Como você viu em [Sub Applications - Mounts](sub-applications.md){.internal-link target=_blank} e [Behind a Proxy](behind-a-proxy.md){.internal-link target=_blank}, você pode **"montar"** aplicações WSGI.

Para isso, você pode utilizar o `WSGIMiddleware` para encapsular a sua aplicação WSGI, como por exemplo Flask, Django, etc.

## Usando o `WSGIMiddleware`

Você precisa importar o `WSGIMiddleware`.
