Fanout

Fanout is meant to creat a simple pubsub server to handle sending messages and receiving messages on different channels.

Protocol:

ping - replies with current timestamp on the server info - replies with some basic info about the server subcribe <channel> unsubscribe <channel> announce <channel> <message>

Each request sent to the server must end with a \n. This means neither <channel> nor <message> can contain a \n itself directly (of course all of them can be encoded ie: base64).

<channel> must not contain the '!' character or spaces. <message> can contain the '!' character

Each message announced on a channel will be sent out as:

<channel>!<message>

ending with \n to all the subscribed clients.

2 special channels are automatically created and should not be used.

all - every client connected to the service is subscribed to this channel

debug - is used to send back messages to individual clients, for example upon connection "debug!connected..." is sent to confirm connection.
