After a deploy, some users keep seeing the old version of the SPA or get a blank white screen. How would you configure caching so this doesn't happen?

How to approach it

They're checking whether you understand how HTTP caching works for an SPA: what to cache for a long time, what to revalidate, and why a white screen can appear after a deploy because of deleted chunks. This isn't a question about "how to clear the cache" but about a strategy where you don't need to clear anything.
