1 Utilizing Virtual Private Networks with ISA Server 2006.
Using Web Caching to Improve and Control Web Browsing
The ???acceleration??? portion of the Internet Security and Acceleration product refers to ISA
Server??™s capability to act as a proxy for network clients, caching commonly used web sites
and their associated graphics, text, and media, and serving them up to end users more
quickly than if they had to access the content across the Internet. An additional benefit to
this approach is the fact that all outbound web and FTP traffic is then scanned by ISA for
threats, exploits, and restricted content. ISA has long been a product of choice for those
seeking web-caching capabilities. In fact, the previous iteration of the product, Microsoft
Proxy Server, was primarily used for that capability by itself in many organizations. ISA
Server 2006 caching builds upon this success by further improving the system??™s caching
capabilities.
Utilizing the caching capabilities of ISA Server 2006 is a straightforward and easy-todeploy
method of getting more bandwidth out of an Internet connection. In addition to
the capability to cache requests made to web and FTP sites, ISA Server also provides for the
capacity to provide commonly used content from web sites for caching by downloading it
on a regular basis.
