Control web content by creating web content filter lists that control access to web pages
containing specific words or patterns. You can add words, phrases, wild cards and Perl
regular expressions to match content on web pages.
For information, about wild cards and Perl regular expressions, see
Perl regular expressions" on page
Note: Perl regular expression patterns are case sensitive for the Web content filter. To
make a word or phrase case insensitive, use the regular expression /i. For example,
/bad language/i blocks all instances of bad language regardless of case. Wildcard
patterns are not case sensitive.
For each pattern you can select Block or Exempt. Block, blocks access to a web page that
matches with the pattern. Exempt allows access to the web page even if other entries in
the list that would block access to the page.
