如果缺少上下文，如何重定向到“维护模式”页面

Question

I have a webapp deployed with a war archive on a tomcat 6 server. There is a clean way to instrument Tomcat to redirect to a "Maintenance Mode" page if my webapps is undeployed?

I mean some sort of Tomcat component that dinamically intercept all request to my webapp and redirect them to another webapp (maybe ROOT) page to inform my users that the application is temporarily down.

安装apache httpd的 ，它使用Tomcat连接到代理的请求，Tomcat和Apache配置HTTPD作为五百零三分之四百零四错误页面，显示维护页面。
