[TF-AP] FYI - HTTP Web Push protocol

The IETF webpush WG seems relevant to the binding of the web of things data model to HTTP, and is analogous to the CoAP OBSERVE mechanism.  In essence, a client subscribes to events that are then pushed to it via HTTP 2 server push. I haven’t looked at the details, but suspect this includes provision for keep alive messages to ensure that a Firewall/NAT doesn’t block the server push messages.

Webpush WG: https://datatracker.ietf.org/wg/webpush/documents/

One of the recent drafts is: "Generic Event Delivery Using HTTP Push”
