Updated : November 26, 2021
Source : libcurl 7.82.0
Note : curl_easy_getinfo options
NAMECURLINFO_NUM_CONNECTS − get number of created connections
SYNOPSIS#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_NUM_CONNECTS, long *nump);
DESCRIPTIONPass a pointer to a long to receive how many new connections libcurl had to create to achieve the previous transfer (only the successful connects are counted). Combined with CURLINFO_REDIRECT_COUNT(3) 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.
