Ajax Synchronous Callbacks

Question

I have pageTest.html in a local folder, is service.ashx called on this page? i = ... (which return param pass incremented +1) followed by Ajax code:

.
.
getIncr: function(parameters, success){
       $.ajax({
               async: false, 
               type: methodType,
               url: getTarget,
               data: "n="+parameters,
               dataType:"jsonp",
               success: success
             });
    }
.
.

The html page calls this function for time m (with script ..):

  .    
  var start = function(){
  .
  .
  var val = 0;
  .      
  .
  for(i=0; i<m; i++)
  {
      Foo.getIncr(val, function(returned_n){
          val = returned_n;
      });

  }

};

When the page loads, calls are made in "Asynchronous mode", but I set " async: false " to Ajax. I read about this problem and found the reason, that is, Ajax cannot synchronize the call from page.html to service.ashx if there is one in another domain. Is there a solution for making a Synch call in page.html to this service.ashx (in another domain)?
