RE: [Sip] Privacy statements and History(draft-ietf-sip-history-i nfo-04.txt)

["Mary Barnes" <[e-mail]>]

Hi all,
 
I've again snipped the thread, but did want to propose the change that I
think will satisfy the concerns raised.
 
The change proposed is to change the last statement in the first paragraph
in section 4.3.3.1.1 from:
"...the proxy MUST remove any hi-entry(s) prior to forwarding."
to:
"...the proxy SHOULD remove any hi-entry(s) prior to forwarding, depending
upon local policy and whether the proxy might know apriori that it can rely
on a downstream privacy service to apply the requested privacy." 
 
So, unless further concerns are raised on this proposed change, I'll plan on
incorporating that with any other last call comments in the -05 version.
 
Mary

Mary, Sebastien, Roland, 
 
I agree that we should let the possibility for a proxy not to remove the
hi-entry even if privacy is requested and even if the request is forwarded
to a Request-URI associated with a domain for which the proxy is not
responsible (if there is an agreement between the domains that ensures the
proxy that privacy will be applied to the request). 
I suggest a text that would look like (in case privacy is requested): "the
hi-entry SHOULD be removed by the proxy unless it knows that it can rely on
a downstream privacy service to apply the requested privacy ".
 
Sebastien.

I still contend that the SHOULD is sufficient.  SHOULD means that in general
processing, if the hi-entry has a privacy header, then the usual processing
would be that it would be removed (i.e it was added for a specific reason
and in general should be used to remove the entries based on well defined
criteria).  If there are reasons, such as local policy, that would allow the
forwarding in specific cases, then it's okay that it is forwarded.  I think
the use of MAY results in less precision and I think the value and critera
for associating and removing the privacy header with the hi-entry becomes
much less clear.  

I'd like to hear more opinions on this topic, prior to agreeing to making
the change (from the MUST to MAY rather than MUST to SHOULD). 

Regards, 
Mary

Mary and roland, 

Actually, the statement regarding the forwarding of hi-entries beyond the
domain for which the proxy is responsible should rather be a matter of local
policy and thus a MAY should be used instead of SHOULD. We are potentially
dealing with network boundaries where agreements for forwarding such kind
information can be reached. 

Section 4.3.3.1.1 
This section should be re-reworded in accordance with the statement above (I
can provide some text is we can agree). 

Section 4.3.3.1 is ok (apologies for not being explicit) 

Best regards, 
sébastien
