How to Change the Session Timeout Value

Issue

This value is set on the [App_Server_HOME]/webapps/ROOT/WEB-INF/web.xml file. You can manually adjust the property below, replacing X for the timeout value in minutes.
```
<session-timeout>X</session-timeout>
```
Further, there is a session timeout portal property (see below) as well that can be added to the portal-ext.properties, but usually is overridden by the value set in web.xml. Also, the portal-ext property will sometimes only take effect if there is no <session-timeout> property set on the web.xml file.
```
 # Specify the number of minutes before a session expires.
 #
 # Env: LIFERAY_SESSION_PERIOD_TIMEOUT
 #
 session.timeout=15
```

Alternative option to adjust session timeout is creating an Ext plugin to modify the web.xml
Additionally in some versions of DXP 7.4 the session timeout must be set as the same value in both the web.xml file as well as the portal-ext properties file in order for session timeout to work correctly.
And for DXP 7.1 please refer to the steps here
Restart the DXP instance to fetch the new changes

Note: There are some application servers where the session-timeout is not correctly retrieved from the web.xml even if it is correctly specified.
