Content Filtering blocks or allows HTTP access to websites containing specific
keywords or domains. It controls access to certain Internet sites based on analysis
of its content (domain or URL keyword), rather than its source or other criteria. It is
most widely used on the Internet to filter web access.
Refer to the following topics:
• Configuring Content Filtering Policy Profiles, page 233
• Configuring Website Access Control List, page 234
• Mapping Content Filtering Policy Profiles to Zones, page 235
• Configuring Advanced Content Filtering Settings, page 236
Enabling Firewall Content Filtering will disable Web URL Filtering. Enabling Web
URL Filtering will disable Firewall Content Filtering.

allowed.
