Appendix D
The following tables lists the possible actions and their allowed values:
Action
parent
round_robin
go_direct

Example

The following rule sets up a parent cache hierarchy consisting of the Traffic Server (which is the child) and
two parents, and
p1
parent server,
p1.x.com
p2.y.com. Because round_robin=true
dest_domain=. method=get parent="p1.x.com:8080; p2.y.com:8080" round_robin=true
The following rule tells the Traffic Server to route all requests containing the regular expression
and the path
/viewpoint
url_regex=politics prefix=/viewpoint go_direct=true
Every line in the
parent.config
A parent cache entry in the Parent Caching section of the Routing page, described on page 53, is entered as
the bottom line in the

partition.config

The
partition.config
creating cache partitions of different sizes for specific protocols. You can further configure these partitions to
store data from certain origin servers and/or domains in the
page 166).
For step by step instructions on partitioning the cache, refer to
IMPORTANT
You must stop Traffic Server before you change the cache partition size and protocol assignment.
Allowed Value
Enter an ordered list of parent proxies. If the request cannot be handled by the
last parent server in the list, it will be routed to the origin server.
true
Enter true if you want the Traffic Server to go through the parent cache list in a
round robin.
strict
Enter strict if you want Traffic Server machines to serve requests strictly in
turn. For example, machine ts-sun8 serves the first request, ts-sun9 serves the
second request, and so on.
false
Enter false if you do not want round robin selection to occur.
true
Enter true if you want requests to bypass parent hierarchies and go directly to
the origin server.
false
Enter false if you do not want requests to bypass parent hierarchies.
