From the Server Manager, click the Virtual Server Class tab.
Click Add Class.
Name the class.
Insert a document root for the class.
The directory must already exist. All virtual servers for this class will have document roots in this absolute path, unless you specify otherwise. If you use /$id as the last part of the path, a document root folder named for the virtual server ID is automatically created within the class’ document root path.
Once you have created a class of virtual servers, choose the services associated with the class. For more information, see Chapter 17, Content Management.
