Duration in milliseconds after which a request to the client is triggered. In case of TIMER components this is the actual polling duration (every xxx milliseconds), in case of LONGPOLLING components this is the duration after which the new polling request is sent to the server (in order to avoid, that there are too many requests).
| 0 | Deactivated |
| 1000 | 1000 milliseconds |
| 2000 | 2000 milliseconds |
Binding to a server side object implementing the IPageBean interface.

| URL | Polling by URL-connection |
| WEBSOCKET | Polling by WebSocket connection |
