A Novel Approach For Web Pre-fetching and caching Varun Kumar

Abstract- Due to the fast development of internet services and a huge amount of network traffic web caching and prefetching are the most popular techniques that play a key role in improving the Web performance by keeping web url that are likely to be visited in the near future closer to the client. Web caching technique work integrated or independently with the web prefetching. The Web caching and prefetching techniques are complement each other since the web caching exploits the temporal locality for predicting revisiting requested url, while the web prefetching utilizes the spatial locality for predicting next related web object of the requested Web url. In this paper proposed work represent the working of a novel approach for web caching and prefetching.This technique enhance the performance with help of using user priority approach. In this paper explain how the response time of hit taken from the user cache is less as compare to the data taken directly from the log file.In this approach cache size and which replacement policy is used for replacement in cache play an important role.For this in this paper explain the comparision of three replacement technique – LRU,FIFO,LFU on basis of hit rate on cache.For improving the performance and response time in web caching and prefetching technique use the best replacement policy after comparision.In this paper also explain enhance the performance of caching and prefetching using user based approach and analyze the prefetching hit ratio b/w priority and user based approach in which clustering used
