title: jQuery getScript function adds search parameter and a 404 error is thrown
body: <p>I use <a href="http://api.jquery.com/jQuery.getScript/" rel="nofollow"><code>getScript()</code> jQuery function</a> to import Bootstrap 3 js file:</p>
  
  <pre><code>$.getScript("//netdna.bootstrapcdn.com/bootstrap/3.0.0/js/bootstrap.min.js");
  </code></pre>
  
  <p>I cannot understand why jQuery adds a search parameter to the url and the result is a 404 - Not found error:</p>
  
  <pre><code>GET http://netdna[...]/3.0.0/js/bootstrap.min.js?_=1379832218975 404 (Not Found) 
  // Why does this parameter appear? -------------^^^^^^^^^^^^^^^^
  </code></pre>
  
  <p>I created a <a href="http://jsfiddle.net/zBjca/" rel="nofollow"><strong>JSFIDDLE</strong></a> that demonstrates this.</p>
  
  <p>How can I fix it?</p>
