Abstract: A client computing device accessing a cloud computing system identifies applications that a user can use to access a cloud computing service. The client computing device receives an account list of applications associated with a user account on the cloud computing system, and identifies at least one of a characteristic of the client computing device and a local list of applications installed on the client computing device. The client computing device generates an availability list of applications based on the account list and the identified local list and device characteristics.

Abstract: The origin server which supplies content to a client mobile web-browsing device cin tag content (e.g. a homepage) as ‘persistent’ by applying a special definition to that content, The content and accompanying definitions are then sent to the device over the cellular network. The browser on the device is programmed to recognise this definition and to set an appropriate flag against that content; the flag defines how the device uses the content—in particular, defining that the device will not discard that content front memory even when flushing the cache to free up disc space. Hence, flagged home pages can become persistent since they are not discarded from memory; as such they can reliably be viewed even when the device is out of cellular coverage and the device has freed up disc space.
