With the unprecedented growth of Internet and World Wide Web over the past few years, web sites become increasingly complex. Due to this complexity, performance and scalability are the major issues for web sites/content providers. Again with the rapid growth of e commerce business, web sites are increasingly relying on dynamic content generation applications to provide dynamic interaction and personalized experiences to the web sites users. However, to generate the web page with dynamic contents for each user request requires computation as well as communication cost across multiple tier/components. So, the dynamically page generation time increases due to database-driven e commerce application, frequently update contents, personalization and different access device. We have proposed an approach that integrates the page fragment cache (PFC) with database cache (DBC). We have also introduced a global cache manager (GCM) in our proposed system that helps the DB server to reduce the overhead. The main goal of this paper is to improve the performance and scalability for generating the dynamic web page. Here the use of PFC cache in the separate engine (not in the application server) and also the use of middle-tier cache together with GCM significantly reduce the response time latency for the generation of dynamic web sites.
