Using the Block and Accept Filters 67
The following table describes the parameters on this page. Click Save Changes after making any
changes.
Note the following about content filtering:
• You can enter multiple lines for each filter, but each line should contain one regular expression
or word. Each line is applied independently.
• HTML comments and tags imbedded between characters in the HTML source are filtered out so
content filtering applies to the actual words as they appear when viewed in a Web browser.
