HTTP Meeting Notes Tuesday Dec 10th
Chair: Larry Masinter,
Note taker: Henrik Frystyk Nielsen
Walk Through of Current Drafts
Continued from yesterday...
Cache Hit Metering Proposal
-
Jeff Mogul presented the current status of the Hit Metering
proposal
-
An important note is that the current definition of proxy
validate in HTTP/1.1 needs to be changed
-
Jeff proposed a fix "Proxy-must-check"
-
It was noted that cache-busting may not be a growing
problem and a hit metering scheme may make it worse
-
The proposal adds additional requirements on a proxy: It
has to know where a document comes from, for example. It
was discussed whether the extra overload was a problem. The
general feeling was no.
-
The issue of statistical sampling was been brought up
several times but nobody have provided a draft.
-
The limitations of the current proposal should be made
clear in the draft. If this is met then the proposal can
move forward
Safe POST / GET-with-body
-
It was discussed whether HTTP should have more properties
for handling the user-agent. There was a general feeling
that HTTP should be kept orthogonal to what goes on in the
user agent.
HTTP Related work
What is going on in other groups related to HTTP
HTTP-NG
-
Jim Gettys talked about the status on behalf of Bill
Janssen who was not present
-
Neither of the current distributed RPC systems IIOP from
CORBA nor DCOM from Microsoft is really suitable for the
Web
-
One of the main problems is scalability
-
It is being worked on but still in research
Web Server Management
-
Harrie Haxewinkel reported on definitions of managed
objects for WWW servers (Look for the APPLMIB working
group)
SHHTP
-
Chair of WTS wg reported on SHTTP. The wg has not met for
the last two IETF meetings
-
Was based on HTTP/1.0 and one of the problems why it has
been held up was due to undefined interactions with
HTTP/1.1
-
There will be an updated draft coming out and it will be
cross mailed to the HTTP-wg list
Remote pass-phrase Authentication
-
Petke (compuserve) gave an overview of the the
"Remote pass-phrase authentication" which has no passwords
in clear
-
There are four drafts available as draft-petke-*
-
The system is currently in production
-
Look for "Virtual Key" which is the slogan
SLL Tunnelling
-
The current draft for SLL tunnelling through proxies has
expired but Ari would like to resubmit it and make it an
RFC
-
There are implementations in NS and MSIE proxies and
clients and also in Apache
-
It was the overall feeling that the draft should move
forward
Distributed Authoring
(Webdav)
-
Jim Whitehead reported
-
There is a BOF Wednesday
-
Based on PUT and adding on new features for locking, link
management, relationship, attributes
-
Interacting with containers and webmaps
-
Access control and versioning
Internet Printing Protocol
-
Cral-Uno Manros reported.
-
Work in going on the same group which did the print MIB
-
Goal is to make printing available over the intenet
NMUSIC
-
There is ongoing work in NMUSIC on RTSP and SIP which looks
something like HTTP. We need to have a link
-
Keith Moore mentioned that as HTTP is getting more complex
it is difficult to role your own stuff anymore. This will
make other people have to reinvent their own protocol.
Maybe a layering of HTTP would solve this
PEP
-
Dan Connolly report that no new draft has been issued and
there was nothing to discuss at this meeting
-
People are eagerly awaiting the next draft
-
Paul Leach requested for extensions of error codes. This is
exactly what the NMUSIC group wanted
-
Jim Gettys mentioned that extensions of HTTP must be done
right. PEP or something will have to solve this
Working Group Plans
-
There a couple of months left before the HTTP/1.1 can go to
draft standard. We should work towards that date!
-
There are some minor details that should be incorporated
into the current version. Hopefully it can be recycled as
proposed
-
It was proposed that the alternate stuff was taken out of
the current content negotiation to be pu into a separate
draft and moved forward
-
Things don't have to be folded into the current HTTP/1.1 -
they can be merged later
-
Anything that relies on the version number should be added
and stuff that doesn't should be kept separate
Mile Stones
