I've run it through our variant of Vapour re. Linked Data verification: http://bit.ly/1gM7oYa .
Nearly there. Your use of 302 is what's going to trip up existing Linked Data clients. Why aren't you using 303 for redirection?
There actually is a 303 *and* a 302, and in the wrong order. The ops guys had some issues coming up with the correct rewrite rules, and then it got stuck, I'm afraid.
