The address of a secure website has the form: https://www.example.com. Web | Web Policies | Scanning Policies | HTTPS web categorization To determine which sites to block, the appliance refers to its lists of denied URLs. HTTPS filtering might not work as expected. Because the URL (website address) is encrypted, the appliance must resolve the IP address into a name, then match that name against a list of denied URLs. A single IP address often serves many websites. For example, suppose www.example.com and www.mcafee.com resolve to 123.123.123.123. However, the IP address, 123.123.123.123 resolves only to www.mcafee.com. If the list of denied URLs includes www.example.com but does not include www.mcafee.com, the appliance cannot block a secure HTTP connection to 123.123.123.123.
