Very simple HTTP proxy built for Cloudflare Workers.
The proxy will look for a URL in the ophost query parameter. A simple URL generator for this is given when missing an ophost.
If no host is found from the ophost query parameter it will fallback to searching the referer header for one, if it finally fails to find one here it will attempt to use the ophost from the cookie. This will only be set if the user has already navigated to a page using the ophost parameter before.
This will proxy most traffic through it, allowing you to easily block content from ever reaching the browser.
Example: https://[proxy-url]/0aoq/cf-worker-proxy/?ophost=github.com
