Support assets on a CDN

[laantorchaweb]

Hey @jkleinsc, any ideas on how to work when the assets are on a CDN?

Right now it throws a security error, and that's expected. I tried setting includeRegistration to false so I can start the service worker from my domain.

But, even if the service worker is installed none of the resources on the CDN are being cached.

You need to specify the origin of the assets, for example

cacheFirstURLS: [{
  route: '/(.*)'
  options: {
    origin: 'https://yourcdn.com/'
  }
}]

Would use the cache first strategy on all items sitting on https://yourcdn.com/

More details about this can be found in the readme here: https://github.com/jkleinsc/broccoli-serviceworker#routing-options

Thanks!, this does save the assets on the cache storage with the URLs pointing correctly to the CDN. But it doesn't fetch the assets from there on the request. My vendor and app javascript files are also on the CDN, but I don't see that could be a problem.

service-worker and sw-toolbox are local files not on the CDN. I'll keep looking into it. Thanks.
