## Agregando middlewares ASGI

Como **FastAPI** está basado en Starlette e implementa la especificación <abbr title="Asynchronous Server Gateway Interface">ASGI</abbr>, puedes usar cualquier middleware ASGI.

Un middleware no tiene que estar hecho para FastAPI o Starlette para funcionar, siempre que siga la especificación ASGI.

    strategy:
      # When ldap, etcd or openid vars are empty below, those external servers
      # are turned off - i.e. if ldap="", then ldap server is not enabled for
      # the tests.
