    abstract =  {The Hypertext Transfer Protocol (HTTP) is an application-level protocol for distributed, collaborative, hypermedia information systems. HTTP has been in use by the World Wide Web global information initiative since 1990. This document is Part 4 of the eight-part specification that defines the protocol referred to as "HTTP/1.1" and, taken together, updates RFC 2616 and RFC 2617. Part 4 defines request header fields for indicating conditional requests and the rules for constructing responses to those requests.},
