Fetching objects from backblaze for Bandwidth Alliance

[user14995]

So our website does not have a direct DNS record of backbaze’s endpoint, then how can we still manage to download the Backbaze’s objects via Cloudflare to save Egress fees?
Thank you

Try temporarly turning of / removing, both of the Page Rules. Does anything change? Furthermore, test from my side: https://f003.backblazeb2.com/file/fritexpub/test_file.txt → wor…

Bandwidth Alliance with Backblaze free egrees for images and other files?

It doesn’t matter the file type, as long as it goes through Cloudflare. A Worker is great, lots of people use a Worker + B2 for their CDNs (me included!). We store lots of images in B2

I have been through the docs, but not what I am looking for.
Lets say, when I hit the download button on my website, the site just downloads it directly because of pre-signed URL, there is no DNS in between (screenshot below). Then how can I set it up?
