Am I correct in assuming that you are advocating this feature because IBM believes that it is useful and plans to support it in
I had previously thought that you proposed the feature because you thought some unknown vendor might want the feature.
One downside of this feature is that it requires the printer to be configured to know about some notification server and it requires
an IPP notification server which may or may not be a printer. All this adds up to a more complex solution to deploy and to administer.

While I respect Bob's, Ira's, Ted's (and other's) opinions the conversation sure seems to have adopted an arbitrary tone w.r.t. to IPP bells, whistles and trinkets. If someone says they can use a simple feature like redirect I see no need to block it. If it were mind bending I would argue otherwise... but redirect is quite simple by any gauge and doesn't even register on the scale of numbness many feel when first confronting IPP.
Notification redirect should consist of writing the client to accept a URL (in place of the printer URL) where it should expect to find subsequent notifications.
I can always feature the redirect... so I guess I'm going down for last count w/o a big struggle. I don't think Bob is correct in attributing lack of chatter as lack of significance. I think the spotlight is off IPP and you are witnessing the polling interval.

Harry says that redirect is simple to implement. I agree, but implementation
is only part of the issue.
Each feature requires documentation, testing and support. There is no such
thing as a free feature.
Very few people have responded to this issue and no one has said that it is
a necessary feature.
So, it would seem hard to justify keeping a feature that.seems to have no
value to anyone, but does have a cost to every vendor.
