The outputConnectionStatus component displays the information about the status of the network connection between the client browser and the server. The component displays one of 4 possible states, which are as follows.
1. Active: The connection is alive and there is a request pending.
2. Inactive: The connection is alive and there is no pending activity.
3. Caution: The connection request/response latency has exceeded the configured threshold. Indicates that asynchronous updates from the server may not be received in a timely manner.
4. Disconnected: The connection has been lost, either due to network or application error (session expiry, etc.).
The outputConnectionStatus component provides an ideal mechanism to provide continuous real-time feedback to users of the status of their ICEfaces application. It is particularly important to inform users when the application is busy sending and receiving data in response to a user-initiated action to manage their expectations with respect to application readiness for additional user input. Generally, the outputConnectionStatus component should be located in a consistent location throughout an ICEfaces application.
NOTE: A web-page may only contain a single outputConnectionStatus component. Using more than one outputConnectionStatus component on the same web page will result in erratic results.
