The first storage device 34 stores Web page data. Web pages are typically formatted by a computer programming language known as Hypertext Markup Language ("HTML"). Therefore, a normal Web page includes text in which format commands called tags are embedded. The web browser parses the HTML script to display the text in a specified format.

Web pages contain, in addition to HTML text, computer program code commonly known as applets. When the WWW browser 30 displays a Web page in which a code for designating an applet is embedded (described), the applet is downloaded from the server 12 where the Web page resides to the client 10 where the WWW browser 30 resides. You. The applet is then executed by the WWW browser 30 therein. Applets are generally available in the United States,
Written in an object-oriented programming language such as the Java programming language developed by Sun MicroSystems of California (Java is a registered trademark of Sun MicroSystems, USA).

FIG. 5 is a diagram showing the information collecting mechanism 36a and the information storing mechanism 36b. The information collecting mechanism 36a is Ja
The va class includes three classes A0, A1, and A2.

The class A0 is an extended class of the applet class, and a static variable T for storing a start time is added. The class A1 is an extension class of the A0 class and defines a run () method. The run () method is a method that is read out when a service is used on a Web page on which an applet is placed. For example, the run () method is read at the start of a search, that is, at the time of sending a request, based on the onClick attribute or the like in the <INPUT> tag. Therefore,
This run () method is the time when the request was sent (start time)
Is collected and stored in a static variable T.

The class A2 is an extension class of the A0 class, and overrides the init () method of the applet class (the init () method having the same name is defined in the class A2). The init () method is a method that is executed only when an applet is read by the WWW browser 30. Therefore, this init () method obtains the time (end time) at which the applet was read, obtains the difference (time required for response) between this end time and the disclosure time stored in the static variable T, and calculates this difference. A process for transmitting to the information storage mechanism 36b is executed.

As described above, the class A1 JAVA applet is placed on the Web page before using the service, and the class A2 JAVA applet is placed on the Web page after using the service, so that the information is displayed on the WWW browser upon use of the service. It can be collected and transmitted to the WWW server.

The information storage mechanism 36b is a CGI (Common Ga
teway Interface) program. The information collection mechanism 36a is an information storage mechanism 36 identified by a URL.
The collected information (the time required for the response) is transmitted to b. The information storage mechanism 36b stores the received information in a log file.

Next, the operation of the information collecting mechanism 36a and the information storing mechanism 36b in the system configured as described above will be described with reference to FIG. Now, the Web page P1 before using the service is displayed on the output device 24 of the client 10. In this state, the information viewer is
A search keyword is input on the W browser 30 and a search start is instructed. The WWW browser 30 sends these pieces of information to the server 12 (request transmission).

When the display control departs from the Web page P1, the class A1 of the information collecting mechanism 36a determines in step S
11, the collected start time TST is stored in the area of the static variable T secured in the memory 22 in the class A0.

The server 12 performs a predetermined service process (database search) in step S21 in response to the request from the client 10, and transmits the resulting data to the client 10 together with the data of the Web page P2 for displaying the result. I will send it back. The WWW browser 30 of the client 10 receives this response, and sends
Display page b2. This display triggers the execution of the class A2 of the information collecting mechanism 36a.

First, the information collecting mechanism 36a starts with step S1.
The time collection process in step 2 is performed to obtain the end time. Then, a start time TST stored in the common area is input. Next, a difference calculation process in step S13 is performed to obtain a time required for a response (response information). Then, the response information is transmitted to the server 12 by the information transmission process in step S14.

The information storage mechanism 36b of the server 12 performs the information storage processing in step S22, receives the response information, and stores it in the log file. When another information viewer tries to receive the service of the server 12 with his / her own WWW browser, the information is first transmitted from the WWW server 32 to the output device of the client 10 owned by the information viewer, as described above. Web page P1 is displayed,
Next, a Web page P2 returned in response to the service request transmission is displayed. Therefore, the response information of such another information viewer is stored in the log file.

In this manner, the Web provided by the server 10
Response information for all information viewers who use the b-page service is collected in the log file. As described above, the present embodiment has the following advantages.

(1) The time required for a Web page service response (response information) is collected by the information collection mechanism 36a executed by the WWW browser 30 of the client 10 and transmitted to the server 12, and the WWW of the server 10 is transmitted. The server 32 collects the received response information in a log file. As a result, the trouble of measuring the time required for the response with a stopwatch or the like can be omitted, and information can be easily collected for analyzing the operation information of the server 10.

(2) Web page P1 before using service
The time from the time when the display control departs from (start time) to the time when the display control passes to the Web page P2 after using the service (end time) is collected as the time required for the response, so that the information viewer feels it. The display waiting time can be accurately collected.

(3) Web pages P1 and P1 for information collection
By mounting the information collecting mechanism 36a on P2, the Web
The time required for the Web page service to respond to all the information viewers who receive the service provided by the pages P1 and P2 can be easily collected in the server 10.

The above embodiment may be modified as follows. In the above embodiment, the client 10 collects the start time and the end time and calculates the response time. However, the client 10 collects only the end time and transmits it to the server 12 as response information. The server 12 may collect the start time at the time of receiving the request from the client 10, calculate the response time based on the start time and the end time received as the response information, and store the response time in the log file.

The information collection mechanism of the above-described embodiment is implemented by using JAVA
It may be realized by a combination of the A script and the cookie. Further, the information storage mechanism may be realized by a network service (reception / processing of an information storage request by socket communication) independent of the WWW server.
