Reverse SSL proxy for jetty

Hi,

I’m trying to use nginx as a reverse-proxy in front of a jetty (running
artifactory^1).

HTTPS → NGINX → HTTP → Jetty

In plain HTTP it works like a charm, but HTTPS fails. Jetty doesn’t
recognizes the $scheme. I tried

    add_header              Front-End-Https on;
    proxy_set_header        X-Forwarded-Proto https;

Jetty or Artifactory ignores the protocol and some links are calculated
as http:// others as relative links (which works). For Jetty it should
work as stated here^2 .

May be there is something magic I can’t see?
Can you share your config

Thanks for your help
