Managing Connection Status

Managing Connection Status

Heartbeating enables an additional state for connections, so the available states are:

idle
waiting
caution
lost

The caution state occurs if heartbeats go missing, but retries are in progress. If the retries fail, the connection state will transition to lost, and if a retry succeeds the connection state will return to idle.

The outputConnectionStatus component in the ICEfaces Component Suite recognizes all four states, so applications can incorporate visual indicators for connection status. If connection lost status is determined, and no connection status component is present, ICEfaces displays a modal overlay indicating connection lost. A reload of the application is required at this point.
