PHP proxy that injects wildcard CORS headers into the HTTP response.
Caution
This script is unthrottled and makes no security checks, do not run it on a public server!
Install index.php
at path /uncors in your web server, then use proxy URL:
https://your.hostname/uncors/?url=URL
to retrieve URL with CORS-enabled headers.
