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 for transmitting a hypertext to a client, comprising:

a storage portion storing a first hypertext containing access permission information that is information concerning whether an access of the first hypertext is permitted;

a request receiving portion receiving a request for the first hypertext from the client;

a determining portion determining whether the first hypertext concerning the request can be transmitted in accordance with the access permission information contained in the first hypertext;

a hypertext generating portion generating a second hypertext by removing the access permission information from the first hypertext when it is determined that the first hypertext concerning the request can be transmitted; and

a hypertext transmitting portion transmitting the generated second hypertext to the client that made the request.

2. The network server according to claim 1, wherein

the access permission information in the first hypertext indicates a client that is permitted to get access to the first hypertext, a client that is not permitted to get access to the same and a password, and

the determining portion determines that the first hypertext can be transmitted if the access permission information contained in the first hypertext concerning the request indicates that the client that made the request is permitted to get access, determines that the first hypertext cannot be transmitted if the access permission information indicates that the client is refused to get access, and determines the first hypertext can be transmitted under the condition that a password entered by the client matches a password indicated in access permission information if the access permission information does not contain information about whether or not the client can get access.

3. A method for transmitting a hypertext to a client, the method comprising:

storing a first hypertext containing access permission information that is information concerning whether an access of the first hypertext is permitted;

receiving a request for the first hypertext from the client;

determining whether the first hypertext concerning the request can be transmitted in accordance with the access permission information contained in the first hypertext;

generating a second hypertext by removing the access permission information from the first hypertext when it is determined that the first hypertext concerning the request can be transmitted; and

transmitting the generated second hypertext to the client that made the request.

4. The method according to claim 3, wherein the access permission information in the first hypertext indicates a client that is permitted to get access to the first hypertext, a client that is not permitted to get access to the same and a password, and

the determining further comprises:

determining that the first hypertext can be transmitted if the access permission information contained in the first hypertext concerning the request indicated that the client that made the request is permitted to get access,

determining that the first hypertext cannot be transmitted if the access permission information indicates that the client is refused to get access, and

determining that the first hypertext can be transmitted under the condition that a password entered by the client matches a password indicated in access permission information if the access permission information does not contain information about whether the client can get access.

5. A computer-readable storage storing a computer-readable program which controls a computer system to in transmitting a hypertext to a client, by:

storing a first hypertext containing access permission information that is information concerning whether an access of the first hypertext is permitted;

receiving a request for the first hypertext from the client;

determining whether the first hypertext concerning the request can be transmitted in accordance with the access permission information contained in the first hypertext;

generating a second hypertext by removing the access permission information from the first hypertext when it is determined that the first hypertext concerning the request can be transmitted; and

transmitting the generated second hypertext to the client that made the request.

6. The computer-readable storage storing a computer-readable program which controls a computer system in transmitting a hypertext to a client according to claim 5, wherein the access permission information in the first hypertext indicates a client that is permitted to get access to the first hypertext, a client that is not permitted to get access to the same and a password, and

the determining further comprises:

determining that the first hypertext can be transmitted if the access permission information contained in the first hypertext concerning the request indicated that the client that made the request is permitted to get access,

determining that the first hypertext cannot be transmitted if the access permission information indicates that the client is refused to get access, and

determining that the first hypertext can be transmitted under the condition that a password entered by the client matches a password indicated in access permission information if the access permission information does not contain information about whether the client can get access.
