how to redirect guest to guest.aspx from login

I have an administrator and a guest user...

When the administrator logs in he should be redirected to the default.aspx but if the guest logs in he should be redirected to the guest.aspx page... Currently it is being redirected to Default.aspx...

here is my code

web.config

authentication mode="Forms">
    <forms loginUrl="Login.aspx" protection="All" name="Cookie" timeout="120" path="/" slidingExpiration="true"
       defaultUrl="Default.aspx">
    </forms>
  </authentication>

Login.cs code

 System.Security.Principal.WindowsIdentity wi = System.Security.Principal.WindowsIdentity.GetCurrent();
                System.Security.Principal.WindowsPrincipal wp = new System.Security.Principal.WindowsPrincipal(wi);


                if (wp.IsInRole("Administrators"))
                {
                    BadCredentials.Visible = false;
                    Session["userName"] = UserName.Text;
                    Session["password"] = Password.Text;
                    Session["domain"] = Domain.Text;


                    string role = "Administrators";

                    // Create the authentication ticket
                    FormsAuthenticationTicket authTicket = new FormsAuthenticationTicket(1,                          // version
                                                   UserName.Text,           // user name
                                                   DateTime.Now,               // creation
                                                   DateTime.Now.AddMinutes(60),// Expiration
                                                   false,                      // Persistent 
                                                   role);         // User data

                    // Now encrypt the ticket.
                    string encryptedTicket = FormsAuthentication.Encrypt(authTicket);
                    // Create a coo开发者_如何学Ckie and add the encrypted ticket to the

                    HttpCookie authCookie =
                                 new HttpCookie(FormsAuthentication.FormsCookieName,
                                                encryptedTicket);

                    // Add the cookie to the outgoing cookies collection.
                    Response.Cookies.Add(authCookie);

                    // Redirect the user to the originally requested page
                    Response.Redirect(FormsAuthentication.GetRedirectUrl(UserName.Text, false));

                }
                else if (wp.IsInRole("Guests"))
                {
                      BadCredentials.Visible = false;
                Session["userName"] = UserName.Text;
                Session["password"] = Password.Text;
                Session["domain"] = Domain.Text;

                string role = "Guests";

                // Create the authentication ticket
                FormsAuthenticationTicket authTicket = new FormsAuthenticationTicket(1,                          // version
                                               UserName.Text,           // user name
                                               DateTime.Now,               // creation
                                               DateTime.Now.AddMinutes(60),// Expiration
                                               false,                      // Persistent 
                                               role);         // User data

                // Now encrypt the ticket.
                string encryptedTicket = FormsAuthentication.Encrypt(authTicket);
                // Create a cookie and add the encrypted ticket to the
                // cookie as data.
                HttpCookie authCookie =
                             new HttpCookie(FormsAuthentication.FormsCookieName,
                                            encryptedTicket);

                // Add the cookie to the outgoing cookies collection.
                Response.Cookies.Add(authCookie);

                // Redirect the user to the originally requested page
                Response.Redirect(FormsAuthentication.GetRedirectUrl(UserName.Text, false));

            }

how do i get another URL for the guest....

any suggestions?? thanks..

In your guest section replace:

// Redirect the user to the originally requested page 
Response.Redirect(FormsAuthentication.GetRedirectUrl(UserName.Text, false)); 

With:

// Redirect the user to the originally requested page 
FormsAuthentication.SetAuthCookie(UserName.Text, false)
Response.Redirect("guest.aspx", true);
