Description of Working Group:

Note: This working group is jointly chartered by the Applications Area
     and the Transport Services Area.

The HTTP Working Group will work on the specification of the Hypertext
Transfer Protocol (HTTP). HTTP is a data access protocol currently run
over TCP and is the basis of the World-Wide Web. The initial work will
be to document existing practice and short-term extensions. Subsequent
work will be to extend and revise the protocol. Directions which have
already been mentioned include:

o improved efficiency,
o extended operations,
o extended negotiation,
o richer metainformation, and
o ties with security protocols.

Note: the HTTP working group will not address HTTP security extensions
as these are expected to be the topic of another working group.

Background information

The initial specification of the HTTP protocol was kept in hypertext
form and a snapshot circulated as an Internet draft between 11/93 and
5/94. A revision of the specification by Berners-Lee, Fielding and
Frystyk Nielsen has been circulated as an Internet draft between 11/94
and 5/95. An overview of the state of the specifications and a
repository of pointers to HTTP resources may be found at

 http://www.w3.org/hypertext/WWW/Protocols/Overview.html

Once established, the working group will expand and complete that
document to reflect HTTP/1.0 as it has been implemented by World-Wide
Web clients and servers prior to November 1994. The resulting
specification of HTTP/1.0 will be published for review as an
Internet-Draft and, if deemed appropriate, will be submitted to the
IESG for consideration as a Proposed Standard or Informational RFC.

In parallel with the above effort, the working group will consider
enhancements/restrictions to the current practice in order to form a
specification of the HTTP protocol suitable for eventual consideration
as a proposed standard.

Also in parallel with the above efforts, the working group will engage
in defining (or selecting from various definitions) a next-generation
protocol for hypertext transfer (HTTPng).

A description of HTTP/1.0 as it is generally practiced currently on the
Internet has been submitted to become an Informational RFC. The working
group is considering enhancements/restrictions to the current practice
in order to form a specification of the HTTP protocol suitable for
eventual consideration as a proposed standard.

Goals and Milestones:

  Done         Review draft charter for discussion at the Chicago WWWF'94
               conference. Invest an interim Chair for the working group.
               Determine writing assignments for first draft of HTTP/1.0
               document.

  Done         Draft working group charter. Establish mailing list and
               archive.

  Done         Meet at the San Jose IETF as a BOF. Review HTTP/1.0
               Internet-Draft and decide whether it should be published as
               Informational, should be a candidate for further working
               group development, or should be allowed to expire.
               Determine writing assignments for first drafts of the
               HTTP/1.1 or HTTPng documents. Establish charter and submit
               to IESG

  Done         Publish an Internet-Draft on HTTP as reflected by current
               practice (HTTP/1.0)

  Done         Revise the Internet-Draft on HTTP/1.0 and, if desired,
               submit to the IESG for consideration under the category
               determined at San Jose IETF.

  Done         Final review of HTTP/1.1 draft at the Danvers IETF. Revise
               HTTP/1.1 draft and submit to IESG for consideration as
               Proposed Standard. Review progress on HTTPng.

  Done         Final review of HTTPng draft at the Dallas IETF. Revise
               HTTPng draft and submit to IESG for consideration as
               Proposed Standard. Retrospective look at the activities of
               the HTTP WG.

  Done         Initial publication of HTTP/1.1 proposal from document
               editors.

  Done         Publish Internet-Drafts on HTTP/1.0

  Done         Complete review of HTTP/1.1 proposal and pending I-Ds by
               subgroups: Persistent connections; cache-control and proxy
               behavior; content negotiation; authentication;state
               management;range retrievals; extension mechanisms; other
               new methods and header features.

  Done         Submit HTTP/1.1 as Internet-Draft (editing team led by Jim
               Gettys).

  Done         Submit HTTP/1.1 to IESG for consideration as a Proposed
               Standard.

  Done         Review additional features for HTTP/1.1

  Done         Submit HTTP/1.2 to IESG for consideration as a Proposed
               Standard.


Internet-Drafts:

 No Current Internet-Drafts.
