What happens in this scenario:

• you have a prod version of the app loaded in the browser
• now you make a prod deployment and file hash names have changed, potentially deleted
• Client app has obsolete or deleted references
• Then user navigates to a page which has reference to one of those un-existing file chunk
• Does the app know to reload the page or user is left with a 404 or broken page?

I am really curious to know what happens in this scenario, specially with CI/CD with multiple deployments a day.
