This list is not the appropriate place for questions regarding your
ecommerce application.  Setting the values for Horde's session variables
will ensure that the expired session files are deleted in /var file system
if that is where you store your sessions.  Another thing to make sure you
have properly setup is the values for session.gc_probability,
session.gc_divisor and session.gc_maxlifetime in your PHP.INI file normally
located under /etc/php5/apache2 if you use apache.  

Regarding your other application, perhaps you should separate the location
of stored session files for this so that they do not interfere with your
Horde sessions.  You can look at the PHP manual for session.save_path 

You should not setup a cron job to just delete ALL session files every so
often.  You can however setup a cron job that deletes file older than a
certain number of days based on how long you want a session to last.  There
are examples of this online.
