title: Cross-Origin AJAX request
body: <p>Sometimes the rules make no sense to me.</p>
  
  <p>How do people make an ajax request to a google api or something like that? I mean does everything have to be cross-origin? It seems stupid... why can't I make a nonblocking ajax get request to google..</p>
  
  <p>I've heard you can use jsonp-- but in that case the server has to support that format. I want a way to make async ajax get requests to cross-origin pages.</p>
