Important
For access rules, if you selected to deny access to sites, you
can optionally select the Redirect HTTP request to the Web
page check box, and then specify an alternate URL to which
client requests should be redirected. Note that:
The URL specified must be accessible to the clients or users.
Either the URL must be on an internal computer, or a rule must
explicitly allow access to the URL.
When you specify the destination to which to redirect the
request, you can specify a different location, by typing
http://URL.
For Web publishing rules, if you select to deny traffic, then
all incoming traffic that matches the rule conditions will be
blocked.
This option applies only to Web publishing rules and access
rules.
After you click Apply in the details pane, the policy is
updated. The new policy applies only to new connections.
