Workload Characterization of Uncacheable HTTP Traffic

Proxy caching and content distribution networks (CDNs) are two major approaches to improve Web application performance. Unfortunately, we have witnessed the inefficiency of them to the rapid growth of uncacheable HTTP content, resulting from ever-increasing dynamic Web services, cache busting technologies, and the emergency of various HTTP-based applications. Although several approaches have been proposed for caching fragment-based dynamic Web content, such as edge side include and client-side include, we believe that a general understanding of the characteristics of uncacheable HTTP content is of great importance to the future of HTTP-based content caching and delivery. In this paper, we characterized..
