IIS7 ARR using HTTPS only from ARR to content server

IIS7 ARR using HTTPS only from ARR to content server

I have an IIS server set up as a reverse proxy, using the ARR component.
Currently it works over HTTP on port 80, so no coplications there.
What I want to achieve is so the clients will contact the proxy using
normal HTTP requests, and the proxy will contact the content server using
HTTPS over SSL. Is it possible?
BTW, Searching Google produced threads talking about "SSL Offloading"
feature which is the opposite of what I'm looking to accomplish - it
enables the clients to contact proxy with HTTPS over SSL and the proxy to
contact the content server using normal HTTP.
Thanks in advance, Avi.
