You can modify the opendoc.htm file (in <QlikView install dir>\Server\QlikViewClients\QlikViewAjax) to contain a script that makes an AJAX call to prevent the session from idling. Changing opendoc.htm isn't supported by QlikTech, though. The below script should be added to the <head> section of opendoc.htm; it pings the server every 20 minutes for 2 hours. Alternatively, you can use the setInterval() function instead of setTimeout(), and this will ping the server forever... the downside is it will prevent all sessions from becoming idle, which might not be something you want.
<script type="text/javascript">
/* This script will ping the server every 20 minutes (for 2 horus) after opening the page to prevent a session from
from going idle, which normally will happen after 30 minutes due to a bug. This will give the
user 150 minutes to be idle after opening the report. -- jcoon 2012.11
