First, the 405 response code from the proxy is not considered to be a
"connection error code" with libcurl.

The CURLINFO_RESPONSE_CODE is the last response code from a FTP or HTTP
request. But since in the case of CONNECT, you may get two response codes (one
from the proxy and one from the remote server), you can get the CONNECT one
with CURLINFO_HTTP_CONNECTCODE.

The CURLINFO_RESPONSE_CODE doesn't change meaning when errors occur, it is
still the response code from the server. If no response has been received,
you get zero back.

CURLINFO_OS_ERRNO might be what you want.
