I have figured out some of my problems but a few remain if anyone has
any ideas.

Currently, a client on the Internet can use HTTPS to the proxy and  the
proxy will talk HTTP to the webserver.  This works ok.

INTERNET-----https-----+-----http-----FIREWALL-----http-----WEBSERVER
                                        P
                                        R
                                        O
                                        X
                                        Y

However, if I also enable https from the proxy to the webserver, the
internet client can't connect:

INTERNET-----https-----+-----https-----FIREWALL-----https-----WEBSERVER
                                        P
                                        R
                                        O
                                        X
                                        Y

Yet is I disable https altogether, the internet client gets through
fine:

INTERNET-----http-----+-----http-----FIREWALL-----http-----WEBSERVER
                                        P
                                        R
                                        O
                                        X
                                        Y

If I bypass the proxy server, the internet client using https can get
through to the webserver ok:

INTERNET-----https-----FIREWALL-----https-----WEBSERVER

If I use https via browser from the proxy server itself (below) to the
webserver, that works:


+-----https-----FIREWALL-----https-----WEBSERVER
                                        P
                                        R
                                        O
                                        X
                                        Y

However, If I use http from the internet cleint to the proxy then https
(as above) to the webserver, it doesn't work:

INTERNET-----http-----+-----https-----FIREWALL-----https-----WEBSERVER
                                       P
                                       R
                                       O
                                       X
                                       Y

Thus I am unable to determine WHERE my problem is.  Anyone got any
explainations or experience with this?  Thanks for any assistance.

Kevin
