Request.JSON: "X-Request" overrides "X-Requested-With" header

[mderar]

If server returns the "X-Request" after "X-Requested-With" in the "Access-Control-Allow-Headers" the "X-Requested-With" header will be ignored, thus browser will return error "X-Requested-With is not allowed by Access-Control-Allow-Headers".

My workaround was to comment out "X-Request: JSON" in the "Request.JSON.initialize()".
