Hi,I have exactly the same question and I have been browsing numerous forums but I haven't fount a satisfactorily answer. Iframes cause major security risks since user details are passed via the URL. I looked into Sessions or Cookies in order to provide some security but DotnetNuke seems not to use Sessions to store user credentials but instead uses encrypted cookies. I haven't been able to use that in my own ASP pages to verify the user credentials. I think the reason there are no answers to this question is the fact that I want to use DotnetNuke for the wrong purpose. I.e. integrating it with my own developed ASP pages. It would have been nice if Dotnetnuke used Sessions which can than store user credentials which can then be used in other non DotNetNuke pages. Anyone has experience adapting DotNetNuke to use Sessions?Regards,Peter
