To set up virtual server

1. Create a listen socket

2. Create a class of virtual servers

3. Configure the services for the class

4. Create the virtual servers in a virtual server class

5. Configure virtual servers

   Please note that you must enter an existing virtual server in the default virtual server field when you create a listen socket. You can use the virtual server created when you installed the server, and then go back and change it after you’ve created additional virtual servers.
