Prefetching and pre-rendering links in the background
IE11 can prefetch and pre-render HTML5 links. This is a feature that can be implemented by a web developer to speed up the way pages are delivered to the browser. For example, while you are reading the first page of an article, the link that you would click leading to the second page where the article continues is silently loaded and rendered by IE11 in anticipation that you will click the link.
