Important  After you modify this file, run content_line -x from the Content Gateway bin directory (/opt/WCG/bin) to apply the changes. When you apply the changes to a node in a cluster, Content Gateway applies the changes to all nodes in the cluster.

Primary Destination	Allowed Value
dest_domain	A requested domain name
dest_host	A requested hostname
dest_ip	A requested IP address or range of IP addresses separated by a dash (-).
url_regex	A regular expression to be found in a URL

Secondary Specifier	Allowed Value
time	A time range, such as 08:00-14:00, during which the parent cache is used to serve requests
prefix	A prefix in the path part of a URL
suffix	A file suffix in the URL
src_ip	A client IP address.
port	A requested URL port
scheme	A request URL protocol; one of the following: HTTP FTP
method	A request URL method; one of the following: get post put trace
user_agent	A request header User-Agent value.

Action	Allowed Value
parent	An ordered list of parent servers. If the request cannot be handled by the last parent server in the list, it will be routed to the origin server. You can specify either a hostname or an IP address. You must specify the port number.
round_robin	One of the following values: true - Content Gateway goes through the parent cache list in a round-robin based on client IP address. strict - Content Gateway machines serve requests strictly in turn. For example, machine proxy1 serves the first request, proxy2 serves the second request, and so on. false - round-robin selection does not occur.
go_direct	One of the following values: true - requests bypass parent hierarchies and go directly to the origin server. false - requests do not bypass parent hierarchies.

Important  Every line in the parent.config file must contain either a parent= or go_direct= directive. A bypass rule that includes parent= and go_direct=true, causes the specified dest_domain to be sent to the parent while all other domains are bypassed (the opposite of the usual intended action).
