## 기술 세부사항 { #technical-details }

FastAPI는 일부 SSE 모범 사례를 기본으로 구현합니다.

- 메시지가 없을 때는 15초마다 **"keep alive" `ping` 주석**을 보내 일부 프록시가 연결을 종료하지 않도록 합니다. [HTML 사양: Server-Sent Events](https://html.spec.whatwg.org/multipage/server-sent-events.html#authoring-notes)에서 권장합니다.
- 스트림이 **캐시되지 않도록** `Cache-Control: no-cache` 헤더를 설정합니다.

А вот если открыть интерфейс документации по «официальному» URL через прокси на порту `9999`, по `/api/v1/docs`, всё работает корректно! 🎉

Проверьте по адресу [http://127.0.0.1:9999/api/v1/docs](http://127.0.0.1:9999/api/v1/docs):
