title: How to fix Access-Control-Allow-Origin error from a remote site
body: <p>I'm trying to use the service at <a href="http://rate-exchange.appspot.com/currency" rel="nofollow">http://rate-exchange.appspot.com/currency</a>, but all I get is the the Access-Control-Allow-Origin error.</p>
  
  <p>Understanding this is a server problem, and that <a href="http://rate-exchange.appspot.com/currency" rel="nofollow">http://rate-exchange.appspot.com/currency</a> is not my service, I have no idea how to fix this problem.</p>
  
  <p>Using the service like this:</p>
  
  <pre><code>$.getJSON("http://rate-exchange.appspot.com/currency", { "from": Currency.From, "to": Currency.To }, function (result) {
      if (!result.err) {
          Currency.Rate = result.rate;
          $("#footer-output").text("All sales in " + Currency.To + " including VAT");
      }
      else {
          $("#footer-output").text("All sales in local currency including VAT");
      }
  });
  </code></pre>
  
  <p>Now trying to get this data directly in my browser is not a problem.  Is there anything I can do, or can this only be fixed on the server?</p>
