POST for start-job
POST print job data
POST end-job
for the start-job POST, I would like to see the IPP server return
preformatted URLs for subsequent operations to this particular
server job, such as status requests, cancel request, etc.
The IPP "standard" part of this specification would only specify
the order that these URLs are transmitted by the server, but not
the format of the individual URL components.
i.e.,
POST start-job
