reverse proxy: do I really have to store ssl certificates on the proxy ?

[iw2lsi]

Hi,

  I'm newbie so maybe this is a stupid question... sorry!

I'm using a rPI to reverse proxy http services to several other rPI
according to the domain and/or host names... now I'm switching to https and
I wonder if I can keep the ssl certificates and keys on the destination
machines or if I really have to put them on the machine that is managing the
(reverse) proxy.

   thanks for any hints

          Giampaolo
