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  is  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  is not much point in changing this value unless you are perfectly aware of
       how this works. 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

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);
         }
       }
