# WSGI 포함하기 - Flask, Django 그 외

[서브 응용 프로그램 - 마운트](sub-applications.md){.internal-link target=_blank}, [프록시 뒤편에서](behind-a-proxy.md){.internal-link target=_blank}에서 보았듯이 WSGI 응용 프로그램들을 다음과 같이 마운트 할 수 있습니다.

`WSGIMiddleware`를 사용하여 WSGI 응용 프로그램(예: Flask, Django 등)을 감쌀 수 있습니다.

## `WSGIMiddleware` 사용하기

`WSGIMiddleware`를 불러와야 합니다.

그런 다음, WSGI(예: Flask) 응용 프로그램을 미들웨어로 포장합니다.

그 후, 해당 경로에 마운트합니다.
