Cloudflare Repositories FTW

What this post added

This post details how Kali Linux integrated Cloudflare's CDN for distributing large ISO images and dynamic apt repositories. Key technical contributions include: implementing custom 'Expires' HTTP headers to disable expiration for static files, using 'Cache-Tag' headers to manage metadata caching, and integrating an API call to purge metadata from the CDN cache. The post also highlights Cloudflare's development of a feature to support caching of very large files, which was crucial for Kali's image distribution.
