2. Description of the Related Art First, a proxy server will be described.
The proxy server is located between the web server and the client (terminal), and transmits a request from the client to the web server.
A device or software that communicates to the B server and returns a response from the WEB server to the client. For example, even in an environment where the network is shut off from outside the company for security, it can be accessed outside the company via the proxy server. It is also used to prevent unauthorized intrusion from the outside. Another major function is that the proxy server temporarily holds the data passed to the client in a data acquisition request from a certain terminal, and sends the same data acquisition request from another client via the proxy server. There is a function called "cache function" that speeds up the response of a request by returning the held data to the client when the operation is performed.

With the diversification of Internet usage forms such as Web browsing and e-mail, it is essential to enhance the functions of elements constituting the Internet environment, such as a proxy server, and to provide users with a more comfortable Internet usage environment. Therefore, various technical developments are being performed. The most widespread use of the Internet is to browse HPs (homepages) scattered around the world. H
The contents of P are various, such as a personal page, a company page, and a commercial page, and the range is widened from entertainment purposes to business purposes such as collecting and searching for technical information. In addition, in the present situation in which a network is established, communication using data communication, such as e-mail, has become commonplace in exchanging information between individuals and companies.

[0004] In such an environment, improvement of a more comfortable environment is required from the viewpoint of how quickly and efficiently useful information obtained on the Internet can be utilized. For example, if a user finds highly useful information on the Internet and tries to transmit it to relevant people in the company, the user temporarily suspends the browser operation used for browsing the website and uses an e-mail application. Work such as inputting unnecessary information and sending an e-mail. While the use of the Internet has become frequent and information can be collected promptly, interruption of information transmission operation reduces the efficiency of work itself. From such a viewpoint, there is a demand for a function of efficiently utilizing various information scattered on the Internet among a plurality of user terminals.

Send a data acquisition request based on the format (S
82). The request transmitted from the terminal is once received by the proxy server (S83). That is, the request receiving unit 6 receives the request, and the request analyzing unit 7 analyzes the received request. The proxy server modifies the request from the terminal based on the HTTP format and transmits the request to the actual URL (S84). Request from proxy server is WEB
It is received by the server (not shown) (S85). Predetermined W
The data requested by the terminal is downloaded from the EB server to the proxy server (S86). The proxy server receives data from the WEB server (S87).
The proxy server transmits the data to the terminal (S8
8). Thereby, the HP of the specified URL is displayed on the terminal. Next, when the user wants to transmit useful information on the HP to another user, another application such as a mailer is activated (S89). Enter the e-mail address of the user to be transmitted to the launched application, enter the contents of the information obtained from the Internet,
The e-mail is transmitted (S90). When the transmission is completed, another application is terminated (S91). The terminal starts up the browser again, or makes the browser usable (active), and resumes browsing the Internet (S9).
