Loadbalancing with 301 / 302

[Enno van Amerongen]

Hi,

First of all, if you get an error, tell us what it is.

Second, you seem to have copypasted the healthchecks directly from the
docs, not sure if it works or if its a typo in the docs, but I'd say:
.timeout = 1s (without the space)

Third, your vcl_recv is wrong, try:

sub vcl_recv {
    set req.backend = baz;
    return (lookup);
}

good luck!
