NT Authentication Dialog for Site

[JemimaChadwick]

Hi,
We are developing an intranet site. We use "Basic Authentication (Windows authentication)" for authorizing entry into the application.

When session expires, we want the authentication to happen again. Since the "Request.server" variable values are already set, the pop up dialog box does not happen. We do not have a custom login page.

Can you please let us know how this can be done?

Thanks,
Jemima.

I believe what happens is that the web browser actually is the one catching the username/password on the first successful login, then resending it everytime the server asks for another login - pretty much every further authenticated page. You can run a packet sniffer on the browser to make sure, but since you can use authentication on static html pages that don't have anything to do with ASP, I'm pretty sure that is the case.
