Do we need setTimeout for short polling?

Question

If I want to implement short polling like this:

function firstCall(){
   $.ajax({
     ...
     success: function(response){
         if (response.OK == "OK"){
              secondCall();
         }else{
            firstCall();
         }
     }
  });

}

Will this be enough? or do I really need to surround the firstCall() in else clause with setTimeout ?Thanks

I recommend you to use a little timeout, because now you are creating a lot of traffic to your server. Ajax is fast and success will be executed very often.

So I recommend you to use setTimeout or setInterval instead!
