title: Force Play Framework to listen on localhost only
body: <p>How can you force the Play Framework listen on localhost only<br>
  i would like that the play will listen on the localhsot:9000 and not on 0.0.0.0:9000<br>
  so it won't be accessible to  external IP<br>
  i tried to use<br>
  http.address=127.0.0.1
  on the application.conf , but it didn't seem to make any change.<br>
  using netstat i saw that play use 0.0.0.0:9000</p>
  
  <p>Thanks</p>
