A Virtual Farm includes the WebMux and the servers under it. Functionally, it acts as a
single unit on a network. For example, http://www.you.com is one virtual server farm;
https://www.me.com is another farm, and ftp://ftp.cainetworks.com is the third farm. The first
farm works on a set of servers on port 80, the second farm consists of another set of servers
on port 443, and the third farm works on a set of servers on port 21. The WebMux supports
combining 80/443 ports as one single farm, so that same client browsing the site in HTTP
mode will be sent to the same server for HTTPS requests. In the combined configuration, you
must select HTTP/S as the farm service. Ports 80/443 will then be combined into one farm.
To serve the Internet, there must be at least one Internet Router. The local area network that
connects the router and the WebMux is called the Router LAN. In this LAN, the WebMux
