Handheld client framework system

摘要

A handheld client framework system provides a server proxy client that services client requests for network accessible information and determines the server that is most appropriate to supply the requested information and sends information request packets to that server across the Internet and/or intranet. Server responses to information requests are received by the server proxy client. The server proxy client separates the response information into the appropriate data components. Data components are sent to the appropriate client. Presentation and logic components are temporarily stored in a one-behind cache on the client. A client will continue to use the presentation and logic components already installed or in the one-behind cache to service the current user request. Any updates sent by the server proxy client and stored in the one-behind cache are retrieved by the client upon subsequent use by the user. The state of the client is saved by the server proxy client so that the client is not dropped when a user, for example, changes from a wired connection to a wireless connection. The invention includes a scripting language that supplies the logic component of the client and gives the client unlimited flexibility by allowing the host to modify the client's behavior or add new features at any time.
