Add trusted CA without adding to Windows certificate tool

[matthewg42]

I need to use Ginger from a Citrix machine to test web service calls. The web service provider uses a server certificate that is issued by a customer CA which is not in the Trusted CA list in the Windows certificate store on the Citrix machine. I anticipate Ginger failing to establish TLS sessions because it cannot verify the server certificate.

I have no ability to add the customer CA to the Citrix machine's trusted CA list since this machine is administered by a third party who will very likely refuse to do it (as it would affect all users of the Citrix system).

Is there a way to allow these connections to proceed? If I were using curl, I could use the --cacert option to tell curl to allow CAs from a specific file, or use the --insecure option to skip server certificate checks. Is there some analogue in Ginger?
