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 simultane‐
       ously open persistent connections that libcurl may cache  in  the  pool
       associated  with  this  handle. The default is 5, and there is not 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 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  curl_multi_setopt(3)  and  the
       CURLMOPT_MAXCONNECTS(3) option.

DEFAULT
       5

PROTOCOLS
       Most

EXAMPLE
       CURL *curl = curl_easy_init();
       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);
       }

AVAILABILITY
       Always

RETURN VALUE
       Returns CURLE_OK
