Why use this caching appliance?
Caching can significantly reduce pressure on busy networks and servers by
storing copies of popular documents near their users. Instead of making multiple
requests for the same document across congested networks to overloaded servers,
users access copies from the caching appliance’s large, fast local cache. This
reduces backbone congestion, provides faster response, and improves the quality
of service.

Web proxy cache
User requests go to the appliance on the way to the destined web server. If the
cache contains the requested document, the appliance serves the requested
document directly. If the cache does not have the desired document, the
appliance acts as a proxy, fetching the document from the web server on the
user’s behalf, and keeps a copy to satisfy future requests.
