Reverse proxy & my CA certificate

[filebackup]

Hi all.
My website's work process is the bleow:
client_browser:443 -> nginx_reverse_proxy:443 -> nginx_webserver:443

------------------

in my nginx webserver config file, I setup some ssl options:
ssl_verify_client	on;
ssl_verify_depth	1;
......


I have two questions:
1. Would the nginx webserver check nginx reverse proxy's CA
certificate?
2. If would check, is there has an option to setup nginx reverse proxy's
CA certificate?

Thank in advance.
