SCR1: Allowing the user to extend the default time limit

Applicability

Time limits that are controlled by client-side scripting.

This technique relates to:

Description

The objective of this technique is to allow user to extend the default time limit by providing a mechanism to extend the time when scripts provide functionality that has default time limits. In order to allow the user to request a longer than default time limit, the script can provide a form (for example) allowing the user to enter a larger default time limit. Making this available as a preference setting allows users to indicate their requirements in advance. If warning the user a time limit is about to expire (see SCR16: Providing a script that warns the user a time limit is about to expire (Scripting) ), this form can be made available from the warning dialog.
