I'm using Azure CDN for Azure Blob image uploads but it doesn't seem to be correctly caching images on my website.
I've set the Blob Cache-Control: max-age=4233600 and it seems to work when I directly call from the blob URL. However, calling from the CDN URL shows max-age=0. I'm not sure if I've missed something, but I can't see any way to edit the CDN's Cache-Control. Where am I going wrong?
