       HTTP usage in the Registration Data Access Protocol (RDAP)
                    draft-ietf-weirds-using-http-14

Abstract

   This document is one of a collection that together describes the
   Registration Data Access Protocol (RDAP).  It describes how RDAP is
   transported using the Hypertext Transfer Protocol (HTTP).  RDAP is a
   successor protocol to the very old WHOIS protocol.  The purpose of
   this document is to clarify the use of standard HTTP mechanisms for
   this application.
