Liferay Session Timeout

In this tutorial, we will look into Liferay session timeout. Liferay session time out has set to 30 minutes by default and loaded from below files:

1. portal-ext.properties:  The below property will be used to set session timeout. This value is   always overridden by the value set in web.xm and changes will not take effect if there is session timeout entry in web.xml

    session.timeout=30

  2.  web.xml:    session time out is defined in web.xml and will take precedence over the portal-ext property file. You can verify the method checkWebSettings in MainServlet file:

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