Quick update: it has something to do with the fact that its an AJAX request at the end... or because its a POST, one or the other... I built a URL with the parameters as a query string, and it worked fine... I don't know what it is yet yet, exploring now... the request looks identical aside from method, which shouldn't matter, AFAIKT, but something is obviously bad with it... will let you know when I figure it out...
