  • Reference

Definition

Namespace:
System.Web.Security
Assembly:
System.Web.dll

Gets a value that indicates whether the application is configured for cookieless forms authentication.

public:
 static property System::Web::HttpCookieMode CookieMode { System::Web::HttpCookieMode get(); };
public static System.Web.HttpCookieMode CookieMode { get; }
static member CookieMode : System.Web.HttpCookieMode
Public Shared ReadOnly Property CookieMode As HttpCookieMode

Property Value

HttpCookieMode

One of the HttpCookieMode values that indicates whether the application is configured for cookieless forms authentication. The default is UseDeviceProfile.

Examples

The following code example sets the cookieless attribute to AutoDetect in the Web.config file.

<authentication mode="Forms">
  <forms loginUrl="member_login.aspx"
    cookieless="AutoDetect" />
</authentication>

Remarks

The CookieMode property reflects the value for the cookieless attribute of the forms configuration element. The CookieMode property determines whether the FormsAuthenticationTicket value will be stored in a session cookie in the browser or stored in the QueryString property.

Note

When the FormsAuthenticationTicket value is stored in the URI, the length of the generated URI may be longer than the maximum length allowed. This is most likely to occur when the FormsCookiePath property is set to the application name and the application name is long (40 or more characters), when user names in the application are long, or when long UserData strings are stored in the FormsAuthenticationTicket value. If the generated URI is too long, the Web server will return a 400 - Bad Request error.
