1. A method of training a server for content delivery based on communication of state information from a mobile device browser, said method comprising: providing a control channel between the server and mobile device browser; transmitting over said control channel a plurality of request messages from the mobile device browser to the server for Web pages, each of said messages indicating browsing-related state data; implementing a heuristic algorithm within said server to detect and learn patterns of said request messages, wherein implementing said heuristic algorithm includes building an internal statistical model of said patterns of request messages to determine a set of URLs that said mobile device browser is most likely to request next; pre-fetching at least hypertext content of Web pages that said server has learned will likely be requested if said statistical model indicates that probability of next one of said web pages being requested next exceeds a first threshold, and otherwise awaiting a further one of said request messages indicating a specific requested URL and adjusting the statistical model in response thereto; and embedding said at least hypertext content in response codes within response messages over said control channel from said server to said mobile device browser.
