- [HTML spesifikasyonu: Server-Sent Events](https://html.spec.whatwg.org/multipage/server-sent-events.html#authoring-notes) önerisine uygun olarak, bazı proxy'lerin bağlantıyı kapatmasını önlemek için, 15 saniye boyunca hiç mesaj gelmezse **"keep alive" `ping` yorumu** gönderir.
- Akışın **cache'lenmesini önlemek** için `Cache-Control: no-cache` header'ını ayarlar.
- Nginx gibi bazı proxy'lerde **buffering'i önlemek** için özel `X-Accel-Buffering: no` header'ını ayarlar.

        -  If you believe it should definitely be a public Keras API, please open a feature request in keras GitHub repo.
        -  As a workaround, you could import the same private symbol keras `keras.src`, but keep in mind the `src` namespace is not stable and those APIs may change or be removed in the future.
