I have Apache running on our main server inside a LAN behind a hardware firewall. Port 80 is forwarded through to it. It has a number of virtual servers etc all running locally on it using the ServerName directive.

I now want to run a company website locally. Problem is that it's ASP based and it looks like Apache can't really handle that - if it could, that would probably be the favoured solution.

So I really need to run IIS. I can't really run it on port 80 locally since it will mess the other services up.

What I need is to run IIS on another port and redirect any requests for www.company.com to that port OR run IIS on another machine and redirect port 80 and www.company.com through to it. I can't use the simple Redirect method since it requires the second server to be visible. I want everything to go through the current webserver and port and be invisibly (to the outside) redirected.

I can't seem to find what I want in the Apache documentation.

Any ideas?
