Can I host two separate web servers on a LAN to the outside world through 1 IP address?

Question

I am a web programmer with a home web dev operation. I have multiple web servers in my house on a FIOS connection. I have my own domain pointed to my router through dyndns.org's custom domain service.

My ISP gives me ONE static IP address, which at the moment allows me to configure my router to direct outbound web traffic from one server through port 80 and another server through port 8080. This sucks because many companies block port 8080 these days causing some of my corporate clients to not be able to hit my second web server.

Is there any way for me to direct regular old port 80 web traffic to TWO SEPARATE web servers internally on my network using two separate host names?

For instance. I want http://webserver1.mydomain.com to hit one web server on my network, and http://webserver2.mydomain.com to hit another web server and have both sets of traffic served on port 80.

Is this even possible? If not, can I do a hack by programmatically routing traffic from one web server transparently to another?

For the record I run MS Windows Server 2008 IIS 7.0 stack, a D-link DIR-655 router, and use DynDNS for my domain needs.

The name of the solution you looking for is called reverse proxy'ing.
There are implementations in apache, squid and Mircosoft ISA Server.

If your adventurous you can always roll your own? or modify something like this to meet your your needs.

I've had customers using squid reverse proxy that's high volume and it works perfectly!

It does tend to screw up your web logs on the webserver though, traffic will all appear to come from your internal proxy host that's doing the redirection/rewriting.
