How to simulate/test AJAX exception handler?

I have a PrototypeJS AJAX request like this (third party code):

new Ajax.Request(url,
{
    method: 'get',
    onException: function(transport, e)
    {
        //...
    },
    onComplete: function(transport)
    {
        //...
    }
});

and want to test the behavior of onException. I have control over the server side, so I can change the response. But simply returning a 500 status does not do the trick, it is still handled by onComplete.

So what possibilities do I have to trigger the onException handler?

onException is only fired when there was an exception while dispatching other callbacks, see here, in Ajax response callbacks. So I'm not sure there is a way to test it.

EDIT:

I read (in french, didn't find anything in english) that if you make a cross-domain request it fires the vent.
