Subresource Bundle Demo

This page loads its subresources with a single web bundle on supporting browsers and otherwise smoothly falls back to sending separate network requests for each resource. In the first case the background will be pink, otherwise it will be blue—this is just for the demo, since normally you'd want identical resources in the two cases.

This page was loaded without javascript.

The bundle, subresources.wbn, was created from contents.har with the command gen-bundle -har contents.har -o subresources.wbn. I needed to add application/webbundle wbn; to nginx's mime.types to get it to serve with the correct MIME type.
