The last decade has seen tremendous growth in usage of the World Wide Web. Web caching is a technology aimed at reducing the transmission of redundant network traffic and improving access to the Web. The key idea in Web caching is to cache frequently- accessed content so that it may be used profitably later. This leads to cost savings, reduction in network traffic, improved access and better content availability. Web Caching and Its Applications gives the reader an understanding of the latest developments in Web caching research. Topics covered include architectural aspects, aspects requiring coordination among caches, aspects related to network traffic, techniques that complement caching, practical aspects, and aspects related to performance. While Web Caching and Its Applications is designed for a professional audience, students will appreciate the exercises for applying the knowledge to solving practical problems related to Web caching and Internet performance. The book includes an exhaustive list of references for further study.
