HTTP Usage in the Registration Data Access Protocol (RDAP)
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.
