Re-direct web URL to Local Server

This is my first attempt to enable a web application so excuse me if a
use the wrong terminology.

what I am attempting to do is enable a web application that is running
on a local server running IIS from our main internet web server.
Basically, our main web-site is being hosted our main web-site. We
would like to re-direct a certain url from this site to another web
server to run a specific application.

For instance, assume www.mainsite.com is the primary site and is
currently accessible through the web. We would like all requests for
www.mainserver.com/nbc to be re-directed to another web server running
on our domain. This web server does not have an external IP address,
but can be accessed internally from the main web server. Is this
possible? If so, what changes need to be made to the web server,
router, and/or proxy server? If not, will we need to obtain an
external IP for the additional web server?

Not directly. You can server content, but if a system can't reach the
server, it can't be served a web page from it. You'd need to reverse
proxy the internal web server, which IIS doesn't do.

Public IP, NAT'd IP, forwarded port or whatever, it has to be
reachable by the client system.
