Help | Content Gateway | Version 7.7.3


Configuration Variable	Data Type	Default Value	Description
proxy.config.dns. search_default_domains	INT	1	Enables (1) or disables (0) local domain expansion so that Content Gateway can attempt to resolve unqualified hostnames by expanding to the local domain; for example, if a client makes a request to an unqualified host named host_x, and if the Content Gateway local domain is y.com, Content Gateway expands the hostname to host_x.y.com.
proxy.config.dns. splitDNS.enabled	INT	0	Enables (1) or disables (0) DNS server selection. When enabled, Content Gateway refers to the splitdns.config file for the selection specification. See Using the Split DNS option
proxy.config.dns. splitdns.def_domain	STRING	NULL	Specifies the default domain for split DNS requests. This value is appended automatically to the hostname if it does not include a domain before split DNS determines which DNS server to use.
proxy.config.dns. url_expansions	STRING	NULL	Specifies a list of hostname extensions that are automatically added to the hostname after a failed lookup; for example, if you want Content Gateway to add the hostname extension .org, specify org as the value for this variable (Content Gateway automatically adds the dot (.).) Note: If the variable proxy.config.http.enable_url_ expandomatic is set to 1 (the default value), you do not have to add www. and .com to this list; Content Gateway tries www. and .com automatically after trying the values you specify.
proxy.config.dns. lookup_timeout	INT	20	Specifies the DNS lookup timeout duration in seconds. When the timeout period expires, the lookup attempt is terminated.
proxy.config.dns.retries	INT	5	Specifies the number of times a DNS lookup is retried before giving up.
proxy.config.dns. prefer_ipv4	INT	1	When a name resolves to both IPv4 and IPv6 addresses, specifies the prefered address type .
proxy.config.ipv6. ipv6_enabled	INT	0	Specifies to enable (1) or disable (0) support for IPv6.
