Is it possible to force Cloudflare to edge cache entire folder during requesting single file
images.anywebsite.com/mpSTj8xbeu/1.jpg
also force to cache:
images.anywebsite.com/mpSTj8xbeu/2.jpg
images.anywebsite.com/mpSTj8xbeu/3.jpg

Each photo on the website is downloaded with a few seconds delay due to HTML lazy-loading. So a single request to the website makes around 10 requests to:
images.anywebsite.com/mpSTj8xbeu/*.jpg
each few seconds after the previous one.
