Either:
1. Use the multi API, or
2. Create a share object (CURLSH), set CURLSHOPT_SHARED to CURL_LOCK_DATA_SSL_SESSION, and set the easy handle to use the share object. Don’t forget to set the lock/unlock functions for the share object.

Also, if CURLOPT_SSL_SESSIONID_CACHE is set to 0L in your easy handle, it doesn’t matter what you do; sessions will never be re-used. Make sure this is set to 1L unless you have a good reason for not wanting to re-use sessions. I think it’s 1L by default.
