On the call today, we discussed about user choice on setting the DNT header. (Thinking out loud, not a strong opinion) Basically the header sets DNT: 1 and along the way a proxy modified the header for DNT: 0 the final server knows only the last value and then might not be able to behave according to user choices. * CGI Roy proposed on IRC to have a cgi script on the final server displaying what headers it has received. Issues because it means the user has to understand what is happening. * Echo another possibility would be having the server sending back in the response a header with the original DNT header. Server sending something like (not the formal syntax) DNT-received: 0 This has issues too. Ian Fette will say too heavy? And a proxy can still modify it on the way back too. -- Karl Dubost - http://dev.opera.com/ Developer Relations & Tools, Opera Software
