Abstract:
The Hypertext Transfer Protocol (HTTP) is an application-level
protocol for distributed, collaborative, hypertext information
systems. This document defines HTTP/1.1 conditional requests,
including metadata header fields for indicating state changes,
request header fields for making preconditions on such state, and
rules for constructing the responses to a conditional request when
one or more preconditions evaluate to false.
