  • storing content from a content server as cached elements in a local cache on the mobile device;

    in response to receiving polling requests to contact the content server, retrieving the cached elements from the local cache to respond to the polling requests made at the mobile device;

    using state information associated with the cached elements to provide the cached elements as responses to the polling requests such that user experience is preserved;

    wherein, the polling requests are made by a mobile application installed on the mobile device;

    invalidating the cached elements in the local cache when new or changed data is detected at the content server;

    wherein, the state information includes an identification of a polling request whose corresponding cached element is to be invalidated; and

    enabling use of a radio on the mobile device to satisfy the polling requests when the cache elements have been invalidated.
