" 18:55:25 But this is at odds with what I've read elsewhere about q= being used for client preferences 18:56:21 how is it at odds? it seems consistent, to me 18:57:34 q= can't mean both "Send me content with a quality markdown" and "Send me this content after this other content" 18:57:58 What if I prefer low quality audio over high quality audio? 18:58:19 that's considered irrational 18:58:32 i.e. the protocol can't express it 18:58:41 Why?! If I am on a slow connection then it's totally rational... 18:58:47 hmm 18:59:08 It seems the protocol can express it if more than one attribute were used instead of just 'q' 18:59:15 there was discussion of ways to express bandwidth limitations, but I think they didn't get standardized 18:59:23 ok 18:59:45 ryanlee (n=ryanlee@30-6-75.wireless.csail.mit.edu) has joined #dig 18:59:46 It still seems wrong that 'q' has two different meanings 18:59:54 I think the discussion is in the www-talk archives from '92 or '93 if you really want to see all the gory details. (or maybe in an http-wg archive) 19:00:28 If I prefer one type of audio over another but I still want them at high quality "audio/foo; q=1.0, audio/bar; q=0.1" may not do what I expect 19:00:50 er... audio quality is not what the protocol expresses.. 19:01:08 "quality" in the http spec refers to loss of integrity due to conversion from one MIME type to another. 19:01:51 fine, but apparently it is also used for content-type preference ordering 19:02:05 also? it's *only* used for preference ordering. 19:02:32 "SHOULD be interpreted as "I prefer audio/basic, but send me any audio type if it is the best available after an 80% mark-down in quality."" 19:02:51 Doesn't that mean that '0.8' is used for quality information too? 19:02:54 that's not saying "after adding noise to the audio signal" 19:04:06 that's saying "if you have audio/mp3 at q=1 and audio/basic at q=0.5 , send me the audio/basic, but if the audio/basic has q=0.1, then send me the mp3" 19:04:54 the 0.5 vs 0.1 is at the discretion of the server/publisher. it's not a measurable thing. 19:05:21 But the client is just using arbitrary 'q' values to rank their preferred content-types 19:05:38 yes, and the server is using arbitrary 'q' values to rank their preferred content types. 19:05:56 but these are not the same set of arbitrary values 19:06:03 no? 19:06:24 by virtue of the fact that both parties agree to the HTTP spec, they are. 19:06:53 if the server says "audio/mp3 is 0.8 and audio.basic is 0.1" 19:06:58 but the client doesn't know this 19:07:07 and just uses arbitrary values for ranking purposes only 19:07:19 then whatever semantics the server has assigned will be unknown to the client 19:07:25 yup. 19:07:32 and will be invoked with possibly incorrect results 19:07:47 because 'q' expresses both ranking and quality 19:07:55 well, results that are sub-optimal by some other measure, but they'll be correct per http 19:08:12 so then it seems like the spec is brain-damaged here 19:08:35 unless there is some way to untangle quality and ranking that I don't know about 19:08:35 well, it has limitations. but you don't see that it works for most cases? 19:09:02 It seems like the quality aspect of 'q' can and should be handled by other content-type attributes 19:09:05 the spec treats preference and quality as the same thing. it's a simplifying assumption that works in most cases, no? 19:09:10 and that most people just use it for ranking 19:09:21 most people never use this part of HTTP at all. 19:09:36 Sure... that doesn't really excuse it, though 19:10:12 well, yes, it does: why should the spec be even _more_ complicated when, to first (or 2nd or 3rd..) order, noone will use the extra complexity 19:10:13 ? 19:10:51 it's always possible for to use more round-trips; the server can always respond with 406 "well, here's what I've got; you decide". 19:10:59 I would argue it would actually be simpler: 'q' would mean one thing and one thing only 19:11:38 it does mean one thing and one thing only: it tells you which variant to pick. 19:11:48 you just don't like what it means. ;-) 19:12:17 You're right, I don't 19:12:20 because it's wrong 19:12:21 ;-) 19:12:51 well, hop back in your time machine and get involved in the design discussion. ;-) or change a billion web server installations ;-) 19:13:29 don't hold your breath ;-) 19:13:49 actually, there is some TCN/transparent-content-negotiation thing out there... 19:14:01 ... it's complicated that I never looked at it closely.
