CURLOPT_SSL_SESSIONID_CACHE (3) - Linux Man Pages
CURLOPT_SSL_SESSIONID_CACHE: enable/disable use of the SSL session-ID cache
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.
Added in 7.16.0
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
