authenticate again if the user is
blocked from a website due to a
restrictive URL filtering policy.

includes a link that allows them to
enter new authentication
credentials. If the user enters
credentials that allow greater
access, the requested page appears
in the browser.

blocked due to restrictive URL
filtering policies. It does not apply
to blocked transactions by subnet
with no authentication.
