Service Worker to Redirect Origin

This is a tool for your static website which could intercept all GET requests of the origin domain and redirect them to a given base-URL. Such as /index.html to https://cdn.example.com/index.html.

It's useful when your origin domain have no ICP license but you want to optimize mainland China routing.
