What is the
Webcache?
The SuperStack ® 3 Webcache 1000 and 3000 are high-performance,
easily configurable webcache appliances. They offer the following
benefits to your network:
■
Reduced Network Traffic
The Webcache locally stores frequently accessed Web content and
quickly serves it to the end user on demand. This reduces the amount
of traffic on the WAN, providing significant cost benefits by reducing
the bandwidth requirement on expensive WAN links.
■
Reduced Web Latency
The end user receives Web content more quickly and with greater
quality of service if it is served from a local, high-speed Webcache
than if it is served from the Internet. Web object requests that have to
travel over long distances are limited to the speed and capacity of the
slowest link in the path. A Webcache that is closer to the client
machines reduces the potential for slow links and dropped data
packets.
