Also set session timeout settings. 

In order to implement session timeout, you must update the following 3 files:

Apache Tomcat location\config\web.xml
Here you need to set the session timeout value: (example 5 minutes)
<session-config>
        <session-timeout>5</session-timeout>
    </session-config>
Apache Tomcat location\webapps\awi\config\uc4config.xml
Here you will turn off tcp keepalives
<tcpip_keepalive>0</tcpip_keepalive>
Apache Tomcat location\webapps\awi\config\configuration.properties
Here you will set:
closeIdleSessions=true

Then you must restart Apache Tomcat for these setting to take affect.
