Hi, Iam working in a webapplication in which I am using RSA cookie authentication to login. I login using secure RSA ID in which i login using different users with different Tokens such as Admin , client etc.., for ex.. if i login using Admin account and RSA pincode i have to redirect to a different destination page than that of the client account's destination page. The thing is that i have written RSA secured Cookie for login in a page called Authorize.aspx as follows in the HTML page of Authorize.aspx: <% Dim RSACookieAPI '//Response.Cookies["RSACookieAPI"].Expires = DateTime.Now.AddYears(-30) RSACookieAPI = Server.CreateObject("Rsacookieapi.RSACookie") %> Hello <%=RSACookieAPI.RSAGetUserName() %> <% session("rsauser")=RSACookieAPI.RSAGetUserName() %> <% Response.Redirect("auth.aspx") %> My question is that when i click logout in the destination page for each account the RSA cookie's time frame and user's session should expire and come to the home page. I don't know how to end the RSA cookie's session as i have different accounts in each page from which i logout. So pls help me with this issue. i think i have confused u a bit with my question. Sorry for that. pls help me with this issue. Thanks and Regards Vijay.

Hi, When we open a Word document as a link in a secure (https://) area of our website, we get a "Choose a digital certificate" window which pops up when i try to open the Word document. The message says "The Website you want to view requests identification. Please choose a certificate." However, there are no certificates listed in the window below the message. The certificate is not expired. I only get the error on Word documents (not PDF or Excel documents) and it only happens the first time you click on a link. If I reopen a Word document which just gave me an error, I will not receive the error the second time around. Our browser security is set to Medium and I did add our secure website to the Trusted Sites. Pls sort out this issue. Regards Vijay.

So pls help me.
