Client pull (AJAX) settings
To configure the auto-disconnect and auto-refresh
functions, use the following settings:
- Polling interval (seconds)
- The interval in seconds at which the browser will poll the ZIETrans application to restart the disconnect timer,
if enabled, and check for host screen updates. The value is specified in seconds to one decimal place. The minimum
value is 1.0 second. The default is 5.0 seconds. If Disconnect is
selected, then the polling interval value must be less than the value
in the Time to wait for disconnect (seconds) setting
by at least 1 second.
Note: If an HTTP session idle timeout is configured by selecting the Set timeout option in the WebSphere® Application Server Session management settings for the application server, browser polling of the ZIETrans application effectively disables the HTTP session idle timeout functionality. Because of this, the ZIETrans runtime takes responsibility for monitoring the HTTP session idle timeout period and initiates a disconnect of the ZIETrans session, including running the disconnect event, when no user activity is seen before the idle time is exceeded.
If auto-disconnect and auto-refresh are both disabled for the current page, when an HTTP session idle timeout is triggered, ZIETrans disconnects the session and does not run the disconnect event.
- Disconnect
- Select this option to enable the auto-disconnect function.
If selected, the ZIETrans application initiates
disconnect processing if the client has not polled the ZIETrans
application within the time specified in the Time to wait for disconnect (seconds) field.
Note: Disconnect processing is performed to clean up resources associated with the browser session and thereby reduce the load on the server. To do this, the disconnect event is run, and the disconnect macro (if configured) is run
- Time to wait for disconnect (seconds)
- The time in seconds to wait before performing the auto-disconnect function. The value is specified in seconds to one decimal place. The minimum value is 2.0 seconds. The default is 15.0 seconds.
- Refresh
- Select this option to enable the auto-refresh function. If selected, the browser initiates a refresh if there has been no user input and the poll response indicates that the host screen has changed.
