DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a WWW server and a WWW used for providing information on the Internet.
The present invention relates to a WWW update notification system of a client side technology for browsing a server.

[0002]

2. Description of the Related Art In recent years, entry into the Internet network has increased dramatically. When trying to get information on the Internet, first from your personal computer to the contracted provider who is the gateway to the Internet, and via various Internet networks such as providers, companies, public institutions, schools, If you reach a provider, company, public institution, school, etc. that has the information you want,
Search for the desired database or internal memory information,
He keeps information on his computer after going through the reverse course.
Here, a host server serving as a contact point of a company, a public institution, or a school, and a host server of a provider are referred to as WWW servers, and the WWW server is used to publish various information distributed on a network as information that can be accessed by anyone. This is defined below as a mechanism.

[0003] Here, there is no well-described method for notifying each user of an update of a file registered in a WWW server on the Internet.

In connection with file update notification, LAN
When updating the file of the above file server, if the user of the updated file is different, a technique of automatically sending a message notifying that the file has been updated only to the previous user, JP-A-3-157
742. That is, since the file stored in the file server device is shared by a plurality of users, when the content of the file is updated, it is necessary to notify the previous user of the updated content by e-mail or the like. Therefore, in the file server device connected to the data transmission network, the update check means for determining whether the content of the stored file has been updated, and the file content has been updated by the update check means. At this time, the user name is read from the attribute of the file and the user name checking means for determining whether the user name is the same from the attribute of the previous version of the file, and the user name checking means determines that the user name is different. Message transmission means for transmitting a message notifying the previous user of the update of the contents when the previous operation has been performed. In this way, a message is automatically sent to the previous user indicating that the file has been updated, so that the user who has received the message can easily determine whether the file after storing is updated. When using the same file, there is no need to check if the contents of the file have been updated. Further, it is described that the user who has updated the file does not need to send a message to the immediately preceding user every time the file is updated, so that there is no time taken for message transmission work.

[0005]

However, in the prior art, since only a message is transmitted to the immediately preceding user, the general user accesses the WWW server again to view the data of the application or the like that has been viewed once, and obtains the target data. Until is confirmed, it cannot be determined whether the data held by the WWW server is the same as that previously viewed or has been updated. Therefore, even if it has not been updated, the user has to access a WWW server that does not need to be browsed again, and there is a problem that wasteful time is wasted.

Further, as described above, since the client, which is the user, generates useless access, the traffic on the Internet is increased, and extra packets are sent on the Internet. There was a problem that it caused congestion.

[Object of the Invention] In order to solve the above-mentioned problems, the present invention detects that the data of the WWW server has been updated in a WWW server used on the Internet, and stores the detection result in advance. By sending e-mail to registered users, reducing unnecessary traffic on the Internet, eliminating unnecessary operations and time on the client side, and preventing congestion on the WWW server side. With the goal.

[0008]

According to the present invention, when data in a WWW server is updated, a registered user is notified by e-mail.

[0009]

The present invention also relates to an update notification system comprising a plurality of WWW servers used on the Internet and having a plurality of clients, wherein the plurality of WWW servers
The first WWW server A among the plurality of clients
First client A of the cement is, the time that is in contact with the second file B second WWW server B's first
