Hi Tom,

First - I agree that it would still be good to drop redirect from IPPGET
and design it IN GENERAL for IPP (any operation response could return
the redirect), including the fact that while it's nice for interoperability
IPP Clients do NOT need to honor and follow redirects (any more than
HTTP Clients need to do so - it's a matter of client policy).

Second - if we publish IPPGET as a Proposed Std RFC (as you suggest)
and LATER add redirect, we MUST recycle at Proposed Std RFC - it's
illegal to add ANY new features when moving from Proposed Std to
Draft Std status - only dropping existing features is legal.

Cheers,

Subject: IFX> Attempt to close on the two Notification specs at the face
to fac e meetings


The IPP WG Last Call period closed July 31 on the two IPP Notification specs
that are required for IPP Notification:

(1) IPP Event Notifications and Subscriptions
<draft-ietf-ipp-not-spec-09.txt>
(2) The 'ippget' Delivery Method for Event Notifications
<draft-ietf-ipp-notify-get-07.txt>

and Carl-Uno declared that (1) was approved, since there were no comments
and that (2) achieved consensus to drop the redirection mechanism entirely
from the IPPGET document.

However, we have continued discussion about the merits and problems of the
redirection mechanism because Harry Lewis has been the main objector to
removing the redirection mechanism from IPPGET.  As a result I have not yet
produced a new version of the document and Carl-Uno has not forwarded either
of the documents to Ned Freed, our Area Director.

Process considerations:

Could we delete the redirection mechanism for now from IPPGET?  Get our RFC
published as a Proposed standard.  Implement IPPGET and do interoperability
testing.  See if the burden in the Printer of supporting the IPPGET method
justifies offloading it to a Notification Server using the redirect
mechanism.  If the implementation experience shows that its not much of a
burden in the Printer we made the right decision to delete redirection.  If
implementation experience shows that having a Notification Server is
important to off-load the Printer's support of the IPPGET method, then add
the redirection back into the IPPGET spec before progressing the document to
a Draft standard.  Perhaps in the meantime, IBM can also implement the
Notification Server and see if it is really a win and that the extra
administrative effort is worth the benefit to simplifying the Printer
implementation.

Comments?

Tom
