🐞 [BUG]: browsers run code from a older deployment

[andreaskundig]

Is there an existing issue for this?

Current Behavior

This happens after new deployments.

One time the sqlite wasm file was missing in the deployment, but the application continued working in a browser that still had the file in the application cache. This is not the same as the browser cache, and is not purged when you clear the browser cache.

The last time it happened was at the introduction of UnitKepler that generates the content of its iframe instead of taking it from a file on the server. In PO's browser, the uber map for rider points showed "This page not found", which looks like it was looking for the file that was removed.

Expected Behavior

Always use the latest version of the application.

I think we need to actively bust the application cache when a new version of the application is deployed. I found this blog post that seemed relevant, but haven't read it yet.

Steps to Reproduce

It's a bit hard to reproduce, but you could add some code that loads a file on a test page, deploy it, and see that it loads the file. Then remove the file and redeploy it. Then you would expect that test page to fail loading the removed file, but it would probably be loaded from the application cache instead.
