I thought about that too. It seems like a lot to do to get a stack of DNs built. But you know
the OpenSSL code handles the I/O so well as is, I chose the lazy (smart) code reuse route.
I haven't even bothered to look at the FindCAList code. Also, yes a person can, with this
patch, in place shoot themself in the foot by requested CAs that he doesn't configure for

I am not sure I understand. The func ssl_init_proxy_ctx() calls the same ssl_init_ctx() that
ssl_init_server_ctx() does. And ssl_init_ctx() calls ssl_init_ctx_verify() which loads client
auth cert stuff. To take the proxy directive support out would cascade into more changes to
see if a function is executing for a proxy or not. Please clarify and I'll update the patch.
