Abstract

PROBLEM TO BE SOLVED: To exchange data required to be frequently updated without changing any hyper text mark-up language(HTML) syntax in plural home pages by installing a common gateway interface (CGI) program and plural HTML document files inside a WWW server. SOLUTION: When an HTML document file 2 having a 1st home page address is accessed, a WWW browser interpretes the HTML syntax in that file, an HTML document file 4 having a 3rd home page address is called by a WWW server 30 and its data are received and displayed at one part of display area of the WWW browser. Next, the WWW browser lets WWW servers 30 and 31 execute CGI programs 1 and 41 and calls an HTML document file 3 having a 2nd home page address. Then, its data are displayed at another part of the display area.

ce) using a program, a homepage file in a WWW server, and a WWW browser of a computer to display homepage information on the Internet on a computer or an Internet information terminal;
The present invention relates to an Internet homepage display system.

[0002]

2. Description of the Related Art The Internet started with the ARPANET created by the United States Department of Defense's Planning Agency (ARPA) in 1969 by connecting computers from four U.S. universities, and was later supported by a U.S. government foundation The Internet has been expanding by connecting networks one after another and other networks one after another.
The Internet is the collective term for the huge networks connected in this way. That is, all computers
This is a general term for networks. That is, the Internet refers to one large network in which a plurality of computer networks are connected by a protocol called TCP / IP. The Internet is WWW (Wor
ld Wide Web) makes it even easier to use.

[0003] WWW is a mechanism for easily accessing information from all over the world, and is an Internet system for allowing a user to select desired information while clicking on a computer screen with a mouse. WWW
Then, the location of the information is indicated by words with pictures and marks (words with underscores), so you can reach the information you want just by clicking with the mouse. Multimedia-type information that combines graphics and hypertext (marked words) that can be seen in this way is called a homepage. The homepage makes it easy to search and view data on the Internet, such as texts, voices, images, and videos, from around the world.

As a tool for realizing the WWW mechanism,
Software called WWW browser such as Netscape Navigator has been developed, which allows users to browse the screen called the homepage on the Internet, where they could not reach information without inputting difficult commands or searching for a list of file names. Provided a mechanism to do. A homepage is a collection of various data in a computer connected to the Internet, and has an address on the Internet. When a WWW browser receives an instruction on which homepage to go to, it looks up the address, retrieves separate data such as text, images, and audio from the server where the specified homepage is stored, and displays it on a computer. I do.

[0005] In order for a WWW browser to display homepage data on a computer screen, HTML is used.
(Hyper Text Markup Langua
ges). The homepage has data written in this HTML language.
The homepage is based on this HTML language, when you click which words are laid out, which characters are sized, what is the background color, and when the word with the mouse is clicked, Information such as which homepage to display next is written, WW
The W browser interprets the HTML language of the homepage, combines the disparate sentences, images, sounds, etc. as the homepage and displays it on the computer screen. Now you can see beautiful websites like magazines.

The HTML language includes CGI (Com)
There is also a syntax for executing a program on a WWW server called a "mon Gateway Interface" program.

A WWW server having a homepage always incorporates various files including information in the HTML language and a program (HTTPD) for transmitting a file in response to a request from a WWW browser. On the other hand, WWW browsers are incorporated in computers and Internet information terminals that view homepages. As described above, these mechanisms are called WWW, and a server that sends home pages is called a WWW server.

FIG. 10 shows the structure of a conventional home page for dividing and displaying the screen of a WWW browser when different home pages are viewed by a plurality of computers or Internet information terminals. 11 is index. 3 shows the structure of an html file. A WWW server A, a WWW server B, a computer A, a computer B, and a computer C are connected to the Internet. The home page A on the WWW server A is index. htm
1 and an HTML document file named File A, each of which is http: // www. aa. com / homeA
/ Index. html and http: // www. a
a. com / homeA / fileA. html. Also, home page B on WWW server A is index. HTML document file named html and HT named file B
You have ML document files, each with http:
// www. aa. com / homeB / index.
html and http: // www. aa. com / h
homeB / fileB. html. The home page C on the WWW server A is i
ndex. It has an HTML document file named “html” and an HTML document file named “file C”. aa. c
om / homeC / index. html and http
p: // www. aa. com / homeC / file
C. It has an address named html. WW
W server B has HTML document files named file X and file Y, each of which is http: //
/ Www. bb. com / fileX. html and ht
tp: // www. bb. com / fileY. htm
It has an address on the Internet called l. Computer A, Computer B, Computer C
, Each incorporates a WWW browser.

[0009] The index. In the html file, as shown in FIG. 11, an HTM that displays the information of the file X in the first display area of the WWW browser
An L syntax 12 and an HTML syntax 13 for displaying information of the file A in the second display area of the WWW browser are written. Similarly, index. ht
The ml file includes an HTML syntax for displaying information of file X in the first display area of the WWW browser,
The HTML syntax for displaying the information of the file B in the second display area of the WW browser is written. Similarly, index. The html file has an HTML syntax for displaying information of file X in the first display area of the WWW browser, and an H syntax for displaying information of file C in the second display area of the WWW browser.
The TML syntax is written. Here, computer A
When the WWW browser of homepage A accesses homepage A, server A accesses index. ht
The ml file is sent back to the WWW browser, and the WWW browser interprets the HTML document shown in FIG. 11, and the information of file A is displayed in the second display area of the WWW browser, and the information of file X is displayed in the first display area. Is done.
Similarly, when the WWW browser of the computer B accesses the home page B, the information of the file B is displayed in the second display area of the WWW browser, and the information of the file X is displayed in the first display area. Similarly, when the WWW browser of the computer 3 accesses the home page C, the information of the file C is displayed in the second display area of the WWW browser, and the information of the file X is displayed in the first display area. Therefore, each computer A,
In the first display areas of the computer B and the computer C, the information of the file X is commonly displayed. If news information or the like is stored in the file X, WWW
Even if the homepage in the server A is accessed, the news information can be always displayed on the first screen without specifying the address of the file X from the browser.

The FRAME tag (a kind of HTML syntax) for dividing and displaying the display screen of the WWW browser is described in a document such as "Introduction to HTML" (by Laura Limei).

[0011]

According to these conventional methods, when the content of file X, such as news information, is changed, a new news information file (file Y) is used.
Is prepared in the same server, and index. html file 12 in the first display area of the WWW browser.
It is necessary to change the HTML syntax to display the information of the homepage B, and also to the homepage B and the homepage C. This was a very difficult task as the number of homepages increased.

Further, even if file X is changed to another name and file Y is newly changed to file X,
You can change the news information, but this too
The change was difficult. The conventional method has the above problems.

According to the present invention, it is necessary to frequently update news information and the like displayed when a home page is accessed in a part of a display area of a WWW browser of a computer connected to the Internet to view a home page. It is an object of the present invention to provide a method for exchanging data having a number without changing the HTML syntax in a plurality of homepages.

[0014]

In order to achieve the above-mentioned object, an Internet homepage display system according to the present invention provides a CGI program, an HTML document file having a first homepage address, and a second homepage address. And a WWW server having an HTML document file having a third homepage address and an HTML document file having a third homepage address, and a plurality of computers for viewing homepage data are connected on the Internet to view the homepage data. A plurality of computers have WWW browsers installed, and when the CGI program is executed, an HTML having a second homepage address
An HTML document file, which is configured to be invoked with a first home page address, is used to invoke the CGI program and display the resulting data in a portion of a home page display area of a WWW browser. Contains HTML syntax, and
It includes an HTML syntax for retrieving an HTML document file having a third homepage address and displaying it on another part of the homepage display area of the WWW browser.

Further, when the CGI program is executed by a server in which the program is located, an HTML document file in a WWW server corresponding to each time zone according to a time zone in which the program is executed. Is called, the data is passed to the WWW browser, and the HTM is displayed in a part of the display area of the WWW browser.
