there shouldn’t be any resizing requests after all these images are resized and cached for the first time. However, I noticed in the billing usage that every day there are resizing requests, and some days may even have more than 4k+ requests. So I wonder:
- How exactly are resizing requests calculated?
- How frequent is the resized image cache refreshed? Do we have any visibility or control on that via Cloudflare dashboard?
