Abstract
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.
