Virtual Hosting Configuration Overview
The sequence of events for configuring virtual hosting based on HTTP Host: headers is
described below:
1. The network administrator defines a domain name as part of the 128 supported URL
strings.
Both domain names “www.company-a.com” and “www.company-b.com” resolve to the same
IP address. In this example, the IP address is for a virtual server on the switch.
2. “www.company-a.com” and “www.company-b.com” are defined as URL strings.
3. Server Group 1 is configured with Servers 1 through 8.
Servers 1 through 4 belong to “www.company-a.com” and Servers 5 through 8 belong to
“www.company-b.com.”
4. The network administrator assigns string “www.company-a.com” to Servers 1 through 4
and string “www.company-b.com” to Servers 5 through 8.
5. The Web switch inspects the HTTP host header in requests received from the client.
n If the host header is “www.company-a.com,” the switch directs requests to one of the
Servers 1 through 4.
n If the host header is “www.company-b.com,” the switch directs requests to one of the
Servers 5 through 8.
