</do>
Example 7-2 shows how a URL helps the user navigate more easily. The Done and
Back keys take the user to the application’s home card.
■ Empty the application history when direct backward navigation is not possible.
When it is not possible to go backward (for instance, after the user confirms an
action), consider erasing the application’s history list.
Example 7-3
<do type="options" label="Done">
<go href="#clear"/>
</do>
...
<card id="clear" newcontext="true">
<onevent type="onenterforward">
<go href="home.wml"/>
</onevent>
<p>
</p>
</card>
Example 7-3 shows how to empty the history for applications requiring passwords or
secured data. This will delete variables in the handset. If this is not desirable, use an
onenterbackward to catch the backward navigation.
