We know nginx can proxy WebSocket since version 1.3.13, and we also know some times WebSocket server will valid the 'Origin' header, so someone said you can do something like:
proxy_set_header Origin "";
render the origin header to null, but I test it using my Wheezy box(nginx-extras package in backports), and there is a negative result, server side still get the Origin header from client side.
So here is the question: that line does not work, right?
