By default, visitor sessions timeout after 30 minutes of inactivity. How can I change this setting?
In Urchin 6, the default UTM (Urchin Traffic Monitor) session timeout is set to 30 minutes of inactivity in both the FreeBSD/Linux and Windows installation packages. This setting can be changed by modifying the file "urchin.js" which is located at C:\Program Files\Urchin6\util\utm\urchin.js in Windows and /util/utm/urchin.js in FreeBSD/Linux.
Near the top of this file is the following user timeout definition:
var _utimeout="1800"; // set the inactive session timeout in seconds
Changing the timeout value from 1800 seconds to 3600 seconds, for example, would extend the user tracking time period from 30 minutes to one hour.
