I've been thinking about a local proxy that caches CDN assets. The first request to a cdn URL goes through, subsequent requests come from cache. I think it would work fine with versioned libraries, fonts, etc. I'm thinking of setting up a container and squid config to achieve this. Any obvious problems or alternative solutions? Obviously enumerating the worlds CDN URLs would be a task. But I think even covering the most common CDNs would be a benefit.
