FAQ

• Subscribers are getting 403 with push_stream_authorized_channels_only set to on. Why?

When push_stream_authorized_channels_only is set to on the subscriber can connect only on existing channels.
But, to allow channels be collected, when no new message is published to it, channels without stored messages are considered as nonexistent for subscriber point of view.
In summary, when using this feature, the subscriber will only connect on channels with messages.

• What's a broadcast channel? What it's for?

A broadcast channel is a regular channel with a specific name prefix, except when the push_stream_authorized_channels_only is set to on.
In the case authorized_only is on, the subscriber is not allowed to create a channel, except if the channel is a broadcast channel. But, the subscriber cannot create a broadcast channel without connect to an existent channel on the same connection.
