### Lanza un `HTTPException` en tu código

`HTTPException` es una excepción de Python normal con datos adicionales relevantes para APIs.

Debido a que es una excepción de Python, no la `return`, sino que la `raise`.

Hablaremos del `@lru_cache` en un momento.

Por ahora puedes asumir que `get_settings()` es una función normal.

Y luego podemos requerirlo desde la *path operation function* como una dependencia y usarlo donde lo necesitemos.

It will be called by **FastAPI** whenever it receives a request to the URL "`/`" using a `GET` operation.

In this case, it is an `async` function.

---

You could also define it as a normal function instead of `async def`:

/// note

                    }
                    return loc;
                }

                // fallthrough to normal handling
                log.debug("No tree referral but in DFS");
            }

            if (request != null) {
                request.setFullUNCPath(session.getTargetDomain(), session.getTargetHost(), rfullpath);
            }

Será llamada por **FastAPI** cuando reciba un request en la URL "`/`" usando una operación `GET`.

En este caso, es una función `async`.

También podrías definirla como una función normal en lugar de `async def`:

/// note | Nota

There could be cases where you need to do some **custom validation** that can't be done with the parameters shown above.

In those cases, you can use a **custom validator function** that is applied after the normal validation (e.g. after validating that the value is a `str`).
