会话超时自动

Question

I understand that the session timeout is for finding out an idle app and ending that particular session.
I have commented the session-timeout tag in the web.xml. Also I have not set any session timeout in my application anywhere else like maxInactiveInterval().

But my session is expiring nearly after 2 or 3 hours. Is there any automatic session timeout in Tomcat?
I have observed the above phenomenon in both Tomcat 5 & 7. Please help... I don't want a timeout happening for some purpose here.

Answer 1

yes.In tomcat web.xml file see this code:

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

By default it set to 30 minutes. if you dont want session expiry simply put as 0 instead of 30.

session statics in tomcat.

Answer 2

If you don't want a timeout happening for some purpose:

<session-config>
    <session-timeout>0</session-timeout>
</session-config>

should result in no timeout at all -> infinite
