    • A method and system for relaying a file object used in a gateway computer allowing the change of various parameters settings, dependent on particular networks, in a simple manner. The method and system further allowing reference of a file object referred to when a client computer was first connected to a certain network even when the client computer is then connected to another network in a simple manner. The method and system provides for relaying a file object in accordance with any of a plurality of control structures corresponding to a plurality of networks, respectively. The gateway computer includes storage for storing a file object. Each of the plurality control structures has an address of a representative gateway computer to which a client computer is connected. The method of relaying the file object includes the steps of receiving an event, when the event is a request for switching between the control structures, switching various parameters in accordance with that one of the control structures to which switching is requested, when the event is a request for getting the file object transmitted by the client computer, reading and relaying to the client computer the file object from either one of an upstream computer and the storage, and storing the relayed file object in the storage.
    • 一种用于中继在网关计算机中使用的文件对象的方法和系统,其允许以简单的方式依赖于特定网络来改变各种参数设置。 即使当客户端计算机以简单的方式连接到另一个网络时,该方法和系统还允许引用客户端计算机首先连接到某个网络时所引用的文件对象。 该方法和系统提供分别根据与多个网络对应的多个控制结构中的任何一个中继文件对象。 网关计算机包括用于存储文件对象的存储。 多个控制结构中的每一个具有与客户端计算机连接的代表性网关计算机的地址。 中继文件对象的方法包括以下步骤:当事件是在控制结构之间切换的请求时,接收事件,根据请求切换的控制结构中的一个切换各种参数,当事件为 请求获取由客户端计算机发送的文件对象,从上游计算机和存储器中的任一个读取和中继到客户端计算机的文件对象,并将中继的文件对象存储在存储器中。
