How do I debug caching issues when using Cloudflare Workers?

Cloudflare provides several debugging tools. Use `console.log()` within your Worker to log request and response headers, cache keys, and other relevant information. Cloudflare's dashboard also offers caching insights and analytics. The `Cache-Control` header is crucial; ensure it's being set correctly. You can also use the `cf-cache-status` header to check if a request hit the cache.
