The Px series application switch uses a single VIP, located at 192.1.1.1:80, to service all three domains.

When the client request arrives, the application switch examines the request to determine the domain name being requested. In Figure 7-2, the domain name requested is www.speakyourmind.net.

Using domain name switching, the application switch matches the domain name to server group 2. The application switch then uses the configuring server load balancing policy (round robin, weighted round robin, least connections, or weighted least connections) to select a particular server within the server group. The request is then forwarded to the selected server in server group 2.

The following configuration shows the commands used to configure the combination of the three websites. Another server group, mainpage, contains a page that allows the user to self-select, just in case the domain specified by the user does not match either of the three. This could happen, for example, if the actual IP address is used instead of a host name.

config service vip 10.65.31.202 port 8080 proto tcp l7 class http
