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. # %PROTOCOLS% # EXAMPLE ~~~c int main(void) { CURL *curl = curl_easy_init(); if(curl) { CURLcode res; curl_easy_setopt(curl, CURLOPT_URL, "https://example.com"); curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L); res = curl_easy_perform(curl); if(res == CURLE_OK) { long connects; res = curl_easy_getinfo(curl, CURLINFO_NUM_CONNECTS, &connects); if(!res) printf("It needed %ld connects\n", connects); } curl_easy_cleanup(curl); } } ~~~ # %AVAILABILITY% # RETURN VALUE Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
