I still like the idea of 3 URLs for the following reasons
1. The data URL (as I understand it) can point directly to a "virtual
printer" with specific PDL, and/or configuration. I think this
could be powerful in directing jobs to the appropriate device or
instance of a device.
2. The status URL is basically a guaranteed unique printer assigned
job ID to be used to monitoring job progress, state etc. If we
didn't return this as a URL, we'd need some other means of
accomplishing this in the protocol and I doubt we could do much
better than a URL. I was only pointing out, with my earlier msg,
that just returning this status URL to the submitter does not
facilitate administrative actions by separate, standalone
3. I believe the main benefit of the Modify URL is that it can be
subject to higher scrutiny in terms of authentication. Otherwise,
I'd say Status and Modify could be the same URL - both pointing
to a specific job. So I see Modify URL as the status URL with a
password, if you will. I do not see the need for separate URLs for
each modify operation (hold, cancel, move etc.). But, then, I'm
not tuned in to all the subtle nuances of who gets to manage what
in a DPA environment, so, if you need multi levels of authentication,
you might want multiple modify URLs.
