Return Proxy

Cloudflare Worker for returning branded error pages when an upstream request fails.

Deploy

From this folder:

npx wrangler deploy

That is the normal deploy flow for this project.

The worker checks the upstream once and returns a safe fallback page on failure.
It handles common statuses like 404, 502, 503, and 504.
The main config is in wrangler.toml and the worker code is in src/worker.js.
