Future access to web-based content is likely to be dominated by two trends: (a) increasing amounts of dynamic, personalized content, and (b) a significant growth in “on-the-move” access using various mobile resource-constrained devices. These trends point to a situation where a user would have ubiquitous access to content, but require that content be efficiently delivered to the user irrespective of location, and in a form most suited to the user’s end device. Unfortunately, classical caching and transcoding solutions do not work well together, necessitating a new caching architecture built from the ground-up to handle problems caused by dynamic content, transcoded versions of objects, and the nomadic nature of users. This paper describes the goals and architecture of such a system: CONCA, an architecture for Consistent Nomadic Content Access.

Proxy caching is an effective technique to reduce the network resources consumed by web services as well as the access latencies perceived by web users. This article discusses the issues and challenges of deploying web caching proxies over the Internet. We focus on the cache management for conventional web objects such as HTML pages and images and present the state-of-the-art solutions to various cache management problems including prefetching, consistency maintenance, and cooperative caching. We also highlight several possible research directions with the emerging applications and services.

This memo specifies standard terminology and the taxonomy of web replication and caching infrastructure as deployed today. It introduces standard concepts, and protocols used today within this application domain. Currently deployed solutions employing these technologies are presented to establish a standard taxonomy. Known problems with caching proxies are covered in the document titled "Known HTTP Proxy/Caching Problems", and are not part of this document. This document presents open protocols and points to published material for each protocol.
