How to Properly Cache Content Hosted on Backblaze B2 with Cloudflare
How to Properly Cache Content Hosted on Backblaze B2
Summary
Because I use Cloudflare to manage my domains and Backblaze for backups, it only made sense to take advantage of their Bandwidth Alliance for creating my own CDN. This has been incredibly helpful for image hosting for this knowledge base, however, I recently noticed that caching wasn't working as it should.
The Problem
The overall problem started when I was adding a parking page for a domain I recently purchased. The background image was hosted on B2 and the image was supposed to be cached by Cloudflare. However, each time the page loaded, it would pull the image from the origin instead of the cache. I checked this on my knowledge base and found it was doing the same thing.
