HA Proxy with SSL client authentication

[ddepaolis]

Greetings all, I've this scenario: two (Apache) webservers with same SSL certificate issued by our local CA (it's a wildcard certificate). There're clients which needs to do SSL strong authentication using their own certificates (each client has its own different certificate) issued by same local CA.

How can I setup HAProxy to be the VIP of this scenario ? I imagine it should be completely "transparent" when it happens SSL client authentication with beck-end web servers.
Thanks for any help or advice...
