WebDelegator is a server solution that permits a collection of web servers to be hosted on a single IP address. The software accepts connections on a particular address, and establishes connections to the appropriate web server to fulfill requests.

Features: WebDelegator is a server solution that permits a collection of web servers to be hosted on a single IP address This is accomplished by binding to the HTTP service port on the single IP address, just like an ordinary web server. However, when a connection arrives, the request is handled by creating another connection to a specific web server from a group of servers. The domain name specified in the request header field determines to which web server the request should be routed to. This way one can associate several web servers to a specific IPv4 address which is scarce now-a-days. To the web server receiving the service requests it would appear as if all the requests are coming from the WebDelegator. Overall then, the software accepts connections on a particular address, and establishes connections to the appropriate web server to fulfill the requests. The HTTP request header is used to determine the destination web server, and to preserve the IP address of the originator.

To resolve this situation, the IP address of the originator is appended to the referrer header field of the forwarded requests. This way, there is no information loss at all. The application has an administrative interface to manage the activity. It allows a web browser to be used to configure web server mappings. It also controls which clients can connect. You can monitor the internal workings by looking at the connection and data transfer related statistics and an activity log. The admin web interface can get integrated with the Internet Information services so that security features of that could be utilized.

Overall: Typically you would go to a hosting service provider and not worry about such issues. But if you do try to host more than one web server, this is a simple and nice solution.
