Some of the newer CDN technologies can address the logic level in a number of innovative ways. First, they can more intelligently cache information close to end users with mobile devices, and use the location as a cache-key. So, for example, a weather site can, with this type of logic, cache appropriate detailed weather information for a user in the CDN based on their initial GPS contact point. This weather data can be later served to other users located a few blocks away, eliminating the need for additional round trips.
