Routing SPA hosted in buckets

When hosting static files in buckets like S3, you might want to use the browser's history API for routing without relying on a server-side framework. This is especially useful for single-page applications (SPAs) or when you want to handle routing on the client side.

It's possible to upload a single index.html file to the bucket but it only get's served when the path is / or /index.html.

To get the browser to load the same html file for all paths, its possible to use a 404.html file in the bucket instead of index.html.
