That's what I thought, except when I was working on Jot (my RESTful blog system) someone (forgot who) said that 400 indicated a problem with HTTP layer itself...
... a ... talks ... it ... Well all 4xx codes indicate a problem with the request. Have you got a specific example? Do you mean something like missing required...
Ah, Seairth was asking *that* question. I didn't realize. We should add this to the FAQ, as we've had this twice before I think. Sometimes it's 400,...
... RFC2616 says: "The request could not be understood by the server due to malformed syntax. The client SHOULD NOT repeat the request without modifications." ...
Mark, What would you be telling intermediaries if you used 200 to reply to a POST of some malformed content: a. that something was successfully appended or...
Hey Walden, ... b, I'd say, keeping in mind that "successful data processing" can include the determination of some "invalid" information within that data,...
So far, all I am seeing is that just about everyone has a different take on whether to use 400, 403, or 409 (and maybe even 200 for POSTs). I realize that...
Mark, ... Well, in my *inexperience* that looks like a loss of visibility. I understand syntax error to be a condition that aborts meaningful processing, and...
... I just don't think that it is a WebDAV specific problem, so I would expect WebDAV to use whatever status would be appropriate for any other HTTP...
... So you think this is wrong because WebDAV added a new status code? I can't agree -- the whole point of WebDAV is to *extend* HTTP/1.1 (with new methods,...

... It seems that this is just a shortcoming in HTTP. 4xx is for client errors. We are definitvely talking about a client error. In the absence of a more ...
Why isn't the correct response 415 (Unsupported Media Type)? Your application requires that the POST conform to a particular schema and that schema has been...
Seairth, I just took a look at your blog and your comments on Jot/ReSTful blog architecture and at RNA <http://www.seairth.com/blog/industry/49> and ...
Okay... now we are up to: 400 or 403 or 409 or 415 (or sometimes 200) I am unsure about using 415, though. If someone POSTs/PUTs an "text/xml" request entity...
... Agreed. If the state was transferred such that it was "processed", then it's a success. One can, I believe, quite reasonably define "processed" to...

... Even in the latter case, I'd say it's just fine. If your application only consumes well formed XML on POST, then you *may* want to use 400, but 200 would...
If 415 means only that the server doesn't like the content-type header, its a pretty worthless status code. Following ward cunningham's FIT model for...
Ok. I was making a semantic/architectural point but your point about '#' is completely valid. Any reason not to replace '#' with ';'? More to the point, any...

Yes, the echo/atom API work is in fact what started me thinking about MoST. My point is that we should not need an Atom API and a RSS API and a Wiki API and a...

As I understand it, MoST is a data driven standardised interface. Stuck to xml. But I've allway understood ReST in this way. if you get a uri, you receive a...
