EP IVIEW for WD4A: HTTPS and POST parameter

Hello expert,
I have to create a Portal IVIEW for WebDynproABAP with the following characteristics:
• called from an HTTPS request,
• The HTTPS request transfer parameters as a POST request (parameter <UNAME>).

How can i set the HTTPS mode ?
How can i receive the POST parameters and pass them to the WebDynproABAP?

Thanks a lot.

Regards
