title: jQuery jsonp caching, is there a way to change timestamp url key?
body: <p>Hello I'm creating a jsonp api and I'm using <code>cache = false</code> in my <code>$.ajax()</code> settings. However my server requires a specific prefix in front of every url <code>GET</code> parameter.</p>
  
  <p>ex. <code>http://www.domain.com/test?_prefix_age=29</code> </p>
  
  <p>I have accomplished such a thing but I cant find a way to add my prefix in the caching timestamp parameter <code>_:{TIMESTAMP}</code></p>
  
  <p>From jQuery <code>$.ajax()</code> docs:</p>
  
  <blockquote>
    <p>cache (default: true, false for dataType 'script' and 'jsonp') Type:
    Boolean If set to false, it will force requested pages not to be
    cached by the browser. Note: Setting cache to false will only work
    correctly with HEAD and GET requests. It works by appending
    "_={timestamp}" to the GET parameters. The parameter is not needed for
    other types of requests, except in IE8 when a POST is made to a URL
    that has already been requested by a GET.</p>
  </blockquote>
  
  <p>Is there any way I could add the prefix infront of the timestamp parameter without messing up jQuery internally ?</p>
