 * Retrieve the number of new connections libcurl had to create to achieve
 * the previous transfer (only the successful connects are counted).
 * Combined with +redirect_count+ you are able to know how many times libcurl
 * successfully reused existing connection(s) or not.
 *
 * See the Connection Options of curl_easy_setopt(3) to see how libcurl tries
 * to make persistent connections to save time.
 *
 * (requires libcurl 7.12.3 or higher, otherwise -1 is always returned).
