Web Replication and Caching (wrec) Charter Status: Concluded March, 2001 Chair(s): Bill Maggs John Martin Description of Working Group: The purpose of this working group is to define a co-ordinated caching and replication framework for the world wide web. Replication of web services and caching of http responses are distinct paradigms that to a large degree require distinct solutions. However, it is also important that web caches and replicated services be able to coexist. Ultimately, the working group will define a framework for efficient, reliable, and predictable service in a web which includes both replicas and caches. Part of this framework will be a means by which replicas and caches may be automatically discovered and utilized by clients. Because of the wide variety of caching and replication solutions which are already in use, the initial task of the group is to familiarize itself with the diversity of existing practice. The group will therefore produce a document which provides a taxonomy of existing caching / replication developments and terminology which would be used as a reference for later work. In parallel with this, existing protocols and standards which are not publicly documented will be submitted to the IESG for publication as informational RFCs by their respective proponents. Once the initial phase is complete, the group will make a recommendation as to whether further protocol work is necessary or desirable, and submit a revised charter for consideration by IESG and IAB.
