push-register (pushregistrationlost / pushsubscriptionchange) behavior when clearing browser cache about push-api HOT 6 CLOSED

If clearing the cache clears Service Workers, then there wouldn't be anywhere to deliver the event to anyway.

Any identifiers that are generated by the API need to be cleared when cookies are cleared. Clearing cookies is usually a trigger for removing tracking mechanisms, and registration identifiers are definitely tracking mechanisms.

We have this covered in the Security and privacy considerations section.

When a service worker registration is unregistered, any associated push subscription must be deactivated.

Clearing data deletes the Service Worker registration, which deactivates the push subscription, which (eventually) tells the push service, that then can tell the application server.

How exactly does the push service tell the application server that the subscription has been deactivated?

@delapuente The app server will get a 404 or a 410 when it tries to send to the subscription.
