Your Worker can now have its own cache in front of it

This blog post announces and documents Cloudflare's Workers Cache: a Worker-level, tiered cache that sits in front of Worker entrypoints and is configured via Worker code and Cache-Control headers. It covers the API and configuration (wrangler.jsonc), stale-while-revalidate behavior, Vary/variant handling, multi-tenant-safe keys using ctx.props, per-entrypoint caching via exports, programmatic purges, tiered topology, observability, framework integrations (Astro), and example composition patterns for server-rendered apps.
