I don't know what the 1.0.0 snapshot javadocs have in them so ignore this if it's already addressed, but message.getAttributes() make no mentions of being able to retrieve http headers nor what one uses for the key name (I'm guessing the header name, but it'd be nice if the docs say so).
It'd also be nice if the methods that wrap access to the headers were more explicit about what headers they manipulate. I'm also a little puzzled at the idea of considering headers as lower-level artifacts; it seems to me that, http being an application protocol, the headers are first-class citizens. When I'm attempting to implement a spec that's based on http and it says that such-and-such a header must be set, then that's an important thing for me to be able to do. I'd also argue that it's a waste of time to try to make Restlets protocol agnostic. While REST certainly doesnt specify an application protocol, at this point there is only one and http is it. Google around for leaky abstractions and protocol independence. You'll find that true protocol-independence is rarely acheived and almost always costs more than its worth in additional complexity. (For example, how would you support an underlying protocol that doesn't have the concept of redirection - all those redirect methods become pretty useless.) But hey - you guys are the ones doing the work, so I'm not going to complain too loudly. --Chuck -----Original Message----- From: Jerome Louvel [mailto:[EMAIL PROTECTED] Sent: Monday, February 12, 2007 4:38 AM To: [email protected] Subject: RE: Re: Response Headers Hi Chuck, All standard HTTP headers have an equivalent class/property in the Restlet API. It was a deliberate choice to not expose those headers as first-class citizens, because we consider them as lower-level artifacts and because we want to support multiple protocols via the same API. However, you do have access to those raw headers via the request.attributes property. You can also add non standard HTTP headers if required. See the Javadocs for details: http://www.restlet.org/docs/api/org/restlet/data/Message.html#getAttributes( ) Best regards, Jerome > -----Message d'origine----- > De : Chuck Hinson [mailto:[EMAIL PROTECTED] Envoyé : lundi 12 > février 2007 06:36 À : [email protected] Objet : RE: Re: > Response Headers > > Umm.
