From: Internet-Drafts@CNRI.Reston.VA.US Subject: I-D ACTION:draft-mogul-http-caching-00.txt Message-ID: <9602201049.aa20793@IETF.CNRI.Reston.VA.US> Date: Tue, 20 Feb 96 10:49:33 -0500 Mime-Version: 1.0 Content-Type: Multipart/Mixed; Boundary="NextPart" --NextPart A New Internet-Draft is available from the on-line Internet-Drafts directories. 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. Internet-Drafts are available by anonymous FTP. Login with the username "anonymous" and a password of your e-mail address. After logging in, type "cd internet-drafts" and then "get draft-mogul-http-caching-00.txt". A URL for the Internet-Draft is: ftp://ds.internic.net/internet-drafts/draft-mogul-http-caching-00.txt Internet-Drafts directories are located at: o Africa Address: ftp.is.co.za (196.4.160.8) o Europe Address: nic.nordu.net (192.36.148.17) Address: ftp.nis.garr.it (192.12.192.10) o Pacific Rim Address: munnari.oz.au (128.250.1.21) o US East Coast Address: ds.internic.net (198.49.45.10) o US West Coast Address: ftp.isi.edu (128.9.0.32) Internet-Drafts are also available by mail. 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. --NextPart Content-Type: Multipart/Alternative; Boundary="OtherAccess" --OtherAccess Content-Type: Message/External-body; access-type="mail-server"; server="mailserv@ds.internic.net" Content-Type: text/plain Content-ID: <19960219134128.I-D@CNRI.Reston.VA.US> ENCODING mime FILE /internet-drafts/draft-mogul-http-caching-00.txt --OtherAccess Content-Type: Message/External-body; name="draft-mogul-http-caching-00.txt"; site="ds.internic.net"; access-type="anon-ftp"; directory="internet-drafts" Content-Type: text/plain Content-ID: <19960219134128.I-D@CNRI.Reston.VA.US> --OtherAccess-- --NextPart--
