Torchbox Cloudflare Worker Recipes
common-caching.js
Worker for handling common operations when using Cloudflare as a frontend cache:
- Skip cache when private cookies are present
- Strip querystring keys that don't need to hit the server
holding-page.js
Worker for putting up a holding page from an external source.
- Allows updating the markup without access to the Cloudflare dashboard
insert-banner.js
Inject some content specified within the worker in to the response using the HTMLRewriter API.
Useful in a pinch when you need to get an alert banner up.
insert-content.js
Replace comments on the source page with the content of requests to the specified URLs.
e.g. a source page containing
<html>
<body>
<!-- include https://www.torchbox.com/ -->
</body>
</html>
will include the contents of a request to www.torchbox.com.
Also works with relative paths.
