Hello Peter,

We have talked about this topic on stackoverflow. I have a quick question on the IPN Servlet. PayPal IPN Guide recommends that the IPN receiver guard against duplicate IPNs from PayPal (that can be sent in some cases). Is there anything in the servlet to guard against duplicate notifications?

Thanks.
