SSL: client cert support

[rohitjoshi]

Is there anyway to specify client certificate/key while connecting to backend/upstream server using SSL?

[hamishforbes]

Not at the moment. The underlying (ngx.socket.tcp)[https://github.com/openresty/lua-nginx-module#tcpsocksslhandshake] implementation doesn't support client certs.
When / If it does adding support to resty-http should be fairly easy.

Still unavailable?

If the upstream is not variable, try to define a proxy block and use Nginx's proxy_ssl_certificate_key and proxy_ssl_certificate as workaround.
