I have an ASPX-based web site in which Authorize.Net has been implemented via the DPM Method.
Everything is working except that I cannot get the response to redirect properly to my site. The response URL is fully qualified (e.g., "http://www.sitename.com/callbackpage.aspx"). That page does not have any visible UI - it merely collects the Authorize.Net transaction information and redirects to a result page. When the result page is displayed, the master page css stuff is completely missing, and the browser url is still showing the authorize.net page name.
How can I get this to work correctly?
