Checkpoint 1.11 - Mobile-PDA

Users should have control over refreshing of pages content in order to provide context and understanding of the information displayed. Automatic refreshing of content can be very disorienting to some users, as well as possibly adding delays to receiving the required information and adding cost if a page is left open or put unnoticed into the background.

Requirement

There is no auto-refresh, unless the user is notified and can stop the refresh

Recommendation

If auto-refresh is required by the application, also inform the user that the refreshing may expose them to higher usage costs.

Checking Tool

Check the source code of the page for an occurrence of the <meta> element with http-equiv="refresh". If auto-refresh occurs, ensure there is an option to stop the refresh from taking place.
