This document defines a standard mechanism for capturing the history
information associated with a Session Initiation Protocol (SIP)
request.  This capability enables many enhanced services by providing
the information as to how and why a call arrives at a specific
application or user.  This document defines an optional SIP header,
History-Info, for capturing the history information in requests.  SIP
header field parameters are defined to tag the method by which the
target of a request is determined.  In addition, this document
defines a value for the Privacy header specific to the History-Info
header.
