Sending SSL Client Certificate upstream

[Dave Marchevsky]

Hello,

I am modifying my upstream servers so that they require client certificates
from clients, which are other backend apps making service calls and nginx
proxying for public requests. Public requests come to nginx without a client
certificate and are proxied upstream, but since the upstream server requires
a client cert they fail. 

I'd like to be able to provide a client cert to nginx (from local file) to
send upstream for authentication. Is this possible? 

Thanks,
Dave
