Hi,
I am in a situation where I need to get XML string of each product from server side on request, but only those tags that are added to XML at server side after the last client request. How can I determine at server side and return only newly added tags of XML of requested product to client so that only latest and relevant information could be shown at client side. And is there any way to save and keep on updating that XML data retrieved for each product on client side?
