IIS on Windows 2000 Server

Hi Paul,

My understanding of your post is that you want to access copmuter B's web
application from Internet. Is this correct?

If so, this is not possible with host headers, unless your router has this
capability. Routers usually understand only IP and port. And what you want
to do is forward the request to an internal machine based on host header.

Usually you can solve this using a reverse proxy. ISA Server can do this,
and there are third-party products as well. Octagate has a product, and
they also have a very good picture explaining how this works:

IIS cannot act as a reverse proxy (i suppose you could write an ISAPI
filter for this purpose).

Hope this answers your question.
