Examples

The following example shows an event handler for the CreatingCookie event. The handler retrieves user values from the CreatingCookieEventArgs object to customize the authentication cookie. The handler saves the value from the CustomCredential property in the authentication ticket and sets the CookieIsSet property to true to indicate that the authentication cookie has been created.

void AuthenticationService_CreatingCookie(object sender, 
    System.Web.ApplicationServices.CreatingCookieEventArgs e)
{
    FormsAuthenticationTicket ticket = new
          FormsAuthenticationTicket
            (1,
             e.UserName,
             DateTime.Now,
             DateTime.Now.AddMinutes(30),
             e.IsPersistent,
             e.CustomCredential,
             FormsAuthentication.FormsCookiePath);

    string encryptedTicket =
         FormsAuthentication.Encrypt(ticket);

    HttpCookie cookie = new HttpCookie
         (FormsAuthentication.FormsCookieName,
          encryptedTicket);
    cookie.Expires = DateTime.Now.AddMinutes(30);

    HttpContext.Current.Response.Cookies.Add(cookie);
    e.CookieIsSet = true;
}

Sub AuthenticationService_CreatingCookie(ByVal sender As Object, _
                 ByVal e As System.Web.ApplicationServices.CreatingCookieEventArgs)
    Dim ticket As FormsAuthenticationTicket = New _
       FormsAuthenticationTicket _
        (1, _
         e.Username, _
         DateTime.Now, _
         DateTime.Now.AddMinutes(30), _
         e.IsPersistent, _
         e.CustomCredential, _
         FormsAuthentication.FormsCookiePath)
        
    Dim encryptedTicket As String = FormsAuthentication.Encrypt(ticket)
    
    Dim cookie As HttpCookie = New _
        HttpCookie(FormsAuthentication.FormsCookieName, encryptedTicket)
    cookie.Expires = DateTime.Now.AddMinutes(30)
    
    HttpContext.Current.Response.Cookies.Add(cookie)
    e.CookieIsSet = True
End Sub

Remarks

The CreatingCookieEventArgs class supplies values to any CreatingCookie event handler. By using the properties of this class, you can retrieve user credentials when you create a custom authentication cookie.

The AuthenticationService class raises the CreatingCookie event when it sets the authentication cookie, after the user credentials have been authenticated. The AuthenticationService class constructs a CreatingCookieEventArgs object and passes it to any CreatingCookie event handler.

You retrieve the user credentials through the UserNamePassword, and CustomCredential properties. The CustomCredential property can contain any custom values that you need in order to authenticate, such as an identification number. The IsPersistent property indicates whether the authentication cookie should be retained past the current session. Set the CookieIsSet property to true if you create the authentication cookie, so that the AuthenticationService class does not create the cookie.
