Set Session Timeout

In a web application, you can set session timeout in three ways:

1. Configure in the web. xml file: the unit is minute and the range is for sessions of all users in the project.

<Session-config> <session-Timeout> 10 </session-Timeout> </session-config>

2. Set in the program code: the unit is second, and the range is for the session of the current user

Session. setmaxinactiveinterval (900 );

3. Set conf \ WEB. xml on the Tomcat server. The unit is minutes, And the range is for all user sessions of all projects on the server.

<Session-config> <session-Timeout> 30 </session-Timeout> </session-config>

Conclusion: Generally, the first method is more suitable.
