Refresh Task
The <refresh> task refreshes some specified card variables. If any of the variables are shown on the screen, this task also refreshes the screen.
The example below uses an <anchor> tag to add a "Refresh this page" link to the card. When the user clicks on the link, he or she refreshes the page and the value of the variable x will be set to 30:
<?xml version="1.0"?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN"
"http://www.wapforum.org/DTD/wml_1.1.xml">
<wml>
<card>
<p>
<anchor>
Refresh this page
<go href="thispage.wml"/>
<refresh>
<setvar name="x" value="30"/>
</refresh>
</anchor>
</p>
</card>
</wml>
