           Hypertext Transfer Protocol (HTTP): Range Requests
                  draft-fielding-httpbis-http-range-00

Abstract

   The Hypertext Transfer Protocol (HTTP) is a stateless application-
   level protocol for distributed, collaborative, hypertext information
   systems.  This document defines range requests and the rules for
   constructing and combining responses to those requests.

   This document obsoletes RFC 7233.

Editorial Note

   This note is to be removed before publishing as an RFC.

   _This is a temporary document for the purpose of planning the
   revisions of RFCs 7230 to 7235.  This is not yet an official work
   item of the HTTP Working Group._

   Discussion of this draft takes place on the HTTP working group
   mailing list (ietf-http-wg@w3.org), which is archived at
   <http://lists.w3.org/Archives/Public/ietf-http-wg/>.

   Errata for RFC 7233 have been collected at <https://www.rfc-
   editor.org/errata_search.php?rfc=7233>, and an additional issues list
   lives at <https://github.com/httpwg/http11bis/issues>.

   The changes in this draft are summarized in Appendix E.1.
