Page navigation reactions
When a person enters a page, you can control what they see. This is particularly useful if you want the page to be different when someone returns to a page they have just left. The tags used are <onenterforward> and <onenterbackward> which are used to differentiate between entering a page for the first time, and returning to it.

An example follows...

<?xml version="1.0"?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN" "http://www.wapforum.org/DTD/wml_1.1.xml">
<wml>

<card id="MainCard" title="This is a first card" onenterbackward="#returncard">
<timer value="50"/>
<p align="center">
Hi, you have never been to this page
<br/>
<a href="#card2">Go to page two</a>
</p>
</card>

<card id="card2" title="This is the second card">
<p align="center">
This is the second card
<do type="accept" label="back">
<prev/>
</do>
</p>
</card>

<card id="returncard" title="This is the second card">
<p align="center">
You returned to the first page, but this is displayed instead !
</p>
</card>
