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

• 2/97 Hit Metering to IESG
• 2/1/97 New drafts on remaining isses and problems in HTTP/1.1
• 2/1/97 PEP draft
• 2/1/97 Content Negotiation draft
• 3/1/97 New 1.1 suite of documents going to IESG
