Also, with (1) I see that when CURLOPT_CONNECTTIMEOUT was set to 10 seconds, and curl logs "Resolving timed out after 10001 milliseconds", CURLINFO_TOTAL_TIME reports more time, like 15 or 20 seconds, Is this normal? This is with the easy interface and libcurl 7.64.1 ------------------------------------------------------------------- Unsubscribe: https://cool.haxx.se/list/listinfo/curl-library Etiquette: https://curl.se/mail/etiquette.html
