The new [ParseCookie] function parses a Cookie header value and
returns all the cookies which were set in it. Since the same cookie
name can appear multiple times the returned Values can contain
more than one value for a given key.

The new [ParseSetCookie] function parses a Set-Cookie header value and

    API key authentication using a cookie.

    This defines the name of the cookie that should be provided in the request with
    the API key and integrates that into the OpenAPI documentation. It extracts
    the key value sent in the cookie automatically and provides it as the dependency
    result. But it doesn't define how to set that cookie.

            requestConfigBuilder.setCookieSpec(cookieSpec);

        // cookie store

}

// ErrNoCookie is returned by Request's Cookie method when a cookie is not found.
var ErrNoCookie = errors.New("http: named cookie not present")

// Cookie returns the named cookie provided in the request or
// [ErrNoCookie] if not found.
// If multiple cookies match the given name, only one cookie will
// be returned.

# Headers de Respuesta

## Usar un parámetro `Response`

Puedes declarar un parámetro de tipo `Response` en tu *función de operación de path* (de manera similar como se hace con las cookies).

Y entonces, podrás configurar las cookies en ese objeto de response *temporal*.
