CURLOPT_MAXCONNECTS(3)     curl_easy_setopt options     CURLOPT_MAXCONNECTS(3)

NAME
       CURLOPT_MAXCONNECTS - maximum connection cache size

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAXCONNECTS, long
       amount);

DESCRIPTION
       Pass a long. The set amount will be the maximum number of
       simultaneously open persistent connections that libcurl may cache in
       the pool associated with this handle. The default is 5, and there isn't
       much point in changing this value unless you are perfectly aware of how
       this works and changes libcurl's behavior. This concerns connections
       using any of the protocols that support persistent connections.

       When reaching the maximum limit, curl closes the oldest one in the
       cache to prevent increasing the number of open connections.

       If you already have performed transfers with this curl handle, setting
       a smaller _MAXCONNECTS&section=3">CURLOPT_MAXCONNECTS(3) than before may cause open connections
       to get closed unnecessarily.

       If you add this easy handle to a multi handle, this setting is not
       acknowledged, and you must instead use _multi_setopt&section=3">curl_multi_setopt(3) and the
       _MAXCONNECTS&section=3">CURLMOPT_MAXCONNECTS(3) option.

DEFAULT
       5

EXAMPLE

       if(curl) {
         CURLcode ret;
         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
         /* limit the connection cache for this handle to no more than 3 */
         curl_easy_setopt(curl, CURLOPT_MAXCONNECTS, 3L);
         ret = curl_easy_perform(curl);
       }
