Your problem is that you're calling objectToString on the
XMLHttpRequestObject. You can't do that. The XMLHttpRequest object
has enumerable properties that you don't have permission to access
from the browser (which is why it says permission denied). You'll
have to write a version of objectToString that does a try{}catch{} in
the loop so that it skips properties that you do not have access to
view.
