7.5.4. Filters
By default, you have control over what sites are ALLOWED (whitelist) and what sites are
BLOCKED (blacklist) and some control over content filtering without having to enable
compression.
There are three filter categories:
•
Fragile Sites:
list sites that you want the content kept intact without any
modification.
•
Sites Blocked:
the blacklist; users are prevented from viewing these sites.
•
Sites Allowed:
the whitelist; these sites are allowed for viewing. This list
overrides the blocked list.
Filters respond to POSIX Regular Expressions. Example: If you place a slash ( / ) in Sites
Blocked then the entire Internet is blocked (blacklist). Enter the whitelist in the Sites
Allowed section. If any of the allowed sites should be accessed without any content
filtering, enter that site in the Fragile sites section as well.
