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  behaviour. 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 con-
     nections.

     If you already have performed transfers with this curl  han-
     dle,  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

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);
     }
