  FIG. 5 is a configuration block diagram showing an example of an apparatus using such a conventional login timeout setting method. In FIG. 5, 1 is a Web client such as a computer on which a Web browser operates, 2 is a Web server such as a server on which an application of the Web server operates, and 100 is a general-purpose network such as the Internet or an intranet.

  Web client 1 is connected to network 100, and Web server 2 is also connected to network 100.

  FIG. 6 is a block diagram showing a specific example of the conventional example shown in FIG. In FIG. 6, 1, 2 and 100 are assigned the same reference numerals as in FIG. 5, 3 is a processing means for performing control processing of the entire Web client 1 such as a CPU (Central Processing Unit), and 4 is an input of a mouse, a keyboard or the like. Output means 5 is a display means such as a CRT (Cathode Ray Tube) or LCD (Liquid Crystal Display), and 6 is a processing means for performing control processing of the entire Web server 2 such as a CPU.

  In FIG. 6, the output of the input / output means 4 is connected to the processing means 3, and the output signal from the processing means 3 is connected to the display means 5. The processing unit 3 and the processing unit 6 are connected to each other via the network 100.

  Here, the operation of the conventional example shown in FIG. 5 (FIG. 6) will be described with reference to FIGS. FIG. 7 is a flowchart for explaining the operation of the processing means 3 of the Web client 1, and FIG. 8 is a flowchart for explaining the operation of the processing means 6 of the Web server 2.

  In “S001” in FIG. 7, the processing unit 3 of the Web client 1 determines whether or not the user has performed a login operation to the Web server. Specifically, it is determined whether or not a control component such as a login button displayed on the display unit 5 has been operated by the input / output unit 4 such as a mouse.

  If it is determined that a login operation has been performed in “S001” in FIG. 7, the processing unit 3 transmits a login request to the Web server 2 via the network 100 in “S002” in FIG. Log in to the Web server 2.

  If it is determined that the login operation has not been performed in “S001” in FIG. 7, the processing unit 3 ends the process.

  After logging in to the Web server 2, the processing means 3 determines whether or not the user has performed a logout operation from the Web server 2 in "S003" in FIG. Specifically, it is determined whether or not a control component such as a logout button displayed on the display means 5 has been operated by the input / output means 4 such as a mouse.

  If it is determined that the logout operation has not been performed in “S003” in FIG. 7, the processing means 3 determines whether or not the timeout reset request cycle has been reached in “S004” in FIG. If the reset request cycle has not been reached, the process returns to the “S003” step in FIG.

  If the request period for timeout reset has been reached in “S004” in FIG. 7, the processing means 3 sends a timeout reset request to the Web server 2 via the network 100 in “S005” in FIG. At the same time, the process returns to the step “S003” in FIG.

  If it is determined that a logout operation has been performed in “S003” in FIG. 7, the processing means 3 transmits a logout request to the Web server 2 via the network 100 in “S006” in FIG. Log out from the Web server 2.

  On the other hand, in “S101” in FIG. 8, the processing unit 6 of the Web server 2 determines whether or not a login request is received from the Web client 1 via the network 100.

  If it is determined that the login request is received in “S101” in FIG. 8, the processing means 6 performs the login process for the Web client 1 in “S102” in FIG. 8 and the step “S103” in FIG. Proceed to

  If it is determined that the login request is not received in “S101” in FIG. 8, the processing means 6 ends the processing.

  In "S103" in FIG. 8, the processing means 6 resets the logout timer, specifically, sets a fixed-length login timeout value that is preset in the logout timer that is a down counter. Then, in “S104” in FIG. 8, the processing means 6 starts a countdown of the logout timer.

  In “S105” in FIG. 8, the processing means 6 determines whether or not a timeout reset request has been received from the Web client 1 via the network 100.

  If it is determined that a timeout reset request is received in “S105” in FIG. 8, the process returns to the step “S103” in FIG. 8 to reset the logout timer, specifically, to the logout timer that is a down counter. Reset the preset login timeout value.

  If it is determined that the timeout reset request has not been received in “S105” in FIG. 8, the processing means 6 refers to the value of the logout timer in “S106” in FIG. Large, in other words, it is determined whether or not the login timeout period has elapsed.

  If it is determined that the login timeout period has not elapsed in “S106” in FIG. 8, the process returns to the step “S105” in FIG. 8, and if the login timeout period has elapsed in “S106” in FIG. If “S107” in FIG. 8 is determined, the processing unit 6 forcibly logs out the Web client 1 as a login timeout process.

  As a result, when the Web server 2 sets the login timeout time in the down counter and counts down, the Web client 1 periodically resets the login timeout time of the down counter, and the down counter becomes “0”. Since the Web server 2 forcibly logs out the Web client 1, it is possible to prevent useless occupation of the connection to the Web server.

  However, in the conventional example shown in FIG. 5 (FIG. 6), the login timeout time is a fixed length value that is set in advance. Therefore, due to the specifications of the Web client 1 and the internal load status, There was a problem that the logout timer could not be reset in time and the logout might be forcibly logged out if the interval became long.

Moreover, in order to avoid such an unexpected forced logout, it is possible to cope with a longer login timeout period, but the login timeout period must correspond to a Web client having the lowest possible specification. There is a problem that it is impossible to efficiently prevent wasteful occupation of the connection to the Web server.

  Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a configuration block diagram showing an embodiment of an apparatus using a login timeout setting method according to the present invention.

  In FIG. 1, 7 is a Web client such as a computer on which a Web browser operates, 8 is a Web server such as a server on which an application of the Web server operates, and 101 is a general-purpose network such as the Internet or an intranet.

  The Web client 7 is connected to the network 101, and the Web server 8 is also connected to the network 101.

  FIG. 2 is a block diagram showing a specific example of the embodiment shown in FIG. In FIG. 2, 7, 8 and 101 are given the same reference numerals as in FIG. 1, 9 is a processing means for performing control processing of the entire Web client 7 such as a CPU, 10 is an input / output means such as a mouse and keyboard, and 11 is Display means such as a CRT or LCD, 12 is a processing means for performing control processing of the entire Web server 2 such as a CPU, 13 is a reception time holding means for holding the reception time of a timeout reset request from the Web client 7, and 14 is a Web client 7 is a timeout value calculation means for calculating a login timeout value according to the specifications and load of No. 7. Reference numerals 13 and 14 form processing means 12.

  In FIG. 2, the output of the input / output means 10 is connected to the processing means 9, and the output signal from the processing means 9 is connected to the display means 11. The processing unit 9 and the processing unit 12 are connected to each other via the network 101, and the output of the reception time holding unit 13 is connected to the timeout value calculation unit 14.

  Here, the operation of the embodiment shown in FIG. 1 (FIG. 2) will be described with reference to FIGS. FIG. 3 is a flowchart for explaining the operation of the processing means 9 of the Web client 7, and FIG. 4 is a flowchart for explaining the operation of the processing means 12 of the Web server 8.

  In “S201” in FIG. 3, the processing unit 9 of the Web client 7 determines whether or not the user has performed a login operation to the Web server 8. Specifically, it is determined whether or not a control component such as a login button displayed on the display unit 11 has been operated by the input / output unit 10 such as a mouse.

  If it is determined in step S201 in FIG. 3 that no login operation has been performed, the processing unit 9 ends the process.

  If it is determined that a login operation has been performed in “S201” in FIG. 3, the processing means 9 transmits a login request to the Web server 8 in “S202” in FIG. In “S <b> 203”, the processing unit 9 logs in the Web server 8 by continuously transmitting a timeout reset request to the Web server 8 at a transmission interval designated from the Web server 8 via the network 101.

  After logging in to the Web server 8, the processing means 9 determines whether or not the user has performed a logout operation from the Web server 8 in "S204" in FIG. Specifically, it is determined whether or not a control component such as a logout button displayed on the display unit 11 has been operated by the input / output unit 10 such as a mouse.

  If it is determined that the logout operation has not been performed in “S204” in FIG. 3, the processing means 9 determines in S205 in FIG. If the reset request cycle has not been reached, the process returns to the step "S204" in FIG.

  If the time-out reset request cycle has been reached in “S205” in FIG. 3, the processing means 9 issues a time-out reset request to the Web server 8 via the network 101 in “S206” in FIG. At the same time, the process returns to the step “S204” in FIG.

  If it is determined that a logout operation has been performed in “S204” in FIG. 3, the processing means 9 transmits a logout request to the Web server 8 via the network 101 in “S207” in FIG. Log out from the Web server 8.

  On the other hand, in “S301” in FIG. 4, the processing unit 12 of the Web server 8 determines whether or not a login request is received from the Web client 7 via the network 101.

  If it is determined that a login request has been received in “S301” in FIG. 4, the processing means 12 then issues a timeout reset request that is continuously transmitted a plurality of times at a specified interval in “S302” in FIG. The reception time is received and held in the reception time holding means 13.

  Further, in “S302” in FIG. 4, the processing unit 12 causes the timeout value calculation unit 14 to calculate the login timeout value based on the reception time of the timeout reset request held in the reception time holding unit 13.

For example, when the designated transmission interval is “ _TL ”, the number of continuous receptions is “y”, and the reception time of each timeout reset request is “t _N (N = 1 to y)”, the timeout reset request The average reception interval “T _A ” of the reception time is
T _A = (t _y −t _y−1 ) + (t _y−1 + t _y−2 ) +... + (T ₂ −t ₁ ) / (y−1)
= (T _y -t ₁ ) / (y-1) (1)
However, if T _A <T _L , T _A = T _L.
It becomes.

Here, when the login timeout value set in advance is “X _F ”, the login timeout value “X _V ” set according to the specifications of the Web client 7 is
_{X V = X F + (T} A -T L) × X F / T L (2)
Is required.

  Thereafter, in “S303” in FIG. 4, the processing means 12 performs the login process for the Web client 7 and proceeds to the step “S304” in FIG.

  If it is determined that the login request has not been received in “S301” in FIG. 4, the processing means 12 ends the processing.

In “S304” in FIG. 4, the processing means 12 resets the logout timer, specifically, sets the login timeout value “X _V ” calculated by Expression (2) to the logout timer that is a down counter. Then, in “S305” in FIG. 4, the processing means 12 starts a countdown of the logout timer.

  In “S 306” in FIG. 4, the processing means 12 determines whether or not a timeout reset request has been received from the Web client 7 via the network 101.

If it is determined that a timeout reset request has been received in “S306” in FIG. 4, the process returns to the step “S304” in FIG. 4 to reset the logout timer, specifically, to the logout timer as a down counter. Reset the login timeout value “X _V ”.

If it is determined that the timeout reset request is not received in “S306” in FIG. 4, the processing means 12 refers to the value of the logout timer in “S307” in FIG. In other words, it is determined whether or not the login timeout time “X _V ” has elapsed.

If it is determined that the login timeout time “X _V ” has not elapsed in “S307” in FIG. 4, the process returns to the step “S306” in FIG. 4, and the login timeout in “S307” in FIG. If it is determined that the time “X _V ” has elapsed, the processing unit 12 forcibly logs out the Web client 7 as a login timeout process in “S308” in FIG.

As a result, when the Web client 7 logs in, the Web server 8 receives a time-out reset request that is continuously transmitted a plurality of times at an interval specified by the Web server 8, obtains an average value of the reception intervals based on the reception time, and specifies the specifications of the Web client. The login timeout value “X _V ” corresponding to the load status is calculated and set in the logout timer (down counter), thereby setting the login timeout corresponding to the specifications of the Web client on which the Web browser operates and the load status. Is possible.

In the embodiment shown in FIG. 1 (FIG. 2), the login timeout value “X _V ” corresponding to the specifications and load status of the Web client is calculated only when the Web client 7 logs in. After the login, the processing means 12 of the Web server 8 periodically recalculates the login timeout value, so that even if the load situation deteriorates (the load increases) after the login, it is possible to respond dynamically. Is possible.

Specifically, after the web client 7 logs in, the processing means 12 of the web server 8 includes a timer for recalculating the login timeout value, and from the web client 7 at a fixed period (period in which the timer times up). The timeout reset request is continuously transmitted a plurality of times and the step shown in “S302” in FIG. 4 is executed to recalculate the login timeout value “X _V ”.

In the embodiment shown in FIG. 1 (FIG. 2), the login timeout value “X _V ” corresponding to the specifications and load status of the Web client is calculated only when the Web client 7 logs in. Depending on the load status after login, the reception time of the timeout reset request sent from the client 7 at regular intervals is held each time, and the login timeout value is recalculated based on the held reception time when the timeout reset request is received. It is possible to set a login timeout value that corresponds efficiently.

Specifically, the step shown as “S302” in FIG. 4 based on the latest y reception times when receiving the timeout reset request among the reception times of the timeout reset request transmitted from the Web client 7 at regular intervals after login. Similarly, the login timeout value “X _V ” is recalculated.

  In the embodiment shown in FIG. 1 (FIG. 2), the login timeout value on the Web server 8 side is dynamically changed according to the specifications and load status of the Web client 7. 9 may cope with the load fluctuation by shortening the transmission interval for transmitting the timeout reset request.

Specifically, the processing means 9 of the Web client 7 has the transmission interval designated “T _L ” acquired from the Web server 8 acquired from the Web server 8 and the average reception interval “T _A ” at the Web server 8. Request timeout reset period “T _R ”
T _R = T _L × (T _L / T _A ) (3)
Will be calculated and set.
