t (registered trademark)) board or the like.

The keyboard 16 to the communication board 2
1 is connected to the interface 15, and the interface 15 is connected to the CPU 11 via the bus 14.

Since the personal computer 2 and the personal computer 4 have substantially the same configuration as the WWW server 1, the description of the hardware configuration is omitted.

However, the communication board 21 is, for example, configured by an Ethernet (Ethernet) board in a company, but is configured by a modem for connecting to an Internet service provider in a general home.

Next, a process when the user of the personal computer 4 updates an HTML file constituting a predetermined Web page stored in the WWW server 1 via the Internet 3 will be described.

First, the creator of the Web page starts up the personal computer 4 at home, then starts up the Web page creation software or a general-purpose text editor, and describes the contents of the Web page to be newly provided. Create HTML format file.

Next, the creator of the Web page operates the personal computer 4 to copy the created HTML file to the WWW.
Upload to the server 1 and update the web page.

Here, there are the following two specific methods for uploading a Web page, and in the present invention, the latter is a file upload function of a WWW browser and a WWW browser.
A method of updating a Web page by cooperative processing with a predetermined CGI program of the WW server 1 is used.

First, a general FTP (File Transfer Prot)
ocol) A method using a client program will be described.

In this method, the personal computer 4
To start the FTP client program and transfer the created HTML file to the WWW server 1 as shown in FIG.

In this case, after the creator of the Web page specifies the HTML file to be uploaded (for example, index.html) on the display screen 30 instructing the transfer of the file of the normal FTP client program shown in FIG. ,
When the directory of the WWW server 1 in which the HTML file is to be stored is specified and the transmission button 31 displayed as “transmission (Put)” is clicked, the personal computer 4
Transfers the specified HTML file to the WWW server 1.

The WWW server 1 converts the transferred HTML file (for example, index.html) into an existing HTML file (for example, in
dex.html).

Next, a description will be given of a method of updating a Web page by the cooperative processing of the file upload function of the WWW browser and a predetermined CGI program operating on the WWW server 1.

In this case, as shown in FIG. 5, the creator of the Web page operates the WWW browser running on the personal computer 4 to specify the display screen 40 for instructing the transfer of the file shown in FIG. When an HTML file name (for example, index.html) to be uploaded is input in the field 41 and a transfer button 42 indicating “Transfer HTML file” is clicked, the personal computer 4 downloads the specified HTML file to the WWW. Transfer to server 1. In this case, the WWW server 1 transmits the transferred HTML according to the procedure of a predetermined CGI program file update process.
The file (for example, index.html) is overwritten on an existing HTML file (for example, index.html) stored on a predetermined directory.

In the present invention, the latter method of updating a Web page by the cooperative processing of the file upload function of the WWW browser and the file update function of the WWW server 1 by a predetermined CGI program is used.

Next, FIG. 7 shows an example of a display screen of the WWW browser of the personal computer 4 on the client side of the information providing system according to the present invention, in which the WWW browser is activated. The creator of the Web page specifies the designated field 51 on the display screen 50 for instructing the transfer of the file shown in FIG.
In the HTML file name to be uploaded (for example, inde
x.html), and the radio button 53a for specifying the present as the update date or the radio button 53 for specifying the future
b, input the expected date in the specification fields 54a to 54c for inputting the update date when the future is specified, and finally, "Transfer HTML file" is displayed. Click the transfer button 52. The personal computer 4 converts the specified HTML file into a WWW file.
Transfer to server 1.

As described above, in the window displayed on the screen of the personal computer 4, in addition to the fields of the WWW browser shown in FIG. 6, the update date of the Web page is selected to be either current or future. When the radio buttons 53a and 53b to be selected are arranged and the update date of the HTML file is in the future, a designation field 5 for inputting the scheduled update date of the HTML file
4a to 54c are arranged.

Here, when the update date of the HTML file is the time at which transfer is to be started at this time, the user clicks the radio button 53 a for selecting the update date now and uploads it to the designated field 51. An HTML file name (for example, index.html) is input, and finally, a transfer button 52 displayed as “Transfer HTML file” is clicked to transfer the specified HTML file to the WWW server 1.

In this case, the WWW server 1 places the transferred HTML file (for example, index.html) on a predetermined public directory according to the procedure of a file update process of a predetermined CGI program. Overwrite existing saved HTML file (for example, index.html).

At the same time, the WWW server 1
According to the procedure of the file update process of the program, a numeric string indicating the current date and time is added to the end of the file name of the transferred HTML file (for example, index.html), and a numeric string indicating the date and time is added. The file name is saved as a backup on a predetermined backup directory.

Here, the public directory is freely accessible via the Internet 3 and is set to be readable, while the backup directory is WW
Only the administrator of the W server 1 can access, and access is restricted so that a third party cannot directly read the information via the Internet 3. These public directories and backup directories are stored on the WWW server 1
Are set in different directories of one or a plurality of HDDs 19 provided in the HDD.

On the other hand, if the scheduled date and time at which the HTML file should be updated is a future time after the start of the transfer, the user clicks the radio button 53b for selecting the update date and time in the future.
Designation fields 54a through 54-5 for inputting update date and time
4c, enter the scheduled date and time, and finally, click the transfer button 52 displayed as "Transfer HTML file" to transfer the specified HTML file to the WWW server 1. As a result, the personal computer 4 should update the date and time data specifying the date and time of updating the file.
The HTML file is transferred to the WWW server 1.

In this case, the WWW server 1 uses an existing HTML file (for example, index.html) stored on a predetermined public directory according to the procedure of a file update process of a predetermined CGI program. HTML file (for example, index.htm
A numerical string indicating the scheduled update date and time is added to the end of the file name in l), and the file name with the numerical string indicating the date and time added is saved as a backup on a predetermined backup directory.

FIG. 8 shows a source of an HTML file for displaying an update instruction screen displayed on the WWW browser of the personal computer 4 shown in FIG.

Next, a procedure when the WWW server 1 performs a backup process of an HTML file (index.html) to be updated by a predetermined CGI program will be described with reference to a flowchart of FIG.

Here, the URL of the WWW server 1 is (http: // w
ww.test.com/), and the URL of the update Web page shown in Fig. 7
As (http://www.test.com/update.html) and the URL of the CGI program for update as (http://www.test.com/cgi-
bin / update.cgi), and the public directory (document root directory) of the WWW server 1 is (/ www / d
ata /) and the name of the HTML file to be updated is
(Index.html) and the backup directory is
(/ Www / data / backup /).

In step S11, the WWW server 1
Converts the data received from the personal computer 4
Divide into variables or files. In step S12, the WWW server 1 determines whether the received file is an HTML file, and determines whether the received file is an HT file.
If it is determined that the file is an ML file, step S
Proceeding to S13, it is determined whether or not the update date and time of the file is in the future based on the variables separated in step S11.

If it is determined in step S13 that the update date and time of the file is not in the future, that is, it is determined that the update date and time of the file is current, the process proceeds to step S14.
The WWW server 1 transmits the transferred HTML file (index.h
tml) overwrites and saves the existing HTML file (index.html) stored on a predetermined document root directory (/ WWW / data /) for publication.

In step S15, the WWW server 1
Is a built-in RTC (RealTime Clock), not shown,
Obtain the current date and time generated by a time count program or the like.

In step S16, the WWW server 1
Is a file name obtained by adding a numeric string indicating the current update date and time acquired in step S15 to the end of the file name of the received HTML file (index.html) and adding the numeric string indicating the date and time. Save as a backup on a predetermined backup directory (/ WWW / data / backup /).

Here, for example, if the current date and time are 1
At 16:12 on April 1, 999, (index.
A file with the exact same content as the HTML file (index.html) is automatically saved as a backup with a new file name named html.1999.4.1.16.12).

In step S17, WWW server 1
Sends a predetermined message to the personal computer 4 to display a normal end, and the process ends.

If it is determined in step S13 that the update date and time of the file is in the future, the process proceeds to step S18, where the WWW server 1 determines the scheduled update date and time of the HTML file transferred from the client computer 4 (separated in step 11). Included in the specified variable).

In step S19, WWW server 1
Determines whether the scheduled update date and time obtained in step S18 is in the future, and if it is determined in step S18 that the scheduled update date and time is in the future, the process proceeds to step S20, where the WWW server 1 receives the HTML file (index.htm
l) At the end of the file name, a numeric string indicating the scheduled update date and time acquired in step S18 is added, and the file name with the numeric string indicating the date and time is added to the predetermined backup directory (/ WWW / data / backup /) as a backup.

Here, for example, if the current date and time are 1
If it was 18:24 on April 2, 999, (index.
A file with the exact same content as the HTML file (index.html) is automatically saved as a backup with a new file name named html.1999.4.2.18.24).

At step S21, the WWW server 1
Sends a predetermined message to the personal computer 4 to display a normal end, and the process ends.

In step S19, step S18
If it is determined that the update date and time obtained in step 2 are not in the future, the received date is incorrect, and the process proceeds to step S23, where the WWW server 1 transmits an error message to the personal computer 4 to display the error. , The process ends.

If it is determined in step S12 that the received file is not an HTML file or a file of a predetermined format such as an image file linked to the HTML file, the received file cannot be handled, and the process proceeds to step S22. The WWW server 1 sends an error message to the client computer 4,
An error message is displayed, and the process ends.

As a result of the above processing, the backup directory (/ WWW / data / backup /) of the WWW server 1 stores the original date and time as a file name with an update date and time or a scheduled update date and time added as a file name. HTML file (in
dex.html) is automatically saved as a backup file.

For example, in the backup directory (/ WWW / data / backup /) of the WWW server 1, "index.html.1998.4.23.18.54", "index.html.1998.5.5.23.15", "index. html.1998.7.1.0.0 "and" index.html.1999.12.24.23.59 ".

Here, steps S16 and S20 described above are performed.
In the backup storage process, only the difference data from the HTML file to be updated is stored in the backup directory (/ WWW / dat
a / backup /), the capacity of the HDD 19 required for backup can be reduced.

Next, the WWW when the scheduled update date and time has arrived
The automatic update process by the server 1 will be described with reference to the flowchart in FIG.

In step S30 in FIG. 10, the WWW server 1 determines that a predetermined time (for example, 0:00) has been reached every day based on an automatic update processing program called cron. Then, the process proceeds to the next step S31, and the backup directory (/ WWW / dat
From the HTML file stored in a / backup /), search for the HTML file scheduled to be updated on the current day based on a numeric string added to the end of the file name and indicating the scheduled update date and time.

Then, in the next step S32, when it is determined that the corresponding HTML file to be updated on the current day is searched, in the next step S33, the WWW server 1 converts the searched HTML file into a predetermined HTML file. Document root directory for given publication (/ WWW / dat
a /) existing HTML file (index.ht
ml) and save it.

Thus, at a predetermined time every day, the WWW server 1 automatically generates a Web page based on the HTML file stored in the backup directory (/ WWW / data / backup /). Can be updated.

Next, a case will be described in which the client-side personal computer 2 requests the WWW server 1 for a web page published in the past and browses it.

Here, the URL of the WWW server 1 is changed to (http: // w
ww.test.com/) and U of the search web page shown in FIG.
Let RL be (http://www.test.com/pageview.html)
Enter the URL of the search CGI program (http://www.test.com/
cgi-bin / pegeview.cgi), and the public directory (document root directory) of the WWW server 1 is
(/ Www / data /), the file name of the HTML file to be viewed is index.html, and the backup directory is (/ www / data / backup /).

First, the user operates the WWW browser of the personal computer 2 on the client side to obtain the URL as
(Http://www.test.com/pageview.html) to display the search Web page shown in FIG.

[0086] On this display screen 60, the information published in the past is displayed.
When browsing a Web page, designated fields 61a to 61e for inputting the date and time to browse are arranged. The user on the client side inputs the desired date and time in the designated fields 61a to 61e for inputting the predetermined date and time, and clicks the browse button 62 displayed as "Browse" to specify the designated date and time data. WW
Transfer to W server 1.

FIG. 12 shows a source of an HTML file for displaying an update instruction screen displayed on the WWW browser of the personal computer 4 shown in FIG.

When the date and time data is transferred from the personal computer 2 of the client, the WWW server 1 searches for an HTML file with a file name corresponding to the closest date and time data based on the date and time data. Is transferred to the personal computer 2 on the client side. Thus, the user on the client side can browse the web pages published in the past simply by inputting the desired date and time in the designated fields 61a to 61e for inputting the predetermined date and time.

Next, the processing when the WWW server 1 provides the Web page corresponding to the date and time transferred from the personal computer 4 in accordance with the procedure of the search processing by the predetermined CGI program is shown in the flowchart of FIG. This will be described with reference to FIG.

At step S51, the WWW server 1 C
The PU 11 causes the communication board 21 to receive a predetermined date and time transmitted from the personal computer 2 via the Internet 3. In step S52, the CPU 11 of the WWW server 1 determines whether the date and time received from the personal computer 2 is normal, and if it is determined that the date and time received from the personal computer 2 is normal, the process proceeds to step S53. Based on the received date and time, search the directory (/ WWW / data / backup /) for an appropriate file.

More specifically, the procedure in step S53 is as follows: if there is a file with the same date and time as the designated date and time,
If a file with the same date and time is selected and there is no file with the same date and time as the specified date and time, a file with a date and time that is earlier than that date and closest to the specified date and time is selected. When the date and time before the start of the provision of the information is specified, the WWW server 1 performs a setting indicating that the corresponding file has not been saved.

For example, the CPU 11 of the WWW server 1 removes “index.html” from the file name to be selected, and uses the remaining character string in a computer language called perl.
Converted by a function such as timelocal, 0:00 on January 1, 1970
Find the number of seconds from 0 minutes. The CPU 11 of the WWW server 1 performs the same processing on the received character string of the specified date and time, and selects the file with the date and time closest to the specified date and time based on the obtained number of seconds. .

In step S54, C of WWW server 1
The PU 11 determines whether or not the corresponding file is stored as a result of the search processing in step S53. If it is determined that the corresponding file is stored, the process proceeds to step S55, and the communication board 21 The corresponding file is transmitted to the WWW browser of the personal computer 2 to display the information corresponding to the designated date and time on the personal computer 2, and the process ends.

If it is determined in step S54 that the corresponding file has not been saved, the process proceeds to step S5.
7, the CPU 11 of the WWW server 1
Then, a predetermined error message is transmitted to the personal computer 2 and an error is displayed on the personal computer 2 on the client side, and the process ends.

If it is determined in step S52 that the date and time received from the personal computer 2 is not normal (for example, the month is set to 13 months), the process proceeds to step 56, where the CPU 11 of the WWW server 1 communicates. The board 21 is caused to transmit a predetermined error message to the personal computer 2 so that the client computer 2
To display an error, and the process ends.

In this manner, the WWW server 1 can provide the personal computer 2 with information corresponding to the designated date and time.
