VirtualHost Examples: Running different sites on different ports.

This document attempts to answer the commonly-asked questions about setting up virtual hosts.

These scenarios are those involving multiple web sites running on a single server, via name-based or IP-based virtual hosts.

You have multiple domains going to the same IP and also want to serve multiple ports. By defining the ports in the "NameVirtualHost" tag, you can allow this to work. If you try using <VirtualHost name:port> without the NameVirtualHost name:port or you try to use the Listen directive, your configuration will not work.
