“…Challenger et al [12] analyzed object size distributions based on server traces from the 2000 Olympics site. Although related to our objectives, their work employs a different definition of what an object is: they include not only the individual objects embedded within a document, but also the entire generated document itself.…”

“…Such work, which has focused on both server-side [11,12,16,42] and cache-side [10,18,27,29,38] has typically been validated with specific, proprietary workloads. For example, Challenger et al used the 1998 Olympic winter games workload in [11], and the 2000 Olympic games workload in [12], and Douglis et al used a modified internal AT&T Webbased "recruiting database" to evaluate their idea of HPP [18]. The work in this paper addresses this shortcoming, providing both models and tools that allow researchers to efficiently evaluate their techniques on a variety of (synthetic) workloads.…”

“…Server-side techniques, exemplified by techniques such as delta encoding [28], data update propagation [11], fragment-based page generation [12,18], and the Cachuma [42] class-based page classification scheme reduce the burden on the server by allowing reuse of previously generated content to serve new requests. Cache-side techniques, exemplified by systems such as Active Cache [10], Gemini [29], CONCA [34], and the content assembly technique proposed by Wills et al [38], attempt to reduce the latency of dynamic content delivery by moving some functionality to the edge of the network.…”

“…One method which can reduce the overhead for generating dynamic pages and enable caching of some parts of personalized pages is to define these pages as being composed of multiple fragments [15]. In this approach, a complex Web page is constructed from several simpler fragments.…”

This paper provides an overview of techniques for improving Web performance. For improving server performance, multiple Web servers can be used in combination with efficient load balancing techniques. We also discuss how the choice of server architecture affects performance. We examine content distribution networks (CDN's) and the routing techniques that they use. While Web performance can be improved using caching, a key problem with caching is consistency. We present different techniques for achieving varying forms of cache consistency.

Abstract. The recent trend in the Internet traffic is increasing in requests for dynamic and personalized content. To efficiently serve this trend, several serverside and cache-side fragment-based techniques, which exploit reuse of Web pages at the sub-document level, have been proposed. Most of these techniques do not focus on the creation of the fragmented content from existing dynamic content. Also, existing caching techniques do not support fragment movement across the document, a common behavior in dynamic content. This paper presents two proposals that we have suggested to solve these problems. The first, DyCA, a dynamic content adapter, takes original dynamic Web content and converts it to fragment-enabled content. Thus the dynamic parts of the document are separated into separate fragments from the static template of the document. This is dependent on our proposed keyword-based fragment detection approach that uses predefined keywords to find these fragments and to split them out of the core document. Our second proposal, an augmentation to the ESI standard, allows splitting the information of the position of each fragment in the template from the template data itself by using a mapping table. Using this, a fragment enabled cache can have a more fine grained level of identifying fragments independent of their location on the template, which enables it to take into account fragment behaviors such as fragment movement. We used the content taken from three real Web sites to achieve a detailed performance evaluation of our proposals. Our results show that our keyword-based approach for fragment extraction provides us with cacheable fragments that, when combined with our proposed mapping table augmentation, can provide significant advantages for fragment-based Web caching of existing dynamic content.
