Abstract: A mail gateway generates an identifier for each attached file included in the e-mail addressed to a user and held in a mail server, and notifies a mail terminal belonging to the user of a list of generated IDs. When the user selects attached files that the user wants to attach to the e-mail from the list of IDs that is notified from the mail gateway, the mail gateway constructs e-mail including the selected attached files and the mail server transmits the constructed e-mail to addresses of the receivers of the e-mail.

Abstract: The technology that is capable of causing operation keys of a mobile terminal to flexibly deal with external data such as a new program, or the like, and also improving an operability of the mobile terminal in handling the external data can be provided. In the network system 300, a mobile terminal 100 transmits transmitted information containing operation information, which corresponds to an amount of physical operation in a user's operation applied to an operation inputting portion 121, 119, to a server 200, and then the server 200 generates information containing the operation information and then transmits the information to the mobile terminal 100 via a network 400.

Abstract: A proxy server apparatus receives a resource obtainment request from a client terminal apparatus, creates, from the received resource obtainment request, divisional get requests that specify resource obtainment ranges, and sends the divisional get requests to a web server apparatus. The proxy server apparatus includes a control unit and a management unit. The control unit creates the divisional get requests by referring to margin times and wait times managed for each request by the management unit.

Abstract: Provided is an appliance control system and method for remotely controlling various types of electrical home appliances using a mobile communications terminal, and a home gateway. To operate the electrical home appliances which vary in manufacturer and type, a database 71 in a database center 7 stores each corresponding appliance control program. In a household area 3, the electrical home appliance(s) 4 are connected to a home gateway 6 via a household network 5. The home gateway 6 collectively controls information about the storage locations of the appliance control programs on the database 71 together with various types of information about the electrical home appliances 4. A mobile communications terminal 2 refers to the home gateway 6 so as to acquire from the database 71 only the appliance control program of any electrical home appliance 4 which a user desires to operate.
