I have an easy handle (used via the multi interface) on which I have set
CURLOPT_FAILONERROR.
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)?
I've scanned curl_easy_getinfo() -- possibly too quickly -- and not spotted a
way to detect whether a failure is due to a proxy, or even whether a connection
involves a proxy.
I can use CURLOPT_ERRORBUFFER to get a human-readable message, and probably I
will write that to a log in verbose mode. However in this application, error
handling is done by shoehorning stuff into errno, so primarily I want to find
the actual numeric HTTP status code so I can translate it into an appropriate
errno equivalent. Hence the question above.
Cheers,
John
