Title : An Extension to Avoid the Occurance of HERFP

The processing of SIP reqeusts by certain types of proxies can lead
to situations in which multiple non-sucessful responses are
generated, only one of which is ultimately reported to the originator
of the response. In many cases, these non-successful responses
indicate conditions that can be addressed by the requestor, and then
retried; therefore, the elision of them by proxies can lead to a
decrease in the rechability of certain network entites.
This document defines a mechanism that can be employed to avoid the
dropping of such requests with minimal implementation complexity.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
