gets made without first being raised as an issue and listed as such. I hope this 
will make tracking of changes easier. Rather than issue lots of drafts and have 
people comment on different ones I think this might work better. I'll try and 
close off each set of additions on an approximately fortnightly basis.]

The problem here being how to define the manner in which the name is obtained.
Some people are using cookies to abtain authentication names...

It is an oversight though..

Adding to the
complexity, it would seem different prefix-identifier combos would mean
slightly different things based on whether one was viewing a log file for a
origin server, or a proxy server.

The ide was to try to avoid this. A client and a server should be able to use 
the same format and the same fields mean the same thing. This is why I chose cs 
for client-to-server instead of in and out. (years of hacking code for big MIMD 
processors).

This should be s-dns or c-dns. I tried to fix this in the draft. some sort of 
matrix showing which prefixes are valid is needed. Is it nonsensical given the 
addition of the "s-" and "c-" prefixes? Yes these should be explicitly ruled out 
as invalid.

I would suggest placing an x- in front to avoid the slight chance of a name 
collision in a future version of the spec.

Yes, I adgree, I've been looking at the CL-HTTP server on this exact topic..

OK.. even better!

Yes, I would have thought implicitly in the HTTP spec??

Good plan! How to do it though? Perhaps we could have a - trailing the close 
quote "http://fooooooooobaaaaaar.com/vvvvvvvvvvveerrylllllonggggg"-  ?? Or is 
that liable to be awkward for parsers? How about "!" or ~ ? Feelings anyone?
