I'm allready succesfully ussing reverse proxy to internal sever behind apache based on a named base virtual host.
I'm trying to do the same thing for ssl for a long time now with no luck.
What I'm trying to achive is that <a href='https://abc.com' target='_blank'>https://abc.com</a> will go trough freesco apache and when <a href='https://vnc.abc.com' target='_blank'>https://vnc.abc.com</a> it will forward de ssl request to my internal vnc repeater.
I know apache 2 has de sslproxyengine.
And there is something that can be done with ip allias in 1.3 but until now no luck.
