## `HTTPSRedirectMiddleware` { #httpsredirectmiddleware }

Enforces that all incoming requests must either be `https` or `wss`.

Any incoming request to `http` or `ws` will be redirected to the secure scheme instead.

## `HTTPSRedirectMiddleware`

들어오는 모든 요청이 `https` 또는 `wss`여야 합니다.

`http` 또는 `ws`로 들어오는 모든 요청은 대신 보안 체계로 리디렉션됩니다.

## `TrustedHostMiddleware`

HTTP 호스트 헤더 공격을 방지하기 위해 모든 수신 요청에 올바르게 설정된 `Host` 헤더를 갖도록 강제합니다.
