I do have a significant comment on this draft, because of decisions
in the final version if draft-ietf-sip-sips that fix some of the bugs
hightlihted in this draft (and remove a use case for double record route).
I believe those changes fix BUG 734 and BUG 735 as listed by Robert.
Since draft-ietf-sip-sips does NOT use double record routing
anymore (in fact, it prohibits mapping from sip to sips), references
to this effect need to be removed from the document. Specifically:
- In section 1:
- In first paragraph, delete ", sip to sips".
- Please delete the fourth sub-bullet.
- Section 3.2: I believe the following sentence in the 4th paragraph
shall be deleted:
"Then, this section speaks about record-route requirements
when transiting from sips to non-sips. It's not clear that the
section doesn't apply to TLS to non-TLS transitions where SIPS is not
involved (see [BUG734]).".
Later in this section, you quote the following paragraph from RFC 3261/
section 16.7 bullet 8:
"If the proxy received the request over TLS, and sent it out over a
non-TLS connection, the proxy MUST rewrite the URI in the Record-
Route header field to be a SIPS URI".
As per draft-ietf-sip-sips-08/Appendix B, this whole paragraph has
been deleted as a "Bug fix". So you should remove it from the text
(and maybe refer to it's removal as per draft-ietf-sip-sips-08).
Furthermore, ther paragraph right after should thus be reworded as
follows:
Indeed, [RFC3261] suggests rewriting the Record-Route header in
responses.
(i.e., everything starting with ", and mandates..." until the end of the
paragraph is deleted.
I believe this means that BUG734 and BUG735 has been adressed by
draft-ietf-sip-sips-08 since mapping between sips and non-sips has been
deprecated.
- In section 4, change the last sentence to "This recommendation
applies to all uses of Record-Route rewriting by proxies, including
transport protocol switching and multi-homed proxies."
I would like these changes do be done before WGLC.
