Abstract

A network server, a transmission control method and a recording medium are provided for controlling an access to an information resource easily and flexibly. A WWW server has transmission control means for controlling transmission of a hypertext. The hypertext includes an access permission information concerning permission of the access to the hypertext. The transmission control means control the transmission of the hypertext to a terminal device in accordance with the access permission information when the terminal device requests for the access to the hypertext.

Claims

1. A network server comprising transmission control means for controlling transmission of a hypertext, the hypertext including access permission information that is information concerning permission of an access to the hypertext, the transmission control means controlling the transmission of the hypertext to a client in accordance with the access permission information when the client requests for the access to the hypertext.

2. The network server according to claim 1, wherein when transmitting the hypertext, the transmission control means generate a hypertext in which the access permission information is deleted and send the same.

3. A method for controlling transmission of a hypertext, the method being used in a network system including a network server for transmitting the hypertext and a client capable of accessing to the network server, the hypertext including a description of access permission information that is information concerning permission of an access to the hypertext, the method comprising the steps of:

deciding whether the hypertext should be transmitted to the client in accordance with the access permission information of the hypertext when the client requests the network server for the access to the hypertext; and

transmitting the hypertext when it is decided that the hypertext should be transmitted.

4. The method according to claim 3, wherein when transmitting the hypertext, a hypertext in which the access permission information is deleted is generated and is transmitted.

5. A recording medium that can be read by a computer including transmission control means for controlling transmission of a hypertext, the medium storing a hypertext in which access permission information that is information concerning permission of an access is described.
