        }
        else
        {
            labelText = "Browser does not support cookies on redirection.";
        }

        Label1.Text = labelText;
    }

Remarks

With UP.Browser 4.1 or UP.Browser 3.2, the Redirect method behaves as if the value of the SupportsRedirectWithCookie property of the HttpBrowserCapabilities object is false, unless the Cookieless property in the SessionState section of Web.config has been explicitly set to true.

In ASP.NET 1.1, the options for this setting were true or false, but with ASP.NET 2.0, the choices are expanded, and AutoDetect is now the default setting. If your Web application has the cookieless attribute of the <sessionState> section in the Web.config file set to a Boolean value, Redirect should work as expected for these browsers.
