4.3.2 Virtual host based on IP address

The IP address-based virtual host appears as multiple hosts to clients by the following three methods:

Using multiple ports
Specifying multiple network interfaces in a single server machine
Specifying an alias of an IP address

Example 1: Open two ports on a Web server on a single server machine, and run as two hosts, one as a Web server that supports SSL and the other as a Web server that does not support SSL.

Example 2: Provide two NIC (Network Interface Card) (IP address: 172.17.40.10 and 172.17.40.20) on a single server machine, and switch hosts according to Web browser requests, on a single Web server.

If the request from Web browser is http://172.17.40.10/, see Application-Server-installation-directory/httpsd/htdocs1/index.html (when DirectoryIndex is specified as index.html).

If the request from Web browser is http://172.17.40.20/, see Application-Server-installation-directory/httpsd/htdocs2/index.html (when DirectoryIndex is specified as index.html).
