Todo lo que necesitamos hacer es manejar el request dentro de un bloque `try`/`except`:

{* ../../docs_src/custom_request_and_route/tutorial002.py hl[13,15] *}

Si ocurre una excepción, la `Request instance` aún estará en el alcance, así que podemos leer y hacer uso del request body cuando manejamos el error:

{* ../../docs_src/custom_request_and_route/tutorial002.py hl[16:18] *}

## Clase personalizada `APIRoute` en un router

	// Since `apiRouter` satisfies `http.Handler` it has a ServeHTTP to execute the logic of the handler.
	// Call the ServeHTTP to execute the handler.
	apiRouter.ServeHTTP(rec, req)

	ctx, cancel := context.WithCancel(GlobalContext)
	defer cancel()

	// Now check if we actually wrote to backend (regardless of the response
	// returned by the server).
	z := obj.(*erasureServerPools)
	xl := z.serverPools[0].sets[0]

   * call this without consuming the complete response body, any remaining bytes in the response
   * body will be discarded before trailers are returned.
   *
   * If [Call.cancel] is called while this is blocking, this call will immediately throw.
   *
   * @throws IllegalStateException if the response is closed.

 *  New: Upgrade to Okio 2.4.3.

    ```kotlin
    implementation("com.squareup.okio:okio:2.4.3")
    ```

 *  Fix: Limit retry attempts for HTTP/2 `REFUSED_STREAM` and `CANCEL` failures.
 *  Fix: Retry automatically when incorrectly sharing a connection among multiple hostnames. OkHttp
    shares connections when hosts share both IP addresses and certificates, such as `squareup.com`

    idle and active connections for everything. OkHttp now detects and warns on
    connections that were allocated but never released, and will enforce HTTP/2
    stream limits. This update also fixes `Call.cancel()` to not do I/O on the
    calling thread.
 *  Fix: Don't log gzipped data in the logging interceptor.
 *  Fix: Don't resolve DNS addresses when connecting through a SOCKS proxy.
