Abstract
A method and apparatus for a client to continue to receive updates from a server when a channel has been disconnected before the expiration of a heartbeat timer is disclosed. The method includes sending a heartbeat message from the client to the server wherein the heartbeat message is sent at the expiration of a timer having a first time interval that is less than the first timeout duration period of the server. The method includes detecting that the channel is disconnected before the expiration of the first time interval and then determining a second timeout duration period from detecting the channel is disconnected.
