ClientInfo.getUpstreamAddress() does not return IP as set in X-Forwarded-For header

[ebner]

The application is executed in Tomcat 8 using the Servlet connector, behind an Apache HTTPD which is configured as reverse proxy. The reverse proxy sets the X-Forwarded-For header correctly, but the method request.getClientInfo().getUpstreamAddress() returns the IP of the proxy, and not the IP as specified by X-Forwarded-For.

The header can be accessed directly using request.getHeaders().getFirstValue("x-forwarded-for", true) on the very same request, so something seems to be broken in the convenience method ClientInfo.getUpstreamAddress().

I am calling getContext().getParameters().add("useForwardedForHeader", "true") in the Restlet's createInboundRoot() method, I don't know whether that's needed for the Servlet connector though.

The Restlet version in use is 2.3.12 on OpenJDK 1.8.0_191.

In Restlet 3.0 we will be dropping support for Servlet to focus on deployment to cloud native architectures, microservices, service mesh, reducing the value of Servlet containers.
