    abstract =  {The Session Initiation Protocol (SIP) is increasingly being used in systems that are tightly coupled with Hypertext Transport Protocol (HTTP) servers for a variety of reasons. In many of these cases, applications can benefit from being able to discover, in near real- time, when a specific HTTP resource is created, changed, or deleted. This document proposes a mechanism, based on the SIP Event Framework, for doing so. {[}STANDARDS-TRACK{]}},
