true if the authentication cookie was created; otherwise, false.
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 CookieIsSet property is set to true after the authentication ticket is 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 AuthenticationService class checks the CookieIsSet property to determine whether the authentication cookie has been created. You set this value to true if you create an authentication cookie in an event handler for the CreatingCookie event. If CookieIsSet is set to false (the default value), the AuthenticationService class creates an authentication cookie, This overwrites any cookie that you have created in the handler for the CreatingCookie event.
