Forward http request with client certificate to outside server with mutual ssl validation

Help!
1

Hi everybody,

I’m looking for how send a client certificate to outside server with ssl validation but I don’t found it in documentation and no examples im internet, usually appears only example with openssl and s_client command.

Many examples of how create a server with client validation but I want create a client with haproxy to consume it.

I like listen in haproxy.cfg some port, by example 81, and send the request to https://outsideserver.com:443 adding client certificate.

Any example to do this?

Thanks so much in advance.

Xavier.
