I would get a situation where both the HTTP code and the return code from
libcurl are 0? 2 examples where this has happened (4 total out of about 450
attempts):

Both were regular GET requests. No discernable pattern here, just happens
sporadically. Otherwise I get a 200...

Got: http://www.kaosarts.com/ with code 0
pretransfer_time: 1.53964 req size: 174 head size: 0
download speed: 0 upload speed: 0 download size: 0 upload size: 0

Source fragment:
                char *error_buffer;
                long return_code;
                string return_string;
                int curl_status;
                
                error_buffer=new char[CURL_ERROR_SIZE];
                // Setup error buffer for result
                curl_easy_setopt(curlhand, CURLOPT_ERRORBUFFER, error_buffer);

                time(&start_time);

                // Get the URL
                curl_status=curl_easy_perform(curlhand);

                   curl_easy_getinfo(curlhand, CURLINFO_HTTP_CODE, &return_code);

                return_code=(curl_status ? curl_status+1000 : return_code);

                if(!ok()) return_string=error_buffer;
                
                delete [] error_buffer;
                
                // Get all that good info
                curl_easy_getinfo(curlhand, CURLINFO_HEADER_SIZE, &header_size);
                curl_easy_getinfo(curlhand, CURLINFO_REQUEST_SIZE, &request_size);

                curl_easy_getinfo(curlhand, CURLINFO_PRETRANSFER_TIME, &pretransfer_time);

                cout << "Got: " << url << " with code " << return_code << endl
                        << "pretransfer_time: " << pretransfer_time << " req size: " <<

                return;

                        return FALSE;
                else
                        return TRUE;
        }
