Understanding cross domain difference for AJAX POST request

Question

I have written a piece of jQuery code in http://example.com .

The code looks like this:

$.post('http://example.com:3000/service',params,function(data){});

This code works in chrome and firefox but not in IE . Is my request crossbrowser?

Thanks in advance
