原因：客户在应用服务器上层有nginx，https://A请求通过nginx转发是带了X-Forwarded-Proto头的，但是应用服务器重定向请求B是没有X-Forwarded-Proto头，默认就按http处理请求了，之后http://B请求又进入nginx,这时候https://A请求没有达到最终的目的地故触发了异常
解决方案：在domains/mydomain/config/domain.xml对应的实例配置中的network-listener新增属性 valve-class-name="org.apache.catalina.valves.RemoteIpValve"，修改后重启中间件，如果是独立实例就在重启中间件后，再重启实例
