Abstract

In an Internet home page data acquisition method, an access list held by a client is transferred to a cache URL address storage server. Home page data is acquired by a cache server on the basis of the transferred access list. The acquired home page data is transferred from the cache server to the client upon completion of acquisition of the home page data.

Claims

1. An Internet home page data acquisition method in a network system comprising:

a client device acquiring and displaying home page data,

a cache URL address storage server storing an access list of a URL address transferred from the client device as a cyclic list,

a cache server acquiring and temporarily storing the home page data on the basis of the cyclic list stored in the cache URL address storage server, and

a cache server for collecting home page data on the basis of the cyclic list stored in the cache URL address storage server to store temporarily the home page data, the method comprising the steps of;

providing the client device with a server storage cyclic folder and a client storage cyclic folder;

storing an access list of a URL address which requests to leave a cycle to the cache server in the server storage cyclic folder of the client device;

transferring the access list held in the server storage cyclic folder of the client device to the cache URL address storage server as the cyclic list;

acquiring home page data by the cache server on the basis of the cyclic list transferred to the cache URL address storage server; and

making the client device pick up the home page data collected by said cache server, the client device collecting the home page data on the basis of the access list stored in the client storage cyclic folder of the client device.

2. A method according to claim 1, wherein

said client includes a server storage cyclic folder for storing an access list to be transferred to said cache URL address storage server, and

the step of transferring the access list comprises transferring the access list retained in said server storage cyclic folder to said cache URL address storage server.

3. A method according to claim 1, wherein the step of transferring the home page data comprises the steps of:

causing said cache server to connect a line to said client when acquisition of home page data is completed; and

transferring the acquired home page data from said cache server to said client after the line is connected.

4. A method according to claim 1, wherein the step of transferring the home page data comprises the steps of:

causing said client to connect a line to said cache server when acquisition of home page data is completed; and

transferring the acquired home page data from said cache server to said client after the line is connected.

5. A method according to claim 4, wherein the step of connecting the line comprises the step of periodically connecting the line to said cache server.

6. A method according to claim 4, wherein

the method further comprises the step of causing said cache server to notify said client of an acquisition end time when the access list is transferred, and

the step of connecting the line comprises the step of connecting the line to said cache server at the notified acquisition end time.

9. The method according to claim 1, wherein the client connects the line to the cache server when acquisition of home page data is completed.

10. The method according to claim 9, wherein the step of connecting the line comprises the step of periodically connecting the line to the cache server.

11. A method according to claim 9, wherein the method further comprises the steps of:

causing the cache server to notify the client of an acquisition end time when the access list is transferred, and

the step of connecting the line comprises the step of connecting the line to the cache server at the notified acquisition end time.

7. A method for acquiring an Internet home page, the method comprising:

connecting a line between a client and a cache URL address storage server;

transferring an access list from the client to the cache URL address storage server, the access list comprising URL addresses that the client wishes to receive;

disconnecting the line between the client and the cache URL address storage server;

acquiring home page data at a cache server on the basis of the URL addresses in the transferred access list;

connecting a line between the client and the cache server upon completing the acquisition of the home page data; and

transferring the acquired home page data from the cache server to the client, wherein

the client includes a server storage cyclic folder for storing an access list to be transferred to the cache URL address storage server, and

the step of transferring the access list comprises transferring the access list retained in the server storage cyclic folder to the cache URL address storage server.

8. The method according to claim 7, wherein the cache server connects the line to the client when acquisition of home page data is completed.
