Setting general options
The following table describes the general configuration settings in the Intel 
NetStructure Cache 
section.
Option 
Description 
on/off
Enables or disables caching. When you disable 
caching, you shut down all cache and proxy 
services on a node-by-node basis. That is, you 
can turn caching on or off only one node at a time.
You must disable cache services before 
performing certain maintenance tasks.
Intel NetStructure Cache 
Cluster name
Displays the hostname for the appliance. By 
default, the name assumes a standalone node 
and displays the hostname for the appliance as 
the cluster name. If you are configuring an 
appliance to be part of an existing management 
cluster, you must enter the cache cluster name.
Local Domain Expansion 
on/off
Enables or disables local domain expansion. 
If you want the appliance to attempt to resolve 
unqualified hostnames by expanding to the local 
domain, enable expansion. For example, if a user 
makes a request to an unqualified host named 
host_x
, and if the appliance’s local domain is 
y.com
, the appliance will expand the hostname to 
host_x.y.com
.com
 Domain Expansion 
on/off
Enables or disables 
.com
 domain expansion. 
If you want the appliance to attempt to resolve 
unqualified hostnames by redirecting them to the 
expanded address prepended with 
www.
 and 
appended with 
.com
, enable expansion. For 
example, if a user makes a request to 
inktomi
the appliance redirects the request to 
www.inktomi.com
.
If local domain expansion is enabled, the 
appliance attempts local domain expansion 
before 
.com
 domain expansion; the appliance 
tries 
.com
 domain expansion only if local domain 
expansion fails.
