title: Varnish backend host directly in vcl_recv?
body: <p>Can I mention backend host directly in vcl_recv?</p>
  
  <pre><code>   sub vcl_recv{
         if (req.http.host=="www.yourdomain.com.a-free-cdn.com") {
             set req.http.host = "www.yourdomain.com";
             set req.backend.host = "www.yourdomain.com";
         }
     }
  </code></pre>
  
  <p>If this is not possible, is there an alternate way to do that? Actually, I don't know in advance anything about back-ends.</p>
