Web filtering
When you enable Anti-Virus & Web filter in a firewall policy, you select a content
profile that controls how web filtering behaves for HTTP traffic. Content profiles control
the following types of content filtering:
• blocking unwanted URLs,
• blocking unwanted content,
• removing scripts from web pages,
• exempting URLs from blocking.
You can also use the Cerberian URL filtering to block unwanted URLs. For more
information, see “Configuring Cerberian URL filtering” on page 294.
