<div>Should I change the probe request "HEAD /" to something else?<br>
Is there any way to define special port and whenever it is accessable even with authentication erro (error 400) it consider backend healthy?

Hi,<br>
I want to adjust health check on my varnish backends, But I dont know how can I know they are healthy or not
<br>
because the nodes are up and running and even service is up but varnish does'nt work for all requests (just third of them are responding till I restart it (It happens sometimes)).

<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
How can I check this?<br>
