Description
Front end to the wccp client library. It is a stand alone program that speaks the client side of the
WCCP cache protocol.
It can be used instead of the built in WCCP feature in Traffic Server. This can be beneficial if you
have multiple programs running on the same computer that are relying on WCCP to redirect traffic from the
router to the computer.
Since it relies on the wccp library, traffic_wccp is only built if Traffic Server is configured with
--enable-wccp.
The overall Apache Traffic Server WCCP configuration documentation is at WCCPConfigurationLimitations
The current WCCP implementation associated with ATS only supports one cache client per service group per
router. The cache assignment logic currently assigns the current cache client to all buckets.

You need to run at least with the --service arguments. An example service definition file,
service-nogre-example.config, is included in the src/traffic_wccp directory. In this file you define your
MD5 security password (highly recommended), and you define your service groups. The details of the
service file are defined at WCCPServiceConfiguration.
