Introduction

 

The appliance can be configured as a web server to accelerate slower 
traditional web servers. Documents stored in cache are served at high speed, 
while documents not in cache are requested on demand from slower, 
traditional web servers. This 

 

 feature is also called 

 

.

 

The appliance can participate in flexible cache hierarchies, where Internet 
requests not fulfilled in one cache can be routed to other regional caches, 
taking advantage of the of nearby caches.

 

The appliance supports the standard Internet Cache Protocol (ICP) to 
interoperate with existing ICP cache hierarchies. The appliance can send ICP 
queries to neighboring caches as part of an ICP cache hierarchy.

 

The appliance caches and serves NNTP news articles and can accept news 
feeds for designated news groups.

The appliance scales from a single node into multiple-node 

 

, allowing 

you to improve system performance and reliability simply by adding more 
nodes to your cluster. Support exists for two types of clusters: 

 

 

and 

 

. For more information on clustering, see

The appliance features both a primary and secondary boot image on separate 
hard drives. When a drive with a boot image fails, a system administrator can 
detect and replace the faulty hard drive. This feature helps maximize the time 
your system is up and running uninterrupted.
