I have an easy handle (used via the multi interface) on which I have set

If either a direct connection or a CONNECT via a proxy fails, I get notified
via CURLE_HTTP_RETURNED_ERROR. When handling this, how do I know which one
of CURLINFO_RESPONSE_CODE and CURLINFO_HTTP_CONNECTCODE to consult to get
the relevant http status to report back to the user? Perhaps I should just
check both and hope that exactly one is non-zero (as is probably the case
for the first connection on an easy handle)?
They can also both be non-zero, if CONNECT succeeds and the HTTP request gets
an error.
You can actually check the transfer return code because FAILONERROR only
affects the actual request to the server and not the CONNECT to the proxy, so
a failed CONNECT will cause a CURLE_RECV_ERROR.
