The session timeout defines the validation period of a session. In the portal environment, such as eXo Platform, it is highly recommended that all web applications have the same session timeout value.

The session timeout is configurable individually for each web application in the web.xml file:

<session-config> 

    <session-timeout>30</session-timeout> 

</session-config>

The value is in minute.

In Tomcat, you can set session timeout globally by modifying the conf/web.xml file.
