Hi guys, all good?

I'm enabling CORS for my web frontend but seems that I'm missing something on Kibana  
as I observe the following error:

> Courier Fetch Error: unhandled courier request error: Authorization Exception in Chrome/Safari on Kibana 4.5.0

```
# Cors CONFIG
http.cors.allow-origin: /https?:\/\/localhost(:[0-9]+)?/
http.cors.allow-methods : OPTIONS, HEAD, GET, POST, PUT, DELETE
http.cors.allow-headers : X-Requested-With,X-Auth-Token,Content-Type, Content-Length
http.jsonp.enable: true

```

Any clues?  
Thanks!

Kibana passes a header called `kbn-version` for xsrf protection. Can you try adding that?
