## Technische Details { #technical-details }

FastAPI implementiert einige bewährte SSE-Praktiken direkt out of the box.

- Alle 15 Sekunden, wenn keine Nachricht gesendet wurde, einen **„keep alive“-`ping`-Kommentar** senden, um zu verhindern, dass einige Proxys die Verbindung schließen, wie in der [HTML-Spezifikation: Server-Sent Events](https://html.spec.whatwg.org/multipage/server-sent-events.html#authoring-notes) vorgeschlagen.

## Detalhes Técnicos { #technical-details }

O FastAPI implementa algumas boas práticas de SSE prontas para uso.

- Enviar um comentário de keep alive `ping` a cada 15 segundos quando não houver mensagens, para evitar que alguns proxies fechem a conexão, como sugerido na [especificação HTML: Server-Sent Events](https://html.spec.whatwg.org/multipage/server-sent-events.html#authoring-notes).

passing a pointer to a field in a struct, the Go memory in question is
the memory occupied by the field, not the entire struct. When passing a
pointer to an element in an array or slice, the Go memory in question is
the entire array or the entire backing array of the slice.

C code may keep a copy of a Go pointer only as long as the memory it
points to is pinned.

C code may not keep a copy of a Go pointer after the call returns,
