synchronous ajax is not working: 

        var rslt = false;

            $.ajax({
                async: false,
                url: url,
                dataType: "json",
                success: function(data) {                      
                     rslt = true;                      
                }                      
                });


            document.write(rslt);

rslt still displays as false.

I am out of ideas...

    Maybe you're getting an ERROR. You don't have any error detection here – Ian Aug 21 '13 at 21:04

  • if you weren't using `document.write`, you wouldn't feel the need to use synchronous AJAX. The disease is bad, but so is the cure. – John Dvorak Aug 21 '13 at 21:29
  • i don't think you should get callbacks with sync... – dandavis Aug 21 '13 at 21:34

You could inform if it's a GET or a POST, as you're not passing anything, I think its a get, sou set the type to 'GET'

This should work:

var rslt = false;

            $.ajax({
                async: false,
                type: 'GET',
                dataType: 'json',
                url: url,
                success: function(data) {                      
                     rslt = true;                      
                }                      
            });


document.write(rslt);
