A New Internet-Draft is available from the on-line Internet-Drafts 

       Title     : A design for caching in HTTP 1.1 Preliminary Draft      
       Author(s) : J. Mogul
       Filename  : draft-mogul-http-caching-00.txt
       Pages     : 36
       Date      : 02/19/1996

I propose a caching design for HTTP 1.1, including the definition of terms,
the description of a model, the specification of related HTTP headers, and 
the algorithms to be used.     

The proposed design uses opaque cache validators and explicit expiration 
values to allow the server to control the tradeoff between cache 
performance and staleness of the data presented to users.  The server 
may choose to ensure that a user never unwittingly sees stale data, 
or to minimize network traffic, or to compromise between these two 
extremes.  The proposed design also allows the server to control whether 
a client sees stale data after another client performs an update.  

This draft is not intended to become a standards-track document.  
The ultimate output of the HTTP subgroup will be a set of changes 
to the HTTP/1.1 draft specification [1].  In the interests of 
making rapid forward progress and in capturing some of the motivation 
and rationale of our design(s), it seems useful to produce 
an Internet-draft document in the interim.  Note that this draft 
in its entirety does not currently represent the consensus 
of the subgroup, although several sections do represent an 
apparent consensus.

Send a message to:  mailserv@ds.internic.net. In the body type: 
     "FILE /internet-drafts/draft-mogul-http-caching-00.txt".
NOTE: The mail server at ds.internic.net can return the document in
      MIME-encoded form by using the "mpack" utility.  To use this
      feature, insert the command "ENCODING mime" before the "FILE"
      command.  To decode the response(s), you will need "munpack" or
      a MIME-compliant mail reader.  Different MIME-compliant mail readers
      exhibit different behavior, especially when dealing with
      "multipart" MIME messages (i.e., documents which have been split
      up into multiple messages), so check your local documentation on
      how to manipulate these messages.
For questions, please mail to Internet-Drafts@cnri.reston.va.us.

Below is the data which will enable a MIME compliant mail reader 
implementation to automatically retrieve the ASCII version
of the Internet-Draft.
