CAS ajax请求无法获得响应

Question

我正在使用CAS进行单点登录，在我的cas客户端中，我有一个包含几个js文件的main.html页面，而一些js文件将触发ajax调用，但是当我首先键入http://localhost:8443/casClient/main.html时向我显示登录页面，登录后，CAS服务器将重定向到main.html，所有js文件和css文件都可以无条件加载，但是ajax webservice调用挂起，没有任何响应几分钟。

当我重新启动CAS客户端并在浏览器中逐个输入webservice url时，它可以显示我正确的响应，但是当我再次在浏览器中输入main.html时，所有ajax webservice将再次挂起。

任何人都可以帮我解决那里的错误吗？

我附上了我的web.xml
