How this works

When given source URL(s), this page will load the source file(s) as Javascript and trigger an event similar to that in a CloudFlare Worker:

addEventListener('fetch', event => {
  event.respondWith(handleRequest(event.request))
})
  

Assuming (at least one of) the source file(s) contains a global handleRequest function, it will be called.

provide one or more source files below and submit the form.
