Hi Jeffrey, The 'AND' key word is implicit and therefore you do not need to include it in your ACL's also the 'if' word is only needed once so for example your use_backend statement should look something like this:
use_backend bck1 if srv1_up srv1 has_ww_uri use_backend bck2 if srv2_up srv2 has_ww_uri Other than that your config file looks OK to me.
