-/* SESSION LIMITING
- *
- * The basic idea of session limiting is to prevent one host from having more
- * than a specified number of sessions (client connections/clones) on the
- * network at any one time. To do this we have a list of sessions and
- * exceptions. Each session structure records information about a single host,
- * including how many clients (sessions) that host has on the network. When a
- * host reaches it's session limit, no more clients from that host will be
- * allowed to connect.
- *
- * When a client connects to the network, we check to see if their host has
- * reached the default session limit per host, and thus whether it is allowed
- * any more. If it has reached the limit, we kill the connecting client; all
- * the other clients are left alone. Otherwise we simply increment the counter
- * within the session structure. When a client disconnects, we decrement the
- * counter. When the counter reaches 0, we free the session.
- *
- * Exceptions allow one to specify custom session limits for a specific host
- * or a range thereof. The first exception that the host matches is the one
- * used.
