title: haproxy nested conditions for acl
body: <p>I need nested ACL conditions </p>
  
  <pre><code>acl route1 hdr_sub(host) -i abc.com hdr_sub(host) -i xyz.com 
  acl route2 path_beg /m1
  acl route3 path_beg /m2
  
  
  use backend back1 if route1 (route2 or route3)
  
  // essentially  
  route1 AND (route2 OR route3)
  </code></pre>
  
  <p>to match backends. What would be the correct HA code equivalent to this ?</p>
