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

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);
         }
       }
