Property Value

One of the HttpCookieMode values. The default value is UseDeviceProfile.

The Cookieless property defines when a cookie should be used to maintain information about the user.

When the Cookieless property is set to UseCookies, the user's identifier is stored in a cookie. For more information, refer to HttpCookieMode.


ASP.NET stores the user's anonymous identifier within the URI path (that is, it runs in cookieless mode) if the Cookieless property is set to one of the following values: UseUri; UseDeviceProfile when the browser profile indicates that cookies are not supported; or AutoDetect when the auto-detection process determines that the browser does not support cookies. Finally, if the size of the URI and the anonymous identifier exceeds the allowed length, the anonymous identifier is not applied.

The following code example demonstrates how to access the Cookieless property.

// Get Cookieless.
System.Web.HttpCookieMode cookieless =
Console.WriteLine("Cookieless: {0}",
