In addition to using the Web Security appliance to monitor and block traffic to certain
websites, you can also use it to redirect users to a different website. You can configure the
appliance to redirect traffic originally destined for a URL in a custom URL category to a
location you specify. This allows you to redirect traffic at the appliance instead of at the
destination server.

You might want to redirect traffic at the appliance if your organization published the links to

Note — Beware of infinite loops when you configure the appliance to redirect traffic. For
example, if you redirect traffic destined for http://A.example.com to http://B.example.com and
you also inadvertently redirect traffic destined for http://B.example.com to http://
A.example.com, then you create an infinite loop. In this case, the appliance redirects the
traffic back and forth between the two URLs indefinitely.
