### Özet

Özetlemek gerekirse, parametrelerin, gövdenin, vb. veri tiplerini fonksiyon parametreleri olarak **bir kere** tanımlıyoruz.

Bu işlemi standart modern Python tipleriyle yapıyoruz.

Using `Optional[str]` instead of just `str` will let the editor help you detect errors where you could be assuming that a value is always a `str`, when it could actually be `None` too.

`Optional[Something]` is actually a shortcut for `Union[Something, None]`, they are equivalent.

## Proxy Forwarded Headers { #proxy-forwarded-headers }

A **proxy** in front of your application would normally set some headers on the fly before sending the requests to your **server** to let the server know that the request was **forwarded** by the proxy, letting it know the original (public) URL, including the domain, that it is using HTTPS, etc.
