title: Why is jQuery appending stuff to the end of my AJax requests?
body: <p>I have this piece of code:</p>
  
  <pre><code>$.getJSON('http://domai.nr/api/json/search?q='+encodeURI(d.val())+'&amp;callback=?','',function(data){...});
  </code></pre>
  
  <p>But I'm seeing this in my Google Chrome console:</p>
  
  <pre><code>GET http://domai.nr/api/json/search?q=google.com&amp;callback=jQuery162020250764419324696_1323616418227&amp;_=1323616456577 500 (Internal Server Error)
  </code></pre>
