Salut,
Using the Microsoft Internet Transfer Control ActiveX in LabVIEW (as mentioned earlier), you should be able to send and receive data from a server using the HTTPS protocol. You will have to use the "Execute" method, and then use the "GET" and "PUT" commands, for example.
The following MSDN has some good info' on using this ActiveX control and its methods.

Hope this helps.
Salut,
Khalid
