我正在开发一个项目，我需要在两个不同的 tomcat 上复制会话。我将 Nginx 配置为负载均衡器。配置两个tomcat来创建两个不同的节点。
我的要求：假设两个节点正在运行，并且节点一的会话在节点二中复制。最终用户正在从节点一获得响应。如果节点一关闭，则用户将无法退出会话并继续使用相同会话的节点二。
现在发生了什么：两个节点正在运行，并且会话已复制到两个节点。用户从节点一获取响应。节点一关闭，用户收到会话结束消息。
我配置了 tomcat 集群机制，如来自此 site 的 tomcat 文档 我配置了tomcat 1的
server.xml<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"
channelSendOptions="6">
<Manager className="org.apache.catalina.ha.session.BackupManager"

一件有趣的事情是相同的配置适用于另一个项目，但不适用于我的项目。我已经拼命寻找解决方案四天了。找不到任何可以让我放松的东西。
有几种可能的解决方案：
我对 Nginx 不熟悉，但似乎 Nginx 没有根据 jessionid 重定向请求。
您还可以使用memcache会话管理器来解决您的问题。请参考链接的描述 memcache 会话管理器
