이 섹션에서는 다른 미들웨어들을 사용하는 방법을 알아보겠습니다.

## ASGI 미들웨어 추가하기

**FastAPI**는 Starlette을 기반으로 하고 있으며, <abbr title="Asynchronous Server Gateway Interface">ASGI</abbr> 사양을 구현하므로 ASGI 미들웨어를 사용할 수 있습니다.

미들웨어가 FastAPI나 Starlette용으로 만들어지지 않아도 ASGI 사양을 준수하는 한 동작할 수 있습니다.

일반적으로 ASGI 미들웨어는 첫 번째 인수로 ASGI 앱을 받는 클래스들입니다.

## ASGI Servers { #asgi-servers }

Let's go a little deeper into the details.

FastAPI uses a standard for building Python web frameworks and servers called <abbr title="Asynchronous Server Gateway Interface">ASGI</abbr>. FastAPI is an ASGI web framework.

## Servidores ASGI

Vamos a profundizar un poquito en los detalles.

FastAPI usa un estándar para construir frameworks de web y servidores de Python llamado <abbr title="Asynchronous Server Gateway Interface">ASGI</abbr>. FastAPI es un framework web ASGI.
