When requests are routed to Content Gateway in transparent proxy mode, the records.config variable proxy.config.arm.always_query_dest can be used to configure Content Gateway to ignore host headers and always ask for the IP address of the origin server. When this variable is enabled, Content Gateway obtains the origin server's IP address from the inbound packet rather than trying to resolve the destination host name with a DNS lookup. As a result, logged URLs contain only IP addresses, not host names. To log domain names, you must disable proxy.config.arm.always_query_dest (set it to 0).
