 * Hi Shkasjon,
 * The addthis_widget.js is already cached. We use an [ETag](https://en.wikipedia.org/wiki/HTTP_ETag)
   to tell the browser how to cache it. Some page performance sites are looking 
   for the older style caching headers so it may appear that there is no caching
   on that URL to them. That URL is also backed by our CDN, so there are also locality
   improvements as well.
 * Is there a specific issue you are having?
 * -Brad
