9 USING WEBCACHE SUPPORTThis chapter outlines the Webcache support feature, explains the keybenefits of using this feature, and gives examples of how and why youwould use it in your network.To make Webcache support available on the SuperStack 3 Switch4400 SE, upgrade the product to the Switch 4400 SE Enhanced SoftwareUpgrade (3C17207).For detailed descriptions of the Web interface operations and theCommand Line Interface (CLI) commands that you require to manage theSwitch please refer to the Management Interface Reference Guidesupplied in HTML format on the CD-ROM that accompanies your Switch.What is WebcacheSupport?Webcache support is a feature that allows local storage (caching) offrequently accessed web pages on a Webcache attached to yournetwork. This means your network users can access these locally storedweb pages without going over a WAN connection.The Webcache periodically checks live web pages to find out if thecurrent cached pages are out-of-date and replaces them accordingly.Benefits of WebcacheSupportThe primary benefit of the Webcache support feature is to increase theperformance of the local network by redirecting HTTP (web) traffic to alocal Webcache. An increase in network performance is achievedbecause: traffic on a WAN connection is reduced as the local cache, rather thanremote web servers can serve requests from multiple users that areaccessing the same web content.
