Hi Serge,

I think in forward Proxy mode, most of the proxy servers do an SSL
tunneling and donot actually read the https requests. So, I donot
think this will be the case. This is because in forward proxy we have
the Proxy server at the client's end and so we may not need the
encrypted link between the proxy server and the client as proxy server
is in the same network as clients.. It is between the Proxy server and
the main servers ( hosting websites) that we have the SSL link.Because
the proxy server connects to the main server through the internet.

What you are talking about is probably the reverse proxy mode.

Correct me if I am wrong.

Thanks
