Examples
The following rule configures a parent cache hierarchy consisting of Content Gateway (which is the child) and two parents, p1.x.com and p2.x.com. The proxy forwards the requests it cannot serve to the parent servers p1.x.com and p2.x.com in a round-robin fashion because round_robin=true.
dest_domain=. method=get parent="p1.x.com:8080; p2.y. com:8080" round_robin=true
The following rule configures Content Gateway to route all requests containing the regular expression politics and the path /viewpoint directly to the origin server (bypassing any parent hierarchies):
url_regex=politics prefix=/viewpoint go_direct=true
The following rule is a typical destination bypass rule:
dest_domain=example.com go_direct=true
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).
