Hi Daniel and All,
 
Oh..I'm sorry I didn't occur to me this would be in the known_bug list.
 
Incidentally my co-worker discovered an alternative workaround although we don't completely understand why it works:
curl_easy_setopt(mCurlHandle, CURLOPT_NOBODY, (long) 0);
 
Apparently, NODOBY - 0 makes curl uses PUT in the request, insated of HEAD. And it works even if CURLOPT_FAILONERROR enabled. (I verified for Digest authentication).
 
The server is Apache2 on RH9. (if that matters).
 
Thank you,
mitz

You're experiencing a bug: CURLOPT_FAILONERROR doesn't work with a non-Basic
authentication! This is in fact mentioned in the KNOWN_BUGS document.

Fixing this flaw is not trivial, and this bug is still present in the current
development version.

The work-around is simply to not use CURLOPT_FAILONERROR for these cases.
