    • A method and system using directive script in a web intermediary proxy machine that provides the function of a transcoder. The intermediary machine's transcoders are controlled by directive script that directs the order and properties of transcoder operations executed on one or more transcoders in the intermediary machine. These directive scripts are stored in an on-the-fly modifiable directive database accessible to the web intermediary proxy machine. The user's client machine browser passes an HTTP request to the web intermediary machine, which passes the HTTP request to a web content server, which returns an HTML response back to the web intermediary machine. This HTML response is sent to at least one transcoder that resides in or is at least accessible to the intermediary proxy machine. The transcoder identifies the type of device being used by the client from the HTTP request. The user's preference transcoding settings are retrieved in the form of directives from a directive script, preferably in XML format, retrieved from a settings database, and applied to the transcoders. The tailored transcoded response is then sent back to the user's client machine.
    • 一种在web中介代理机中使用指令脚本的方法和系统,其提供代码转换器的功能。 中介机器的代码转换器通过指令脚本进行控制,该指令脚本指导在中间机器中的一个或多个代码转换器上执行的代码转换器操作的顺序和属性。 这些指令脚本存储在Web中介代理机可访问的即时可修改指令数据库中。 用户的客户端机器浏览器将HTTP请求传递给web中介机器,该中介机器将HTTP请求传递给Web内容服务器,Web内容服务器将HTML响应返回给Web中介机器。 该HTML响应被发送到驻留在中介代理机器中或至少可访问的至少一个代码转换器。 代码转换器从HTTP请求中识别客户端正在使用的设备类型。 以指令的形式从用户设置数据库检索的指令脚本(最好是XML格式)中检索用户的偏好转码设置,并将其应用于代码转换器。 然后将定制的代码转换的响应发送回用户的客户端机器。
