A network system includes a first server that can receive a first message from a client application running on one of the plurality of computer devices in a non-persistent network connection. The first message includes client status information about the client application. The first server can produce a data base query in response to the first message. A data base can store the client status information about the client application in the first message. The first server can produce a second message in response to results of the data base query. The first server can send the second message to the client application in the non-persistent network connection. A second server can receive a third message from the client application in a persistent network connection and respond to the client application in real time without requiring a data query at a data base.
