CURLOPT_SSL_SESSIONID_CACHE - enable/disable use of the SSL session-ID cache
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSL_SESSIONID_CACHE,
Pass a long set to 0 to disable libcurl's use of SSL session-ID caching. Set
this to 1 to enable it. By default all transfers are done using the cache
enabled. While nothing ever should get hurt by attempting to reuse SSL
session-IDs, there seem to be or have been broken SSL implementations in the
wild that may require you to disable this in order for you to succeed.
CURL *curl = curl_easy_init();
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
/* switch off session-id use! */
curl_easy_setopt(curl, CURLOPT_SSL_SESSIONID_CACHE, 0L);
ret = curl_easy_perform(curl);
Added in 7.16.0
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
