Make sure those variables below are properly handled, as before.
The SSL control should only be invoked if requested, otherwise NetCurl should fall back to defaults as it protects sites from failing in calls when for example hardening has been done (open_basedir).
* @var bool $testssl
* For PHP >= 5.6.0: If defined, try to guess if there is valid certificate bundles when using for example https links (used with openssl).
* This function activated by setting this value to true, tries to detect whether sslVerify should be used or not.
* The default value of this setting is normally false, since there should be no problems in a properly installed environment.
private $testssl = true;
private $testssldeprecated = false;
