FastAPI implements some SSE best practices out of the box.

* Send a **"keep alive" `ping` comment** every 15 seconds when there hasn't been any message, to prevent some proxies from closing the connection, as suggested in the [HTML specification: Server-Sent Events](https://html.spec.whatwg.org/multipage/server-sent-events.html#authoring-notes).

# Seconds between keep-alive pings when a generator is idle.
# Private but importable so tests can monkeypatch it.
