There are probably multiple ways to reverse proxy, it’s just that CF workers are versatile to handle many use cases. You don’t have to lose the caching benefits. You can still pull your assets through Cloudflare CDN since workers operate at the request level (afaik).

In fact it can be even more performant. You can use Workers KV to cache as well. So a request comes in, check KV store, return if found. If not, pull from asset CDN.

Don't use Workers KV for caching -- use the Cache API: https://developers.cloudflare.com/workers/reference/cache-ap...

KV is a global persistent data store, so reads and writes may have to cross the internet. In comparison, the Cache API reads and writes from the local datacenter's cache. Also, Cache API doesn't cost extra (KV does).

However, better than either of these is to formulate your outgoing fetch() calls such that they naturally get the caching properties you want. fetch() goes through Cloudflare's usual caching logic. When that does what you want, it works better because this is the path that has been most optimized over many years.

Can you point to some example code that uses fetch more optimally than Cache API?
