Mutual SSL authentication proxying to downstream service.

Hello? I have an issue with proxying client certificate to downstream service. I have service behind Spring Cloud Gateway (SCG) which need/want mutual tls authentication. But unfortunately when user executes requests through SCG mutual tls do not happen. On browser sight I did not get any client certificate request, so I assumed that it was not forwarded as a response from downstream service to a browser. I watched carefully on #852, #1091 and on your documentation. And seems that you solve how to make mutual tls from client to SCG and also from SCG to downstream service. But both of them not allow to make mutual tls from client to downstream service through SCG. Have you any ideas about how to solve it? Maybe it needs additional SCG Filter for proxying mutual tls auth ? Or any else solution? Thank you!

Start with the TLS/SSL documentation and related issues #852 and #1091 to understand the existing client-to-gateway and gateway-to-downstream configurations. Then identify the gateway entry points involved in forwarding client certificates; done would require a confirmed design or documented solution for mutual TLS between the client and downstream service through the gateway.
