Ok now I understand. I am not sure, but I think there is no way but
checking the request-content.
The only way i found, is to not set the 'update'-option but instead
using the 'success'-option like this:
'success' => 'if (request.responseText != "") {$
("refresh_response").innerHTML = request.responseText}'
It's not really beautiful, but should be a good workaround.
Maybe someone else shows up with a nicer solution, your problem should
be a common problem.
