## Pasos

Entonces, digamos que tienes un frontend corriendo en tu navegador en `http://localhost:8080`, y su JavaScript está tratando de comunicarse con un backend corriendo en `http://localhost` (porque no especificamos un puerto, el navegador asumirá el puerto por defecto `80`).

    // This may be mutated by releaseConnectionNoEvents()!
    val candidate = connectionUser.candidateConnection() ?: return null

    // Make sure this connection is healthy & eligible for new exchanges. If it's no longer needed
    // then we're on the hook to close it.
    val healthy = candidate.isHealthy(connectionUser.doExtensiveHealthChecks())
    var noNewExchangesEvent = false
    val toClose: Socket? =
      candidate.withLock {

        // Act
        int responseCode = ntlmConnection.getResponseCode();

        assertEquals(HTTP_UNAUTHORIZED, responseCode);
        // Since we don't use NTLM, no reconnection should happen
