Abstract

A client terminal obtains the environment information thereof and informs a Web server of the environment information with a reduced processing load, so as to receive services presented by the Web server. The client terminal creates the environment information corresponding to a request transmitted from the Web server and stores the environment information in a storage device. In the case where environment information is subsequently required, the client terminal may use the existing environment information, update part of the environment information, or add new environment information to the existing environment information with reference to the stored environment information instead of creating new environment information.

Claims

1. An information processing apparatus that can use contents provided by a Web server through a browser software program in the information processing apparatus, the information processing apparatus comprising:

a creating unit for creating/updating environment information according to an environment-information request transmitted from the Web server;

a storing unit for storing the created/updated environment information in a storage device; and

a transmission unit for transmitting the created/updated environment information to the Web server via a network,

wherein, in a case where the environment-information request is transmitted from the Web server after the creating unit has created environment information, the creating unit updates the environment information with reference to the environment information stored in the storage device, and

wherein the contents presented by the Web server is determined according to the environment information.

2. The information processing apparatus according to claim 1, wherein the environment information is information about at least one peripheral device connected to the information processing apparatus and an utilization program for utilizing the at least one peripheral device, the information processing apparatus further comprising:

an obtaining unit for obtaining information about the peripheral device and the utilization program,

wherein, in a case where the creating unit compares the information obtained by the obtaining unit to the environment information stored in the storage device, and the information obtained by the obtaining unit and the environment information stored in the storage device are equivalent, the creating unit stops creating/updating the environment information.

3. The information processing apparatus according to claim 1, wherein the environment information is information about at least one peripheral device connected to the information processing apparatus and a utilization program for utilizing the at least one peripheral device, the information processing apparatus further comprising:

an obtaining unit for obtaining information about the peripheral device and the utilization program,

wherein, in a case where the creating unit compares the information obtained by the obtaining unit and the environment information stored in the storage device, and peripheral-device information of the information obtained by the obtaining unit agrees with peripheral-device information of the environment information stored in the storage device and utilization-program information of the information obtained by the obtaining unit is different from utilization-program information of the environment information stored in the storage device, the creating unit updates the environment information by updating the utilization-program information of the environment information stored in the storage device.

4. The information processing apparatus according to claim 1, wherein the environment information is information about at least one printer connected to the information processing apparatus and a printer driver program for utilizing the at least one printer, and wherein the Web server presents print services via the network.

5. The information processing apparatus according to claim 1, wherein the environment information is information about at least one printer connected to the information processing apparatus and a printer driver program for utilizing the at least one printer, the information processing apparatus further comprising:

a reception unit for receiving information about a model name of the printer transmitted from the Web server,

wherein the creating unit creates/updates the environment information based on information about a printer corresponding to the printer-model information transmitted from the Web server and the information about the printer driver program for utilizing the at least one printer.

6. A method for controlling an information processing apparatus that can use contents presented by a Web server through a browser software program in the information processing apparatus, the controlling method comprising steps of:

creating/updating environment information according to an environment-information request transmitted from the Web server;

storing the created/updated environment information in a storage device; and

transmitting the created/updated environment information to the Web server via a network,

wherein, in a case where the environment-information request is transmitted from the Web server after environment information has been created and stored in the storage device, the environment information is updated with reference to the environment information stored in the storage device, and

wherein the contents presented by the Web server is determined according to the environment information.

7. A program for making a computer system perform a method for controlling an information processing apparatus that can use contents presented by a Web server through a browser software program in the information processing apparatus, the program comprising steps of:

creating/updating environment information according to an environment-information request transmitted from the Web server;

storing the created/updated environment information in a storage device; and

transmitting the created/updated environment information to the Web server via a network,

wherein, in a case where the environment-information request is transmitted from the Web server after environment information has been created and stored in the storage device, the environment information is updated with reference to the environment information stored in the storage device, and

wherein the contents presented by the Web server is determined according to the environment information.
