A significant number of mobile applications employ HTTP as their primary network protocol, as the underlying remote services oftentimes are based on World Wide Web (WWW) technology stacks. Similarly, in recent years, mobile devices have emerged as the primary means to access the WWW. We present cacheConnect, a portable mobile proxy implementation that enables aggregation and content optimization on mobile devices, rather than the commonplace proxy operations performed in the cloud. Based on this additional local caching tier that negotiates between remote data servers (for browsing or otherwise) and local applications, we enable new means of content provisioning and application-level transparent optimizations. Our demonstration highlights the operations of our solution on Android mobile devices.
