This is an entirely site-specific function; there's no generic way to do it.
If you can identify a safe password-protected page on the site (e.g. /), you
can do a complete HTTP transaction on that page using the HTTP HEAD command
and see if you get a success code. Unless you're calling GetResponse lots of
times for every Connect and you server supports keep-alive, you'll be
doubling the work for every useful transaction.
