Hi Ray
The protocol is one of those things that "just happened - just
worked" and is not well documented.
There are 2 primary calls that the client makes to the central server.
"/auth/" (authorizes a new login, overloaded to also mean re-check
existing connection, also update per-connection statistics)
"/ping/" (sends heartbeat to auth server to indicate it's still
alive. Carries extra info such as system load/uptime/freemem etc.)
The client stops re-directing web browsers to the central server once
that web browser has successfully authenticated. This causes a
firewall rule to be inserted in iptables that lets the user's port 80
traffic get router properly instead of being re-directed to wifidog's
internal web server (and therefore a second-redirect to the wifidog
central server)
A high-level overview of the protocol's logic is here:
