Spring Why session get expired before session-time

问题:

I am using Spring security authentication and after successful logis is session set. I have configured session-timeout on 10 minutes, but session is removed after few minutes. I don't know why.

Here is debug output:

2013-09-13 12:34:29 DEBUG HttpSessionEventPublisher:83 - Publishing event: org.springframework.security.web.session.HttpSessionDestroyedEvent[source=org.apache.catalina.session.StandardSessionFacade@5d67c24a]

web.xml

<session-config>
    <session-timeout>10</session-timeout>
</session-config>

Session timeout can be overridden by various means. See http://docs.oracle.com/javaee/1.3/api/javax/servlet/http/HttpSession.html#setMaxInactiveInterval(int). Make sure there isn't anything else that is overriding it (Web/App server, framework, ...).
