This is still being hashed out, I think. There are basically two
possibilities that come to mind:
1. You subscribe when you create the job, and the HTTP
notification is sent back as multiple parts using the
"Content-Type: multipart/xyz" mechanism.
2. You create the subscription object separately and therefore
the HTTP notifications are POST requests sent to the specified
URI.
#2 would necessarily require an HTTP server, or if you are sending the
notification to a user app, a skeleton server that just accepts POST
requests, looks for a Content-Length: or Transfer-Encoding: line,
and receives the IPP notification packet after it sees a blank line.
The code to do this is not very difficult...
