By default, Tomcat attempts to persistently save a session in a file format if the web application or Tomcat is stopped. When Tomcat is restarted, it will recreate the prior session at startup of the web application. WebOffice 10 R3 does neither use nor support this function. The user can deactivate these settings by changing the configuration of the web application:
Navigate to <Tomcat installation folder>\conf\Catalina\localhost and create an empty XML file named as your web application. e.g. WebOffice.xml. Edit the XML file and insert the lines:
<?xml version="1.0" encoding="UTF-8"?>
<Context>
<Manager pathname="" />
</Context>
Restart Apache Tomcat.
