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 connections that libcurl may keep
       alive in its connection cache after use. 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 connection present in the cache to
       prevent the number of connections from increasing.

       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

       This functionality affects all supported protocols

EXAMPLE

       int main(void)
       {
         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);
         }
       }
