Feature request - cache expiration

[jchapelle]

Would it be possible to implement cache expiration time like described in
https://phyks.me/2019/01/manage-expiration-of-cached-assets-with-service-worker-caching.html

Would it be possible to implement cache expiration via api call ?
This would be very usefull if you want to control clients cache remotely. Indeed, cache is very cool
when everything works fine. But when you cache a buggy app, you are in trouble for 24 hours ... This feature could be an emergency feature that would allow to wipeout client caches when the server tells you do it (in case of deployment of a buggy app).
