This chapter outlines the Webcache support feature, explains the key
benefits of using this feature, and gives examples of how and why you
would use it in your network.
To make Webcache support available on the SuperStack 3 Switch
4400 SE, upgrade the product to the Switch 4400 SE Enhanced Software
Upgrade (3C17207).
For detailed descriptions of the Web interface operations and the
Command Line Interface (CLI) commands that you require to manage the
Switch please refer to the Management Interface Reference Guide
supplied in HTML format on the CD-ROM that accompanies your Switch.
What is Webcache
Support?
Webcache support is a feature that allows local storage (caching) of
frequently accessed web pages on a Webcache attached to your
network. This means your network users can access these locally stored
web pages without going over a WAN connection.
The Webcache periodically checks live web pages to find out if the
current cached pages are out-of-date and replaces them accordingly.
Benefits of Webcache
Support
The primary benefit of the Webcache support feature is to increase the
performance of the local network by redirecting HTTP (web) traffic to a
local Webcache. An increase in network performance is achieved
because:
■
traffic on a WAN connection is reduced as the local cache, rather than
remote web servers can serve requests from multiple users that are
accessing the same web content.
