https redirect error

[xxrlzzz]

hey guys, I'm using this library to do little project, and with a problem.

Problem Description:

When I want send http request with Client, it may fail to get response when the server require redirect from http request to https request.

My way to resolve

I found I need to call set_ca_cert_path, but it lost during redirect, copy_settings don't copy ca cert path, and I found client_cert_path_ and client_key_path_, but no else place was using this.
SSLClient actually using ca_cert_file_path_ and ca_cert_dir_path_. I don't know relation between them.
Currently I'm setting ca_cert_file_path_ and ca_cert_dir_path_ in copy_settings. It works for me. It may be a bug or just my wrong usage. looking for your reply.
