ABSTRACT Web prefetching is an important aspect to find the possibility of finding which object would be requested in near future. Demand of internet and easy accessibility of information communication and flexibility had put gigantic pressures on the principal infrastructure of WWW. The World Wide Web is an immensely scattered and provides access to shared data with ease. Due to this there is a huge pressure on server with respect to information load resulting in the compromise of service at the end user. Further the load imbalances between the servers that arise from the severe nature of irregular web access essentially reflecting the underlying predictable and often unpredictable human nature is a concern from the resource deployment point of view. Besides the media type adds further limitations to the whole process. But the cache management has many challenges in balancing the process of meeting the demands of the users on the one hand and ensuring optimal utilization of system resources on the other hand. Caching and pre-fetching is middle-aged technology widely used in many areas such as Database Systems and Operating Systems.
