A method for sending a notification message using a modified form of User Datagram Protocol (UDP) multicast notification system in a client-server architecture that otherwise allows only client initiated messages. The method includes: identifying information at a server that has potential for inclusion in a notification message; querying a database for a list of clients that have registered for a particular type of notification by a UDP broadcast processor; receiving a reply with a list of clients that have registered for a particular type of notification from the database; and sending notification to all clients on the list using an assigned port number from the UDP broadcast processor.
