You don't. That's handled entirely by the client (e.g. IE).

I don't think such a thing is really feasible as you envision it. We could
present a page if the login fails. But there's no way to tell if the
client supports transparent authentication. Meaning Firefox would still
present the password dialog. The logon page would only appear after the
user entered bogus creds and the login failed.

I think using the user agent information is your best bet.
