I can use the GUI to connect to scanftpaws.performancematters.com using FTP with explicit TLS, but only if I restrict the TLS version to 1.2 and UNCHECK the “Reuse TLS session ID for data connections” box in Advanced Site settings. That's fine.

The problem is that I need to do the same using .NET. I can restrict the TLS version using SessionOptions.AddRawSettings, but I don't know how to uncheck “Reuse TLS session ID for data connections” in .NET. Can anyone tell me? Code:


sessionOptions.AddRawSettings("MinTlsVersion", "12")
sessionOptions.AddRawSettings("MaxTlsVersion", "12")
sessionOptions.AddRawSettings("ReuseTlsSessionId", "0")

I think AI invented that third line of code. I don't find that raw setting in the documentation. The error I'm getting is:
