title: How to use multi-condition with if in use_backend (Haproxy)?
body: <p>I am using Haproxy to separate http and https with different domain setting,
  but domain limitation with http not working well. My setting as following.
  Any idea?</p>
  <pre><code>frontend ha_8080
    mode tcp
    bind *:8080
    tcp-request content accept if { req_ssl_hello_type 1 }
    tcp-request inspect-delay 100ms
    tcp-request content accept if HTTP
    acl is_using_ssl req.ssl_hello_type gt 0
  
    acl is_abc hdr_dom(host) -i abc.com
    use_backend http_server if !is_using_ssl is_abc  #it works and only works on abc.com,
    use_backend local_server1 if is_using_ssl is_abc #https will not working
    use_backend local_server1 if is_using_ssl        #it works, but I need it work only on abc.com
