I\'m trying to send payment data to SagePay and, as they are turning off SSL, it needs to be sent using TLS.
The code I have is as follows:
Option 9 is WinHttpRequestOption_SecureProtocols which is
9
SSL 2.0: 0x0008 SSL 3.0: 0x0020 Transport Layer Security (TLS) 1.0: 0x0080
So
httpRequest.option(9) = &H80
