The Banned URLs dialog box identifies which Uniform Resource
Locators you want the Internet Filter module to block whenever you
or someone else tries to connect to them.
By default, the list includes two domain names that download
hostile Java or ActiveX objects to your machine as soon as you
connect. You can add other domain names, then password-protect
your settings to ensure that users do not delete them.
URLs specify the domain name and location of a computer on the
Internet, usually together with the “transport protocol” you want to
use to request a resource from that computer. A complete URL for a
website, for instance, would look like:
http://www.domain.com
The complete URL tells your browser to request the resource via the
Hyper Text Transport Protocol (“http://”) from a computer named
“www” on a network domain named “domain.com.” Other
transport protocols include “ftp://” and “gopher://.” The
Internet's Domain Name System translates URLs into IP addresses
using an up-to-date, centralized, and cross-referenced database.
To add a site to this list, you must enter the domain name by itself,
since the module will assume you mean the Hyper Text Transport
Protocol (HTTP). To change the list, you can:
– Click
Add
to open the Add URL dialog box. Next, type the URL
you want to add to the Banned URLs list in the in the dialog
box that appears (
Figure 4-35 ). Click OK to return to the
Banned IP addresses dialog box.
Figure 4-35. Add URL dialog box
– Select one of the items shown, then click
Delete
to remove the
item from the list.
When you have changed the banned list so that it has all of the
addresses you want to block, click
OK to return to the Internet Filter
Properties dialog box.
