    provided.
 *  Fix: Enforce that callers call `WebSocket.close()` on IO errors. Error
    handling in WebSockets is significantly improved.
 *  Fix: Don't use SPDY/3 style header concatenation for HTTP/2 request headers.
    This could have corrupted requests where multiple headers had the same name,
    as in cookies.

Una alternativa que podrías usar para capturar excepciones (y posiblemente también lanzar otra `HTTPException`) es crear un [Manejador de Excepciones Personalizado](../handling-errors.md#install-custom-exception-handlers){.internal-link target=_blank}.
