In addition to the http notification mechanism that you described recently,
we have also discussed a mechanism where the subscription contains the url
of the recipient. The url has a new scheme, such as "ipp-notify:". The
event sender opens a connection to the host:port specifed by the url and
sends a message encoded in the same fashion as a message body part of an ipp
request (i.e. like an ipp request but without the request line and http
headers).
What are your thoughts on this mechanism for sending events?
