Example 13-2
<head>
<link href="page2.wml" rel="next"/>
</head>
<card id="page1">
<do type="accept" label="More">
<go href="page2.wml"/>
</do>
<p>
Page 1 of 2<br/>
...
</p>
</card>
Example 13-2 shows how to prefetch the content of the next card. When the user
loads the deck,
page2.wml is automatically loaded in the background as soon as the
current deck is completed loading. This ensures that
page2.wml is already in the
cache when the user presses the
<do type="accept"> key.
■ Force the reloading of the deck for dynamic data.
Example 13-3
<meta http-equiv="Cache-control" content="no-cache" forua="true"/>
<meta http-equiv="Cache-control" content="must-revalidate" forua="true"/>
Example 13-3 shows how to force a reloading of the deck each time the card is
accessed in the forward or backward direction.
