CURLOPT_FORBID_REUSE(3)    Library Functions Manual    CURLOPT_FORBID_REUSE(3)

NAME
       CURLOPT_FORBID_REUSE - make connection get closed at once after use

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FORBID_REUSE, long close);

DESCRIPTION
       Pass a long. Set close to 1 to make libcurl explicitly close the
       connection when done with the transfer. Normally, libcurl keeps all
       connections alive when done with one transfer in case a succeeding one
       follows that can reuse them. This option should be used with caution
       and only if you understand what it does as it can seriously impact
       performance.

       Set to 0 to have libcurl keep the connection open for possible later
       reuse (default behavior).

DEFAULT
       0

PROTOCOLS
       This functionality affects all supported protocols

EXAMPLE
       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
           curl_easy_setopt(curl, CURLOPT_FORBID_REUSE, 1L);
           curl_easy_perform(curl);

           /* this second transfer may not reuse the same connection */
           curl_easy_perform(curl);

           curl_easy_cleanup(curl);
         }
       }

AVAILABILITY
       Added in curl 7.7
