Thus, the execution designation of the process 21 and the remittance source A
The URL 41 including the process specifying information indicating the designation is transmitted from the Web browser 3 to the Web server 2.

Next, since the received process specifying information of the URL 41 includes the transmission source A designation, the fact that the remittance source is the account A is stored in the Web server 2. Also, this Web server 2
The balance of the account A stored in is read out.
Here, it is assumed that the balances of the accounts A to C are “100”, respectively, and the balance “100” of the account A is read out of them. The HTML data 5 relating to the remittance amount designation screen 32 for displaying the balance of the account A and inputting the remittance amount
1 is transmitted from the Web server 2 to the Web browser 3 (process 21).

In the Web browser 3, the received H
In accordance with the contents of the TML data 51, the remittance amount designation screen 32 displaying the balance of the account A is displayed.

Next, the user inputs a remittance amount on the remittance amount designation screen 32. Here, the remittance amount "50"
Is entered.

As a result, the URL 42 including the process specifying information indicating the execution designation of the process 22 and the designation of the remittance "50"
Is transmitted from the Web browser 3 to the Web server 2.

Next, the fact that the remittance amount “50” has been input is stored in the Web server 2 because the received process specifying information of the URL 42 includes the remittance amount “50” designation. Further, the remittance source account A stored in the previous process is read, and the remittance amount “50” is subtracted from the balance “100” of the account A and stored. Then, the HTML data 52 relating to the remittee designation screen 33 for designating the remittee is transmitted from the Web server 2 to the Web browser 3 (process 22).

In the Web browser 3, the received H
A remittee designation screen 33 is displayed according to the contents of the TML data 52.

Next, the user inputs a destination on the remittance destination designation screen 33. Here, it is assumed that remittance destination B is selected.

Thus, the execution designation of the process 23 and the transmission destination B

Next, the user inputs a remittance amount on the remittance amount designation screen 32, and it is assumed that an incorrect remittance amount "10" is input at this time.

Thus, the URL 42 including the process specifying information indicating the process 22 execution designation and the remittance amount “10” designation
Is transmitted from the Web browser 3 to the Web server 2.

Next, the fact that the remittance amount “10” has been input is stored in the Web server 2 because the received process specifying information of the URL 42 includes the remittance amount “10” designation. Further, the remittance source account A stored in the previous processing is read out, and the remittance amount “10” is subtracted from the balance A of this account A “100” and stored. Then, the HTML data 52 relating to the remittee designation screen 33 for designating the remittee is transmitted from the Web server 2 to the Web browser 3 (process 22).

In the Web browser 3, the received H
A remittee designation screen 33 is displayed according to the contents of the TML data 52.

Here, when the user notices that the remittance amount has been entered incorrectly, the display screen is returned to the remittance amount designation screen 32 by the return button of the Web browser 3, and the normal remittance amount "5"
It is assumed that "0" has been input.

Then, the processing 22 is designated for execution and the remittance amount is “5”.
The URL 421 including the process specifying information indicating “0” designation is
Sent from the web browser 3 to the web server 2.

Next, the fact that the remittance amount 50 has been input is stored in the Web server 2 because the received process specification information of the URL 421 includes the remittance amount “50” designation. Further, the remittance source account A stored in the previous process is read, and the remittance amount “50” is subtracted from the balance “90” of the account A and stored. Then, the HTML data 52 relating to the remittee designation screen 33 for designating the remittee is transmitted to the Web server 2.
Is transmitted to the Web browser 3 (step 22).

In the Web browser 3, the received H
A remittee designation screen 33 is displayed according to the contents of the TML data 52.

Next, the user inputs a destination on the remittance destination designation screen 33. Here, it is assumed that remittance destination B is selected.

Thus, the process 23 execution designation and the transmission destination B
The URL 43 including the process specifying information indicating the designation is transmitted from the Web browser 3 to the Web server 2.

Next, since the received process specifying information of the URL 43 includes the destination B designation, the balance of the account B of the remittee is read, and the remittance stored in the previous process is read. The remittance amount is added to the account B of the remittance destination and stored. Here, since account B has a balance “100” and a remittance amount “50” is added, account B has a balance “15”.
0 ".

Then, the HTML data 53 relating to the balance screen 34 for displaying the balances of the accounts A to C is transmitted from the Web server 2 to the Web browser 3 (process 23).

In the Web browser 3, the received H
According to the contents of the TML data 53, a balance screen 34 displaying the balances of the accounts A to C is displayed.

In the above processing, the screen 22 on the Web browser 3 is switched by the return button, so that the processing 22 is executed twice. Therefore, remittance "10" and remittance "50" are deducted from account A,
Only the second remittance amount “50” is added to the balance of the account B.

Therefore, in the above-described processing, the order of operations to the Web browser 3 is changed by the back button, so that the execution order of the processing is also changed, and the result is inconsistent.

Such inconsistency occurs not only when the return button is pressed but also when a URL unrelated to the processing is input to the text input section of the Web browser 3 during the processing. There are cases. Furthermore, U which is stored in advance in the storage unit of the Web browser and has no relation to the processing.
This may also occur when the user selects an RL during processing and sends it to the Web server. Furthermore, H which is stored in advance in the storage unit of the Web browser and has no relation to the processing
This may also occur when the user selects and displays TML data during processing.

The reference URL of the HTTP header added to the reference URL is analyzed, and the process specifying information (hereinafter referred to as “reference process specifying information”) included in the reference URL is extracted. In addition,
As described above, the reference URL is information indicating the screen on which the received URL has been issued. Then, it outputs the extracted reference process specifying information to the determination unit 6e.

When inputting the reference process specifying information from the reference URL analyzing unit 6c, the determining unit 6e reads the process specifying information stored in the storage unit 6d and compares it.

Here, the reference processing specifying information indicates what kind of processing of the Web server 2 generated the screen that issued the URL. On the other hand, the process specifying information stored in the storage unit 6d specifies the process executed in the Web server 2 immediately before.

Therefore, the determination unit 6e compares the process specifying information with the reference process specifying information to determine whether the screen of the Web browser 3a that issued the URL was generated by the process executed immediately before in the Web server 2. Determine whether or not. When the Web server 2 receives the URL from the screen generated by the immediately preceding process, the Web server 2 notifies the processing execution unit 6a that the operation order in the Web browser 3a is appropriate. On the other hand, the URL generated from the screen generated by the process executed immediately before
Is not received, the error screen creation unit 6f and the process execution unit 6a are notified that the operation order in the Web browser 3a is inappropriate.

The error screen creation section 6f generates HTML data for the error screen based on the notification from the determination section 6e, and transmits it to the Web server 2.

The processing executed by the Web system 7 including the browser operation management device 6 having the above configuration will be described below.

FIG. 3 is a flowchart showing the operation of the Web system 7 including the browser operation management device 6 according to the present embodiment.

First, as an operation on the Web browser 3a by the user, for example, when a button on the screen displayed on the Web browser 3a is pressed or a hyperlink destination described on the screen is clicked. (S
1) A first URL based on this operation is transmitted (s
2).

The transmitted first URL is received by the Web server 2, and the first URL received by the Web server 2 is transmitted to the processing execution unit 6 a of the browser operation management device 6.

When the first URL is received by the process execution unit 6a, a process execution notification is transmitted from the process execution unit 6a to the Web server 2. In addition, the first input to the process execution unit 6a
Is output to the URL analysis unit 6b, and the first U
The process specifying information included in the RL is stored in the storage unit 6d (s3).

Then, in the Web server 2 to which the processing execution notification is input, the processing based on the processing specifying information included in the first URL is executed (s4), and the HTML data obtained as a result of this processing is transmitted to the Web browser 3a. Sent to.

The HTML data received by the Web browser 3a is displayed on the screen of the Web browser 3a (s5).

When the user again operates the display screen of the Web browser 3a (s6), a second URL based on the operation is transmitted (s7).

Note that the second URL transmitted from the Web browser 3a includes, on the client side, an HTTP header including, as a reference URL, the first URL that caused the generation of the screen that issued the second URL. Has been added.

The transmitted second URL is received by the Web server 2, and the second URL received by the Web server 2 is transmitted to the processing execution unit 6 a of the browser operation management device 6.

When the second URL is received by the processing execution unit 6a, the second URL is transmitted from the processing execution unit 6a to the reference URL.
It is transmitted to the L analysis unit 6c.

Then, in the reference URL analysis unit 6c,
The reference process specifying information included in the HTTP header of the second URL is extracted and output to the determination unit 6e (s
8).

When the reference process specifying information from the reference URL analyzing unit 6c is input to the determining unit 6e, the process specifying information of the first URL stored in the storage unit 6d is used as the determining unit 6e.
Is read by

Here, the process identification information of the first URL stored in the storage unit 6d indicates the process executed immediately before in the Web server 2. Reference U
The reference process specifying information input from the RL analysis unit 6c indicates a process of generating a screen that emits the received second URL.

Therefore, it is determined whether or not the first URL processing identification information stored in the storage unit 6d matches the second URL reference processing identification information input from the reference URL analysis unit 6c. (S
9).

Here, if the determination results match, it is determined that the URL has been transmitted from the screen generated in the immediately preceding process, and that the operation according to the order has been performed. Then, the judging unit 6e notifies the process execution unit 6a that the operation order is appropriate, the process execution unit 6a transmits a process execution notification to the Web server 2, and the Web server 2 executes the process (s10). Data is sent. At the same time, the judgment unit 6e sends the processing execution unit 6
a is notified that the operation order is appropriate, the second URL previously received by the processing execution unit 6a is output from the processing execution unit 6a to the URL analysis unit 6b, and thereby the second URL is stored in the storage unit 6d. 2 is stored. (S)
11).

Thereafter, the HTML data is displayed on the Web browser 3a, and the same processing as that for the second URL is continued until the management of the operation order from the user becomes unnecessary (s12).

On the other hand, if the determination results do not match, it is determined that the URL has not been transmitted from the screen generated in the immediately preceding process and that the operation according to the order has not been performed. Then, the determination unit 6e notifies the error screen creation unit 6f that the operation order is inappropriate, whereby the error screen creation unit 6f creates HTML data for error display (s13). The created HTML data is
The error screen creation unit 6f transmits to the Web server 2
b Transmitted to the browser 3a and displayed on the screen (s1
4). At the same time, if the determination results in the determination unit 6e do not match, the determination unit 6e notifies the processing execution unit 6a of the fact, and the processing execution unit 6a transmits a processing stop notification to the Web server 2. Then, the processing in the Web server 2 is stopped (s15).

Since the specification is stored and matches the processing 21 execution specification and the remittance source A specification extracted by the reference URL analysis unit 6c, a processing execution notification is transmitted from the browser operation management device 6 to the Web server 2. The URL analysis unit 6b extracts the process 22 execution designation and the remittance "10" designation, which are the process identification information of the URL 42, and stores them in the storage unit 6d (process 62).

Next, when the processing execution notification is received, the processing specific information of the URL 42 received in the previous processing 22a includes the specification of the remittance "10", so the remittance "10" is input to the Web server 2. The fact that the operation has been performed is stored. Further, the remittance source account A stored in the previous process is read out, and this account A
The remittance amount “10” is deducted from the balance “100” and stored. Then, the HTML data 52 relating to the remittee designation screen 33 for designating the remittee is transmitted to the Web server 2.
Is transmitted to the Web browser 3a (step 22).

In the Web browser 3a, a remittee designation screen 33 is displayed according to the contents of the received HTML data 52.

Here, it is assumed that the user notices that the remittance amount has been entered incorrectly, returns the display screen to the remittance amount designation screen 32 by the return button of the Web browser 3a, and inputs a normal remittance amount "50".

Then, the process 22 execution designation and the remittance amount “5”
The URL 421 including the process specifying information indicating “0” designation is
Sent from the web browser 3a to the web server 2.

Next, the URL 42 received by the Web server
1 is transmitted to the browser operation management device 6 (process 22).
b).

As a result, the reference URL analysis unit 6c extracts the process 21 execution designation and the remittance source A designation, which are the reference process specifying information of the URL 42, and determines whether the judgment unit 6e matches the process specifying information of the storage unit 6d. Is determined.
Here, the storage unit 6d stores a process 22 execution designation and a remittance amount “10” designation, and the reference URL analysis unit 6c
Since the process 21 execution designation and the remittance source A designation extracted in the above do not match, the process stop notification and the error display HTML data 54 are output from the browser operation management device 6 to the Web server 2 (process 63).

The processing stop notification and error display H
When the HTML data 54 is received, the processing in the Web server 2 is stopped, and the error display HTML data 54 is displayed.
The data is transmitted from the Web server 2 to the Web browser 3a (process 24).
