title: jQuery normally cached when loaded from Google CDN?
body: <p>I know one of the benefits of linking jQuery from Google's CDN is that as other sites do the same, the file may be cached on the user's computer and not have to be downloaded again. How often will this be the case? </p>
  
  <p>If I link to the latest version of jQuery for a particular site im unlikely to bother going back and changing the link each time a new version is out.  </p>
  
  <p>Thanks </p>
