问题
It is possible to export/forward the client certificate to the backend services using Zuul as a proxy/load balancer? I finally have a working example of zuul with spring-cloud using https and forwarding requests to a secure service on the backend using https as well. Now I need to forward the client's certificate information in addition to using https. You can do this with Apache and Tomcat using the SSLOptions +StdEnvVars/+ExportCertData, which adds the information to the headers, but I don't see how to do this with Zuul. Does anyone know how you can do this?
