Workers Cache using fetch
Teaches how to control resource caching within Cloudflare Workers by implementing custom cache keys, setting TTLs, and overriding cache behavior based on origin response codes or file types using the fetch API.
When To Use
Use when you need to implement custom caching logic in a Worker, such as normalizing cache keys for multiple origins or adjusting TTLs and cache levels via fetch requests.

What This Skill Covers
- Determine how to cache a resource by setting TTLs, custom cache keys, and cache headers in a fetch request.
- Main sections:
Tags,Caching HTML resources,Custom cache keys,Override based on origin response code,Customize cache behavior based on request file type.
Workflow
- Open the most relevant file under
docs/for the exact documented workflow and wording. - Open
schemas/files for exact structured contracts. - Open
examples/files for concrete requests, commands, snippets, and manifests. - Do not add behavior or configuration that is not present in the attached source files.
