Hi Jonathan, I've entered an issue for this interesting proposition.
http://restlet.tigris.org/issues/show_bug.cgi?id=984 Best regards, Thierry Boileau > I wish to propose another tunnel which is a bit more practical in > dealing with browser Accept header quirks. > > At present, browsers implement the accept header oddly. > > to quote Jon Blower's recent email to the list: > > "Firefox 3: Accept header is > "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8". > Hence text/html is used, as expected. > > Chrome 0.2.149.30: Accept header is > "text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5". > So Chrome prefers application/xml to text/html and hence gets an XML > representation by default. Seems odd. > > IE7: Accept header does not include text/html, image/png or > application/xml (!!) but does include "*/*" (yuck) so IE gets the > variant that happens to be first in the Resource's list. With the > above code this just happens to be text/html. So conneg doesn't > really happen here at all." > > The current way of dealing with this is to use the User Agent (ua) > string and then 'fix-up' the accepted media. > > However, we have unknown browsers, or companies who change the ua string > of known browsers, or future versions that change the ua string, > different ua strings for different os, etc. This is hard to maintain and > leaves us open to serving incorrect representations to our users. - > which happens with chrome at the moment. > > An alternative I suggest would be to ignore the accept header and > provide html unless the person sending the request has gone to lengths > to send something specific. At lengths could mean where the accept > header did not contain any mention of html or xhtml at all. Then they > would be shown the representation they requested in the accept headers. > > This could be wrapped up in a tunnel like setUserAgentTunnel() and be > off by default. It would be an 'either or' to have this or the User > Agent Tunnel on. > > Any thoughts or opinions? > > Jon > > ------------------------------------------------------ > http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=2430633 > > ------------------------------------------------------ http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=2430812
