### Contenedores con Múltiples Procesos y Casos Especiales { #containers-with-multiple-processes-and-special-cases }

Por supuesto, hay **casos especiales** donde podrías querer tener **un contenedor** con varios **worker processes de Uvicorn** dentro.

Pero cuando importas `Query`, `Path`, `Depends`, `Security` y otros de `fastapi`, en realidad son funciones que devuelven clases especiales.

///

## Usar `SecurityScopes` { #use-securityscopes }

Ahora actualiza la dependencia `get_current_user`.

Esta es la que usan las dependencias anteriores.

    Server->>Proxy: HTTP Response<br/>con URLs HTTPS correctas

    Proxy->>Client: HTTPS Response
```

El **proxy** intercepta el request original del cliente y añade los *headers* especiales de reenvío (`X-Forwarded-*`) antes de pasar el request al **application server**.

Estos headers preservan información sobre el request original que de otro modo se perdería:

* **X-Forwarded-For**: La IP original del cliente

Mas quando você importa `Query`, `Path`, `Depends`, `Security` entre outros de `fastapi`, eles são na verdade funções que retornam classes especiais.

///

## Utilize `SecurityScopes` { #use-securityscopes }

Agora atualize a dependência `get_current_user`.

Este é o usado pelas dependências acima.

MinIO does not assume or require that the client-provided key is unique. It may be used for multiple objects or buckets. Especially a single client-provided key may be used for all objects - even though all objects must be treated as compromised if that key is ever compromised.

#### Key rotation

       has extensive [user documentation](./docs), and it is not the role
       of Javadoc to replace that.
        * If a method's performance is "unexpected" then it's good to call that
           out in the Javadoc. This is especially helpful if the method is usually fast but sometimes
           very slow (shakes fist at caching).

                            NOTE: Users occasionally misuse the id "local" for remote repos which screws up the metadata
                            of the local repository. This is especially troublesome during snapshot resolution so we try
                            to handle that gracefully.

`OAuth2PasswordRequestForm` no es una clase especial para **FastAPI** como lo es `OAuth2PasswordBearer`.

`OAuth2PasswordBearer` hace que **FastAPI** sepa que es un esquema de seguridad. Así que se añade de esa manera a OpenAPI.
