>If I understand what you're saying, this works fine today, with the existing model. For example, in our implemenation, these two Request-URIs sent to Host carlk:
/servlet/IPPServlet/vega-lp
/servlet/IPPServlet/pp4019
both cause the web server on carlk to invoke servlet IPPServlet. IPPServlet uses the path info from the Request-URI to determine if the target output device is "vega-lp" or "pp4019".

So unless there are strong arguments to the contrary, the protocol document will state that the request-uri has the same value as the printer-uri/job-uri in the operation.
Then Randy agreed, and the thread ended.
