<p dir="ltr">OK, so your vcl is wrong and the round-robin is not what you want.</p>
<p dir="ltr">Get rid of you vcl_init (wrong in your case) and vcl_hash (this is the default one, no need for it, at least for now), and use something like:</p>
<p dir="ltr">sub vcl_recv {<br>
if (req.http.host == "<a href="http://foo.com">foo.com</a>") {<br>
set req.backend_hint == s1;<br>
} else {<br>
set req.backend_hint == s2;<br>
}<br>
}</p>
