Abstract (2. Language):
The increasing demand for World Wide Web
(WWW) services has made document caching a necessity to
decrease download times and reduce Internet traffic. To make
effective use of caching, an informative decision has to be
made as to which documents are to be evicted from the cache
in case of cache saturation. This is particularly important in a
wireless network, where the size of the client cache at the
mobile terminal (MT) is small. Several types of caching are
used over the Internet, including client caching, server caching,
and more recently, proxy caching. In this article we review
some of the well known proxy-caching policies for the Web.
We describe these policies, show how they operate, and
discuss the main traffic properties they incorporate in their
design. We argue that a good caching policy adapts itself to
changes in Web workload characteristics. We make a
qualitative comparison between these policies after classifying
them according to the traffic properties they consider in their
designs.
