This used to be a common experience but not many websites do it anymore. If you're on a website and click an external link, the website would open the external link with a navigation or controls bar at the top of the browser and the external link in a frame. This keeps the user under the original domain without navigating away. The bar would have buttons or controls for the user. LinkedIn used to do it, Ask.com and I think facebook at some point.
Does anyone know of websites still using this approach? I'm trying to find some examples.
