将 SSL 用于应用程序时的会话超时
Posted
技术标签:
【中文标题】将 SSL 用于应用程序时的会话超时【英文标题】：Session timeout when using SSL for an application 【发布时间】：2013-04-26 06:03:53 【问题描述】：我们目前有一个 jboss 服务器，它有两个配置文件。每个配置文件都有不同的应用程序，应用程序 A 和应用程序 B 在配置文件中。当我们在 App B 中使用 SSL 时，App A 上会出现会话超时，反之亦然。有谁知道或知道为什么会发生这种情况。
在服务器中，App B 向 App A 发送远程 EJB 调用以获取数据。换句话说，App B 依赖于 App A。另外，为了启动 App B，需要启动 App A。
我们需要为 App B 启用 SSL，这是通过 IBE 配置文件的 JBOSS Web 部署文件夹中的 server.xml 文件完成的。
当同时使用 App A 和 App B（都没有 SSL）时，没有服务器超时但是当使用 App A（没有 SSL，因为我们不为 App A 使用 SSL）和带有 SSL 的 App B 时，有一个会话超时。一个例子
-
同时加载 App A 和 App B
登录应用 A（无 SSL）
在 App A 中访问屏幕或执行某些功能
转到 App B 并单击一个按钮以执行某些功能 (SSL)
App B 会话已超时
转到应用 A 并执行其他功能
应用 A 会话已超时
这是附加的Application A的server.xml
