Specifies the type of SSL connection.
|Use the SSLSocket constant names for ConnectionType, and not the integer values so that the IDE can warn you when constants are removed or deprecated.|
Set this property by assigning a SSLConnectionTypes value to it.
The default is TLSv1. If you need to change the connection type, close the connection first.
This example changes the connection type to TLSv1.
