By default, Strategy Library session will expire after a user is idle for 30 minutes. This timeout is controlled by the <session-timeout> parameter in web.xml file located in <tomcatdeployment>/webapps/StrategyLibrary/WEB-INF'.
In order to change the idle timeout for Strategy Library following steps need to be taken:
1. User with adequate privileges should edit the web.xml file
2. Locate the <session-config> element
3. Enter a new timeout (in minutes) between <session-timeout> and </session-timeout> tags (as shown below)
4. Tomcat has to be restarted to apply the change.
