Tomcat共享Session并且通过Memcached集中管理

【multi-war share the same session OK】=>loadbalacne的前提是每个节点是对等的
/////////////begin/////////
>>>${Tomcat_home}/conf/context.xml =><Context ... sessionCookiePath="/">
>>>${Tomcat_home}/conf/server.xml=>session need to be managed by memcached

此处/bb和/ee应用可以共享session，通过memcached对session进行集中管理。
