After too many months and too many drafts, those of us who have been working on a proposed specification for Delta Encoding in HTTP seem to have reached a consensus on the basic design: Title : Delta encoding in HTTP Author(s) : J. Mogul, B. Krishnamurthy, F. Douglis, A. Feldmann, Y. Goland Filename : draft-mogul-http-delta-06.txt Pages : 46 Date : 25-Aug-00 Many HTTP requests cause the retrieval of slightly modified instances of resources for which the client already has a cache entry. Research has shown that such modifying updates are frequent, and that the modifications are typically much smaller than the actual entity. In such cases, HTTP would make more efficient use of network bandwidth if it could transfer a minimal description of the changes, rather than the entire new instance of the resource. This is called 'delta encoding.' This document describes how delta encoding can be supported as a compatible extension to HTTP/1.1. A URL for this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-mogul-http-delta-06.txt Although this draft is NOT a product of the HTTP WG, we would like to give the WG the traditional two-week Last Call period for comments before we ask the IESG to approve this draft as a Proposed Standard. NOTE: we have removed from this document any support for "Clustering" and "Templates", which are now optional features described in a separate draft: http://www.ietf.org/internet-drafts/draft-mogul-http-dcluster-00.txt This draft is NOT ready for submission to the IESG, and these features are NOT up for discussion as part of this "Last Call." -Jeff
