ACLsΒΆ

You create a named access control list with the acl keyword. You can match the IP address of the client against an ACL with the match operator.:

# Who is allowed to purge....
acl local {
    "localhost";
    "192.168.1.0"/24; /* and everyone on the local network */
    ! "192.168.1.23"; /* except for the dialin router */
}

sub vcl_recv {
  if (req.method == "PURGE") {
    if (client.ip ~ local) {
       return(purge);
    } else {
       return(synth(403, "Access denied."));
    }
  }
}
