Open Stack

Hi Adrian,

Good to know this is a known issue.

Why does the client need to see custom headers from the server anyway?
I know the client needs to pass the authorisation header to the server, but
I haven't seen any of the APIs yet that return custom headers. (It's likely
I'm missing them though)
