The main goal of this research is to design a hybrid proxy caching replacement scheme by considering the performance metrics (Hit Rate and Byte Hit Rate) to improve the performance of web caching.
To accomplish the above stated general objective, the following specific objectives are developed:-
• To think about and examine existing web caching algorithms
• To investigate the possibility of identifying a policy that optimizes both metrics at the same time, or that at least allows easy control over which performance metric it optimizes.
• To develop a trace driven simulation to compare the performance of the caching Algorithms and evaluate the adaptive model.
