很多时候明明在服务器上关闭了TOMCAT,但是客户端的表示SESSION仍然在线,<Manager className="org.apache.catalina.session.PersistentManager"
debug="0"
saveOnRestart="false"
maxActiveSessions="-1"
minIdleSwap="-1"
maxIdleSwap="-1"
maxIdleBackup="-1">
<Store className="org.apache.catalina.session.FileStore"/>
</Manager>
Manager块是要放到相应的Application的Context下.
