Re: Getting the HTTP response code following a 100 Continue

Olivier is correct, this is what I am seeing, also. In order to view the
final status code, I had to implement a header function and manually parse
out the 2nd response code when the request is completed. Since, per the
spec, a final status code is required in all cases, as far as I can tell, it
seems reasonable to make the 2nd response code the value returned from
CURLINFO_RESPONSE_CODE in all cases. In my usage of Expect: 100-Continue,
the client doesn't really care about the 100 response (other than to trigger
the actual upload), it seems to be mostly for the benefit of the server in
order to preemptively cancel a request that it knows it will ultimately
