The HTTP version to use.
This property specifies the HTTP version used by the connector. Possible values are:
- "1.1" (default)
When using HTTP/2 only secure (TLS/SSL) connections are currently supported. Attempting to use a plaintext URL with HTTP/2 will result in an error.
If the server does not support HTTP/2 the connector will automatically use HTTP/1.1 instead. This is done in order to provide compatibility without the need for any additional settings. The AllowHTTPFallback setting controls whether this behavior is allowed (default) or disallowed.
HTTP/2 is supported on all versions of Windows. If the Windows version is prior to Windows 8.1/Windows Server 2012 R2 the internal security implementation will be used. If the Windows version is Window 8.1/Windows Server 2012 R2 or later the system security libraries will be used by default.
