Hi all,

can anybody please confirm my following assumptions on some URIs in
SUBSCRIBE/NOTIFY messages:

SUBSCRIBE is a dialog creating method and therefore the addresses sent in
the Contact-header of the request and the response should be used as request
URIs in subsequent requests. Therefore 

1. A NOTIFY-request should use the URI of the Contact-header of
SUBSCRIBE-request as Request URI.

2. SUBSCRIPTION refresh requests should use the URI of the Contact-header of
the 200-response to SUBSCRIBE as Request URI.

3. If the same UA also uses PUBLISH-requests, it should also adhere to the
above rules and use the URIs exchanged in the Contact-headers of existing
SUBSCRIPTION based dialogs.

Unfortunately RFC 3265 does not address this point explicitly and there is
also no example message flow in RFC 3265.

Thank you for clarification or (hopefully) confirmation.

Franz

PS: The background of my question comes from an irritation when I look at
the details of the examples in "draft-ietf-simple-publish-01.txt". I think
there are some corrections necessary regarding the request URIs and URIs in
From- and To-headers.
