Otherwise, all subscriber requests to nonexistent channels will get a 403 Forbidden response.
 This restriction is not applied to broadcast channels, but to subscribe to a broadcast channel is necessary to subscribe at least to one normal channel, and if this directive is set to on this channel has to be created before.
