Multiple Domains, Multiple Servers, One IP Address
In the following article I describe how to set up multiple websites on seperate physical servers behind one ip. Now you can run IIS and Apache on seperate machines behind one ip address. This article assumes you have basic knowledge of installing and configuring apache.
Problem: Multiple websites hosted on seperate servers behind one ip.
Solution: For reasons requested by our client we used the proxy/gateway ability of Apache to read the http headers and pass to the correct server.
