Answer 1

You can access parent window using 'window.opener', so, write something like the following in the child window:

onunload="window.opener.location.reload();"

or use this

<script>
    window.onunload = refreshParent;
    function refreshParent() {
    var retVal = confirm("Are you sure ?");
           if( retVal == true ){
            window.opener.location.reload();
          else
            return false;

    }
</script>
