status code of response using RPC

[talial]

Hi,
This might be a question connected more to GWT...but maybe someone can help.

I'm using RPC AsyncCallback to perform calls from client to server, it eventually returns the result or throws an exception.
when RPC fails I need to get the error status code of the response to
distinguish a case of 302 code.
I'm looking at the InvocationException that is thrown in this case but
there is no indication to the error code.
Is it possible to get the response status code when RPC fails? or distinguish the redirect case in any way?

Thanks,
Tali
