Title : Suppressing Refer Implicit Subscription
Author(s) : S. Parameswar
Filename : draft-parameswar-sipping-norefersub-00.txt
Pages : 8
Date : 2002-10-30
The recipient of the REFER method [1] creates an implicit
subscription to the 'refer' event. This subscription causes the REFER
recipient to send NOTIFY messages to the sender informing him of the
progress of the REFER. This memo provides for the requirements and
one potential mechanism to suppress the creation of this implicit
subscription, via an option tag - 'norefersub'. This gives the agent
sending the REFER control over the creation of the subscription,
while being backwards compatible with [1].

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.
