<div class="im"><br>

</div>I had the same need some time ago, and solved it by simply switching<br>
backends when the main ones are in an "unhealthy" state:<br>
<br>
director cluster round-robin {<br>
{ .backend = {<br>
...<br>
.probe = { # required to let req.backend.healthy work<br>
...<br>
}<br>
}<br>
}<br>
...<br>
}<br>
<br>
backend sorryserver {<br>
...<br>
}<br>
<br>
sub vcl_recv {<br>
<br>
set req.backend = cluster;<br>
<br>
if (!req.backend.healthy) {<br>
set req.backend = sorryserver;<br>
pass;<br>
}<br>
}<br>
<br>
I hope this helps !<br>
