NAME

       traffic_wccp - Traffic Server WCCP client

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 WCCP Configuration

OPTIONS

       --address IP address to bind.

       --router Bootstrap IP address for routers.

       --service Path to service group definitions.

       --debug Print debugging information.

       --daemon Run as daemon.

       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 WCCP Service Configuration.

LIMITATIONS

       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.
