I'd like to propose the following addition to the proposed WEBREPL/WREC
charter, for our hopeful discussion tomorrow:
The additions are in parentheses.

******************
The World Wide Web (WWW) employs the HTTP protocol (RFC 2068) between the
client and server. HTTP makes allowances with respect to intermediate
infrastructure which may exist between the client and servers, such as
caching proxies, gateway proxies, and other "servers". Though highly
desirable and possible in a few implementations, interaction between
clients and these intermediaries is rarely automatic or optimal and often
manually configured. There is currently no open, supported protocol for client
configuration.
In many cases, these intermediaries are configured to communicate with
other intermediaries, (so-called Inter-Cache Communication) and there exist
many different protocols and standards, both proprietary and open, for
communication between these intermediaries.
(Both client-cache and cache-cache communications can be further faciliated
by communication
between caches and network devices. There are several proprietary as well
as open
approaches for this communication under development.)
The aim of this working group is to review and document current practice
with regards inter-cache communication, client-cache communication, (and
cache-nework element communication) and define a framework for a future
development of both within the IETF framework. The scope of this working
group
is deliberately limited to cache-type intermediaries.
