[vb.net] problema autenticazionie con ricordami

[Kahm]

confermo che il cookie non va letto.

il framework che ci sta a fare ?

sul riconoscimento successivo, lo fa lui in automatico..

è che devo far visualizzare il nome di chi si è collegato
quindi per sapere chi è l'utnte devo leggere o no?

in effetti è vero, non ho messo la data scadenza del cookie , ma anche impostandola mi da lo stesso problema, ecco le mie aggiunte

  
<authentication mode="Forms">          <forms loginUrl="login.html" defaultUrl="index.aspx" cookieless="UseCookies" timeout="9000" />        

</authentication>

scrivo:

    
Dim ticket As FormsAuthenticationTicket = New FormsAuthenticationTicket(                1,                                     ' ticket version
                Login1.UserName,                              ' authenticated username
                DateTime.Now,                          ' issueDate
                DateTime.Now.AddMinutes(30),           '/ expiryDate
                True,                          ' True to persist across browser sessions
                "userData",                             ' can be used to store additional user data
                FormsAuthentication.FormsCookiePath)  ' the path for the cookie

            Dim encTicket As String = FormsAuthentication.Encrypt(ticket)
            Dim cookie As HttpCookie = New HttpCookie(FormsAuthentication.FormsCookieName, encTicket)
            cookie.HttpOnly = True
            Response.Cookies.Add(cookie)

            Response.Redirect(FormsAuthentication.GetRedirectUrl(Login1.UserName, True))

leggo

 
 Dim FormsAuthCookie As HttpCookie = Request.Cookies(FormsAuthentication.FormsCookieName)    
            If Not FormsAuthCookie Is Nothing Then

                    Dim usr As String = FormsAuthCookie.Value
                    Dim Ticket As FormsAuthenticationTicket = FormsAuthentication.Decrypt(FormsAuthCookie.Value)

                    Dim roles As String() = Ticket.UserData.Split(New Char() {"|"})
                    Dim ID As IIdentity = New FormsIdentity(Ticket)
                    Dim principal As IPrincipal = New GenericPrincipal(ID, roles)
                    Context.User = principal

                    usr = Ticket.Name & ""
