title: How to change $.ajax() default settings?
body: <p>How can I modify the default values of options for the <a href="http://api.jquery.com/jQuery.ajax/" rel="noreferrer"><code>$.ajax()</code></a> function?</p>
  
  <p>Ideally to do something similar to:  </p>
  
  <pre><code>//set ajax async to false
  $(someSelector).load(url, data, function(){});
  //set ajax async to true
  </code></pre>
  
  <p>to allow me to carry out <code>.post()</code> synchronously.</p>
