The present invention relates to a method for detecting a double transmission request from browsing software due to an erroneous operation of an operator on a homepage server when information is input and transmitted.

[0002]

2. Description of the Related Art The Internet has become widespread, and its use has been diversified. For example, it is possible to use the Internet to register information and order goods purchases from a homepage. In this case, the operator (Internet user) can use the viewing software to send the input information to the homepage server when the homepage has input items. When the load on the homepage server is light or the load on the communication line is light, a result is immediately returned when the transmission button is selected from the homepage. However, when the load on the homepage server is heavy, when the load on the communication line is high, or when the amount of data as a result of the transmission is large, the time from when the transmission is performed to when the result is returned may be long. At this time, the operator
There is a case where it is thought that the transmission has been performed, but it is actually determined that the transmission has been forgotten, or a case where it is impatient that the transmission is performed again.

There is no problem if the information is simply page information or page information as a result of a search. However, if the above-mentioned operation is performed for information registration using the homepage or order for goods purchase, etc., processing is performed twice, and double registration or 2
An error to place a heavy order will occur. In addition, although the first processing has been completed normally, the retransmission has been performed, and the first processing has been completed normally. It can be. To the operator, it looks as if it has failed, and a situation occurs in which the processing has failed even though the processing has succeeded. As a result, the operator performs the same operation again, and there is a risk that a double registration or a double order will occur.

A conventional example of a system for preventing such double transmission is described in, for example, Japanese Patent Laid-Open No. 11-143944, entitled "Credit Processing System, Credit Processing Method, and Computer-readable Storage Medium for Credit Processing Program". It has been disclosed. This prior art is based on 2
In order to prevent a heavy order, the orderer confirms on the final order confirmation screen whether or not to purchase an item ordered using the viewing software, and selects whether or not to purchase. In some cases, the orderer unconsciously performs the double transmission during the operation. By checking the list of purchased items in the purchase confirmation, the orderer is prevented from ordering unintended products. But,
When the purchaser selects the purchase on the purchase confirmation screen and operates the purchase button, which is the final confirmation, the situation described above may occur and the double operation may be performed. Or it could not be prevented reliably.

[0005]

In the information transmission using the Internet, a double transmission occurs, a double transmission occurs to a homepage server, and a double registration occurs. The reason is that, when the network load or the load on the homepage server is high after the operator presses the transmission button of the viewing software, a response to the transmission request may not be immediately returned. Therefore, when the operator presses the second transmission button, each transmission request is processed by the homepage server, and each processing is normally processed.
This is because double processing occurs. Even if the processing load is not high, even if the operator double-clicks due to an erroneous operation, the processing is performed twice against the intention of the operator.

In some cases, it appears that the process has failed even though the process has been completed normally. The reason is that the processing of the transmission request that first arrives at the homepage server ends normally, and the processing of the subsequent transmission request is determined by the homepage server to be a retransmission request of the processed request, and the operator In the browsing software, a screen for which processing of a subsequent transmission request has failed is displayed after a screen for which processing has been normally completed is momentarily displayed (the screen may not be displayed). Even in such a case, the operator recognizes that the operation has failed.

[0007]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to detect double transmission from a browsing software on a homepage server side when registering and registering information on a homepage provided on the Internet using browsing software. To provide a double transmission detection method for preventing the above-described double transmission or double registration.

[0008]

According to the double transmission detection method of the present invention, when a homepage request is made from browsing software using the Internet, the homepage server stores the hidden information and stores the hidden information in the homepage data. The same value as above is attached as hidden information, and the operator selects the send button on the homepage from the browsing software and compares the value of the transmitted hidden information with the value of the stored hidden information.
Detect duplicate transmissions.

According to a preferred embodiment of the double transmission detection method of the present invention, hidden information is information such as the name of the user input by the homepage requester. The send button is displayed on the screen of the homepage requester. The request result indicating the presence or absence of the double transmission is displayed on the request result screen. Also,
The hidden information can be displayed or hidden on the screen of the viewing software.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration and operation of a preferred embodiment of a double transmission detection method according to the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram showing a configuration of a preferred embodiment of a double transmission detection method according to the present invention. The Internet user (homepage requester) 10 accesses the homepage server 20 by operating an input device such as a keyboard of a personal computer (PC). It is assumed that when the Internet user 10 makes a homepage request to the homepage server 20, there is a homepage request C that needs to detect that double transmission has occurred due to an erroneous operation of the operator. The unique hidden information 2 for detecting this double transmission is described in HTML (Hype
r Text Markup Language) to the text,
Homepage screen transmission processing A for storing the hidden information 1
The hidden information 3 sent by the transmission operation from the operator, which is a homepage request for detecting double transmission, is compared with the hidden information 4 stored in the above-described process A to detect the presence or absence of double transmission. And processing B of the transmission request to be performed.

The processes A and B operate as follows. The hidden information addition processing A is a function for performing dynamic processing on the homepage server 20 provided by the homepage server 20 in the case of requesting a homepage for which double transmission needs to be detected, for example, CGI (Common).
Gateway Interface). By using this function, in order to respond to a request from the plurality of Internet users 10 to the same home page, the hidden information unique to the home page server 20 is generated in the HTML FORM tag, and the home page requester is generated. It is added as hidden information 2 of the hidden attribute of the homepage of the Internet user 10. The hidden information 2 only needs to be unique information, and may be configured by a character string or a number or a combination of both.

The hidden information 2 added as a hidden attribute to the FORM tag is stored in the homepage server 2 by the processing B described above.
The hidden information 1 is stored in the homepage server 20 for use in comparison on the 0 side. In the hidden information comparison process B, the hidden information 4 stored in the process A is compared with the hidden information 3 sent from the browsing software that has made the transmission request, and it is determined whether the transmission is double transmission. In addition, hidden information 4
Is the same as the hidden information 1.

Next, the overall operation of the preferred embodiment of the double transmission detection method according to the present invention shown in FIG. 1 will be described in detail with reference to the flowcharts of FIGS. FIG. 2 is a flowchart showing the processing operation of transmission A of the homepage screen shown in FIG. On the other hand, FIG. 3 is a flowchart showing a processing operation of the transmission request processing B shown in FIG.

First, the flowchart of the transmission A of the homepage screen shown in FIG. 2 will be described. When the Internet user 10 makes a homepage screen transmission request C to the homepage server 20, an exclusive setting is made in order to obtain unique hidden information in the homepage server 20, that is, an exclusive setting for information acquisition is made (step S11). ). If another Internet user 10 has previously requested the same home page (step S11: exclusion NG), the exclusion of hidden information acquisition has already been set, so in step S11 until the exclusion is released. You will have to wait.
On the other hand, when exclusion of hidden information acquisition is not set or exclusion is set and exclusion is released (step S11: exclusion O
In K), exclusion for setting hidden information of the Internet user 10 is set, and the hidden information is obtained (step S12). In the acquisition of the hidden information (step S12), in order to detect the double transmission for the transmission A on the homepage screen, the homepage server 20 acquires the hidden information that is unique. The acquired hidden information is stored as hidden information 1 in the homepage server 20.

Next, the exclusion for acquiring unique hidden information is released (step S13). Further, a homepage screen is created (step S14). This step S
In step 14, the acquired hidden information 1 is embedded in the page data of this home page as the hidden attribute of the HTML FORM tag, and transmitted to the viewing software of the home page requester. The Internet user 10 inputs data necessary for page data displayed on the viewing software and selects data. Then, the data input and the selected data are transmitted to the homepage server 20 by pressing the transmission button E, and the hidden information 3 of the hidden attribute is transmitted to the homepage server 20 to end the processing (step S15).

Next, a flowchart of the processing B of the transmission request will be described with reference to FIG. When the above-mentioned hidden information 3 is transmitted from the Internet user 10 who is the homepage requester to the homepage server 20, exclusion is confirmed in processing B of the transmission request, that is, exclusion is set for the information (step S21). If exclusion has already been set by the hidden information 3 (step S21: exclusion NG), the process waits until the exclusion is released. On the other hand, when the exclusion is not applied or when the exclusion of the previously transmitted request is released (step S21: exclusion OK), the exclusion is set by the hidden information 3. By setting the exclusion in the above-described step S21, 2 due to an erroneous operation by the operator is set.
Even if multiple transmissions occur, the exclusion is set in the processing of the transmission information that arrives first, so that when transmission information that arrives later due to erroneous operation arrives, the exclusion is set by exclusion by hidden information. , The processing for the same transmission can be controlled.

Next, it is checked whether or not the hidden information 4 having the same value as the transmitted hidden information 3 is stored in the homepage server 20 (step S22). As a result of this check, if the same hidden information is stored (step S22: exists),
The process proceeds to step S23, and if not stored (step S22: does not exist), the process proceeds to step S26.
If the hidden information 4 is stored (step S22: exists), the hidden information is discarded (step S2).
3). That is, the hidden information 4 having the same value as the transmitted hidden information 3 stored in the homepage server 20 is deleted. Next, the exclusive setting of the transmitted hidden information 3 is released (step S24). Thus, the process ends without occurrence of double transmission, and it can be identified that double transmission due to an erroneous operation has not occurred (step S25). Thereafter, the homepage server 20 executes the original request processing for the information input or selected on the homepage other than the hidden information 3 sent from the operator.

On the other hand, if the occurrence of double transmission is detected in the above-described information presence / absence check in step S22 (step S22: does not exist), the setting of exclusion of the hidden information 3 is released (step S26). . And (2
Double transmission has occurred), and it is possible to identify that double transmission has occurred (step S27). Thereafter, the homepage server 20 performs a process of occurrence of double transmission due to an erroneous operation by the operator, thereby preventing double registration.

As described above, according to the present invention, the hidden information is transmitted by adding the hidden information to the homepage server 20 and the homepage data in response to the homepage request by the viewing software, and transmitted by the operator. The presence / absence of the hidden information sent from the user and the hidden information stored in the homepage server 20 are checked (detected). Thus, even if the sender erroneously performs the double transmission, the double transmission can be detected, and the processing based on the double transmission detection can be controlled on the homepage server 20 side.

Next, the operation of the double transmission detection method according to the present invention will be described based on a specific example. FIG. 4 shows a flow of processing when the Internet user 10 erroneously operates the send button 2E in a situation in which a response after double-clicking or sending the homepage send button is not quickly returned. As shown in FIG. 4, the Internet user 10 makes a transmission request 2A of a required homepage using browsing software. That is, a request is issued to the homepage server 20 from the browsing software through the request 2C for the homepage screen.

In the homepage screen transmission 2A, dynamic processing is performed using the above-described functions such as CGI, and the homepage server 20 generates hidden information 21 that is unique. The generated value of the hidden information 21 is transmitted to the browsing software of the homepage requester by filling the hidden information 22 as a hidden attribute of an HTML FORM tag. The home page screen 2D sent from the home page server 20 is displayed on the screen of the browsing software of the home page requester (Internet user) 10. However, the hidden information 22 is not displayed on the screen of the viewing software because of the hidden attribute. The hidden information 22 may be displayed on the screen as a series processing number.

The Internet user (homepage requester) 10 sets input items or selection items on the homepage screen 2D and presses a send button 2E to input / select information 2H-1 and hidden information 2 on the homepage screen.
3-1 is sent to the homepage server 20 together. Upon receiving the hidden information 23-1 sent from the homepage requester 10, the homepage server 20 receives the hidden information 23-1 in a transmission request process 2B-1. Then, according to the flowchart of FIG. 2, it is determined whether or not double transmission is caused by an erroneous operation. In this case, in the flowchart of FIG. 3, processing is performed in the order of step S21 → step S22 → step S23 → step S24. As a result, it is determined that the request from the homepage requester 10 is not a request by double transmission, the registration processing of the information 2H-1 actually sent is performed, and the request result screen 2F indicates that processing has been completed normally. And a request result screen 2F is displayed on the browsing software.

Next, when double transmission occurs due to erroneous operation by the homepage requester 10, information 2H-2 input / selected on the homepage screen 2D and hidden information 23-2 are newly sent to the homepage server 20. Come. The homepage server 20 receives the hidden information 23-1 sent from the homepage requester 10 in the transmission request process 2B-2, and determines whether or not double transmission due to an erroneous operation is performed according to the flowchart of FIG. Do. In this case, when the processing of the information transmitted by the information 2H-1 input / selected on the homepage screen is determined to be the double transmission by the transmission request processing 2B-1, FIG. In the exclusion check step S21 for the hidden information in the flowchart, the process waits until the exclusion is released. If the exclusion has already been released, the process proceeds to the next step.

When the exclusion is released in step S21, exclusion is set by the hidden information 23-2. When the setting of the exclusion is completed, in step S22 of checking the presence or absence of the hidden information, it is checked whether or not the hidden information 24 having the same value as the hidden information 23-2 is stored in the homepage server 20. In this case, since the hidden information 24 has already been deleted in the processing of the information 2H-1 input / selected on the homepage screen, there is no hidden information in this step S22, and this is an erroneous operation due to the second or subsequent transmission. It turns out that. Therefore, in the next step, a hidden information exclusion release step S26, the exclusion setting of the hidden information hidden information 23-2 is released, and the occurrence of double transmission is recognized. The fact that the operation of the send button 2E on the homepage screen 2D has been performed twice or more is sent to the request result screen 2G, the request result screen 2G is displayed on the viewing software, and the homepage requester 10 is notified that the double operation has been performed. Can be notified.

FIG. 5 is a specific example of an image displayed on the display screen of the viewing software. In FIG. 5, the name (Taro Yamada) G of the homepage requester 10 is input and displayed above the send button E. FIG. 6 is similar to FIG.
HTML (Hyper Text Markup Languag)
This is a description example according to e).

The configuration and operation of the preferred embodiment of the double transmission detection method according to the present invention have been described above. However, such an embodiment is merely an example of the present invention and does not limit the present invention in any way. It will be readily apparent to those skilled in the art that various modifications can be made in accordance with the particular application without departing from the spirit of the invention.

[0028]

As will be understood from the above description, the double transmission detection method of the present invention has the following practically significant effects. First, in the information registration using the homepage, the homepage requester detects double transmission due to an erroneous operation, so that double registration of information can be reliably prevented. The reason is that the presence or absence of double transmission can be checked using hidden information.

In addition, a short time 2
In the case of multiple transmission, a subsequent result screen is displayed immediately after the first result screen is displayed. As a result, when the display contents are different between the first result screen and the subsequent result screen, only the last result screen is displayed, and only the last result screen can be viewed from the operator. However, since the presence or absence of the double transmission can be checked, the first request result can be returned to the homepage requester. The reason is that by recording the contents of the first request processing, even if a second or subsequent transmission request occurs, only the result of the first processing is returned.
