Caching on the Web

Abstract

The World Wide Web provides a means for sharing data and applications among users. However, its performance and in particular providing fast response time is still an issue. Caching is a key technique that addresses some of the performance issues in today’s Web-enabled applications. Deploying dynamic data especially in an emerging class of Web applications, called Web Portals, makes caching even more interesting. In this chapter, we study Web caching techniques with focus on dynamic content. We also discuss the limitations of caching in Web portals and study a solution that addresses these limitations. The solution is based on the collaboration between the portal and its providers.
