• Block Cookies—Cookies are used to store session information by websites
that usually require login. However, several websites use cookies to store
tracking information and browsing habits. Enabling this option filters out
cookies from being created by a website.
NOTE: Many websites require that cookies be accepted in order for the site to be
accessed properly. Blocking cookies can cause many websites to not function
properly.

Adding Trusted Domains
You can add a list of trusted domains. These domains are bypassed during
keyword filtering. For example, if “yahoo” is added to the blocked keywords list
and www.yahoo.com is added to the trusted domain list, then www.yahoo.com
will be allowed, but mail.yahoo.com will not be allowed.
NOTE
Before adding trusted domains, you must enable content filtering. See Enabling
Content Filtering, page 85 .
To add trusted domains:
STEP 1
Choose Firewall > Content Filtering. The Trusted Domain Table displays a list of
currently configured trusted domains.
STEP 2
Click Add and enter the name of the trusted domain.
STEP 3
Click Save.
Configuring URL Blocking
You can block access to websites that contain specific keywords in the URL or
page contents. If these keywords are found in the site's name (for example, web
site URL or newsgroup name), the site is blocked. To configure URL blocking:
STEP 1
Choose Firewall > URL Blocking . The table displays currently blocked keywords.
STEP 2
Click Add Row.
STEP 3
Under Status, check the box to enable blocking for the new keyword.
