Definition of a virtual site
Whereas industry uses the term “virtual host”, Cobalt Networks uses the term
“virtual site”.
In Cobalt’s definition, a virtual site consists of a Domain Name System (DNS)
domain with Web, FTP and email services. Each virtual site contains its own list
of site-user accounts. Each site-user account has its own Web page,
FTP directory, email spool and any number of email aliases. The fully qualified
domain name of a virtual site is unique to that site, while its IP address can be
shared by many sites.
With the advent of name-based virtual hosting, it is no longer necessary to
dedicate an IP address to a virtual site. The Web server can now differentiate
among target virtual sites according to the name requested. Many virtual sites on
the RaQ XTR can share one IP. However, not all services are compatible with
name-based virtual hosting: SSL encryption for Web data, bandwidth
management and an anonymous FTP account can only be enabled on one
name-based virtual site per IP address hosted by the RaQ XTR.
The IP address of the RaQ XTR can be shared by many virtual sites or it can be
unique to one virtual site.
The RaQ XTR has one main site (which cannot be deleted) and virtual sites. The
main site uses the IP address assigned to the RaQ XTR using the LCD console.
On the Server Desktop > Site Management screen, the main site is listed in the
“Virtual Site List” table; the trashcan icon in the third column for the main site is
grayed-out (disabled), as this site cannot be deleted from the list of virtual sites.
The options and features available on a virtual site can also be configured for the
main site.
