CURLOPT_SSL_SESSIONID_CACHE(3) curl_easy_setopt options CURLOPT_SSL_SESSIONID_CACHE(3)NAME
CURLOPT_SSL_SESSIONID_CACHE - enable/disable use of the SSL session-ID cache
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSL_SESSIONID_CACHE,
long enabled);

SSL implementations in the wild that may require you to disable this in order for you to succeed.
