Hybrid Prefetching for Improving Page Hit-Ratio

Kushwant Kaur, Dr. Kanwalvir Singh Dhindsa

Abstract: Web prefetching techniques help in improving web page hit-ratio and reducing user perceived latencies by fetching in advance, the most useful web objects into proxy sever cache. This paper explains the integrated prefetching approach that combines Domain top prefetching and Dynamic web prefetching. The data obtained from this approach is based on user access patterns and is stored into the proxy server cache to solve the problem of cache replacement and as a result the hit-ratio is increased.
