Abstract: In this thesis, our main objective is to assist forward proxies to provide better content reusability and caching, as well as to enable reverse proxies to perform content delivery optimization. In both cases, it is hoped that the latency of web object retrieval can be improved through better reuse of content and the demand for network bandwidth can be reduced. We achieve this objective through a deeper understanding of the attributes for delivery. We analyze how objectsa?? content settings affect the effectiveness of their cacheability from the perspectives of both the caching proxy and the origin server. We also propose a solution, called the TTL (Time-to-Live) Adaptation, to help origin servers to enhance the correctness of their content settings through the effective prediction of objectsa?? TTL periods with respect to time. From the performance evaluation of our TTL adaptation, we show that our solution can effectively improve objectsa?? cacheability, thus resulting in more efficient content delivery.
