Setting HTTP parent caching options
The appliance can participate as a member of an HTTP cache hierarchy. You can 
point your appliance at a parent network cache—either another Intel NetStructure 
Cache Appliance or a different caching product—to form a cache hierarchy, 
wherein a child cache relies upon a parent cache in fulfilling user requests.
    parent
failover
You can specify more than one parent cache to be queried. If the first parent 
cache does not respond to the request, the appliance tries the next parent cache. 
The appliance supports multiple parent caches and parent failover. Use the 
command-line interface to configure multiple parent caches and parent failover 
(which gives appliance a sequence of parent caches to query if the first parent 
cache misses). See
The following table describes the options.
Option 
Description 
Parent Caching 
on/off
Enables or disables parent caching. To set parent caching 
on, you must also name a parent cache.
Parent Cache
Identifies the parent cache and port. Using the following 
format: 
parent_name:port_number
. The port must be 
dedicated. If the appliance cannot find a requested object in 
its own cache, it searches the parent cache before 
searching the Internet. If you want parent failover, you can 
specify more than one parent cache; for example, 
parent1:port1; parent2:port2
