An adaptive prefetching method for web caches

Abstract

This paper presents a new approach to predict web documents by tracking search patterns of users and by managing documents depending upon the number of hits. Several hot spot documents and their linked documents are stored in cache servers and transmitted them to clients for fast response. The adaptive prefetching method, using search patterns of users, analyzes documents along with the navigation patterns and marks several popular documents. If one of these marked documents is hit, all marked documents are loaded into the cache but only the requested document is transmitted to clients. Cache servers can save their cache memory space as well as provide fast response to clients. The results show that the average response time of the proposed method decreases to 20% compared with other methods and the cache hit rate is increased to 18% of other methods. © Springer-Verlag Berlin Heidelberg 2004.
