CURLOPT_MAXCONNECTS - maximum connection cache size
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAXCONNECTS, long
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 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
CURL *curl = curl_easy_init();
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);
