Reverse Proxy Server?

I hope this is the right place to post this...

We develop numerous internal web applications that we occasionally need to publish to customers. In very sensitive scenarios, we will force them to use a VPN to connect. In others, we just publish a server/app beyond the firewall. I would like to see a solution that could handle both scenarios easily, and would not require that I put multiple servers or apps outside the firewall.

My thoughts were to use something like what Anonymizer (http://www.anonymizer.com) does. Essentially, it just forwards requests for you, and returns the information to you. So, if someone out there went to http://mydomain.com and logged in, they could then go to http://mydomain.com?server=someserver (or something like that). Does anyone out there know of a tool like this that is already available? I would prefer a Windows platform, but 'nix is acceptable.
