Certain investigations on reducing web access latency by combining intelligent web caching techniques with pre fetching

Abstract

The exponential growth in the usage of World Wide Web WWW for data dissemination has led to enormous web traffic and hence web users experience considerable access delays To reduce the access delay it is better to keep the frequently used information by various web users in the cache memory because this helps the users to retrieve the information immediately Apart from experiencing less access delay caching process also helps in better bandwidth utilization reduction of network congestion and load reduction on the origin server As web proxy cache size is limited cache replacement methods are required to handle the cache content The performance of web caching methods is analyzed using the widely used metrics Hit Ratio HR and Byte Hit Ratio BHR HR is the percentage of the number of requests that is entirely served by the cache over the total number of requests newline
