varnish redundancy

| Is there an advantage in using a director here instead of the following?
| 
| sub vcl_recv {
|     set req.backend = haproxy01;
|     if (!req.backend.healthy) {
|         set req.backend = haproxy02;
|     }

If haproxy01 is marked as healthy, but refuses the connection for
whatever reason, you'll end up in vcl_error here.  A director will give
you a connection to the other one.
