    Hi Shkasjon,

    The addthis_widget.js is already cached. We use an 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?
