Language Header not the same after AJAX/POST

[[email protected]…]

when I echo the HTTP_ACCEPT_LANGUAGE directly in my browser it says "da-DK". But when I send an AJAX/POST to the server, the header it receives is just "da"

this is an example of how my jquery .post code looks like: $.post("whatever.php", {action : 'check-login'}, function(data){

console.log(data);

});

I have asked on StackOverflow, the URL to the post is: ​http://stackoverflow.com/questions/9047075/http-accept-language-header-ie8

Seems like StackOverflow is the best place to solve this, there's no indication it's due to a jQuery bug and no test case was provided.
