Description

  The present invention relates to a display control method and a display control program for confirming a link destination state of link information included in a web page when displaying a web page, and particularly according to a result of confirming the link destination state. The present invention relates to a display control method and a display control program capable of notifying a user of a link destination state.

  Conventionally, some Web pages that can be browsed via a network such as the Internet display a link for transitioning to another Web page, such as a home page of a search site. However, in general, the Web page may be deleted or moved to other places by the administrator. For this reason, the Web page including the link described above sometimes includes a link that cannot actually be changed to the link destination.

  If an attempt is made to transition to such a link destination that cannot actually be changed, an error is returned to the user as a result. This causes discomfort to the user and causes inefficiency in collecting information using the Internet.

  Therefore, in order to prevent such an event, it is checked in advance whether or not the Web page on the network can be changed, the link to the Web page that cannot be changed is deleted, and the invalid link is sent to the user. A technique for preventing the presentation is disclosed (for example, see Patent Document 1). It should be noted that the determination of whether or not a Web page can be transitioned by a conventional technique is normally performed using a status code that is responded to an access request to the Web page.

JP 2001-337773 A

  However, the status code used in the above-described conventional technology defines a large number of code values according to the state of the access destination, and in fact, even if there is a linked Web page, an error is generated. The indicated code value may be responded. For example, there is a case where a temporary network failure has occurred on a route to a Web page storage location (for example, a Web server). In this case, if the link has been deleted from the displayed web page, there is a problem that even if the network failure is resolved later, the transition to the web page cannot be made.

  The present invention has been made to solve the above-described problems caused by the prior art, and a display control method capable of notifying the user of the link destination state according to the result of checking the link destination state. And a display control program.

  In order to solve the above-described problems and achieve the object, the present invention, when displaying a Web page, confirms whether a Web page linked to a link included in the Web page exists. It is a processing program, and is included in an operation definition storage procedure for storing a notification operation for notifying a user of a link destination state in a storage device in association with each status code indicating the link destination state, and a Web page to be displayed. A link destination confirmation procedure for transmitting a link destination confirmation request for confirming the presence or absence of a linked web page for each link, and a response to the link destination confirmation request transmitted by the link destination confirmation procedure The link destination confirmation response is received, and the notification operation for the status code set in the received link destination confirmation response is performed by the process definition storage procedure. Obtained from notification operation stored in the storage device, characterized in that to perform a landing state notification procedure of notifying the state of the link destination to the user based on the acquired notification operation to the computer.

  Further, according to the present invention, in the above-described invention, the operation definition storing procedure further stores, in correspondence with each status code, whether reconfirmation of the presence or absence of a Web page is associated, and the link destination status notification procedure The reconfirmation necessity for the status code set in the link destination confirmation response is acquired from the reconfirmation necessity stored in the operation definition storing procedure, and the link destination confirmation response is obtained based on the obtained reconfirmation necessity. It is determined whether or not reconfirmation is required for the link destination that has been responded, and the link destination confirmation request is periodically retransmitted to the link destination that is determined to require reconfirmation by the link destination state notification procedure. A link destination status reconfirmation procedure, and a link destination confirmation response responding to the link destination confirmation request retransmitted by the link destination status reconfirmation procedure. If the status code set in the acknowledgment indicates that the presence of the linked web page has been confirmed, the user is notified that the linked web page has been confirmed, If the status code indicates that the presence of the linked web page could not be confirmed, the notification operation for the status code is acquired from the notification operation stored by the operation definition storage procedure, and the acquisition is performed. The computer further executes a link destination state re-notification procedure for notifying the user of the link destination state based on the notification operation performed.

  Also, in the present invention according to the above-described invention, the link destination confirmation procedure may include the link destination confirmation request transmitted after transmitting the link destination confirmation request to all links included in the Web page to be displayed. The Web page is displayed without waiting for a link destination confirmation response to be responded to.

  Further, the present invention, in the above invention, further causes the computer to execute a notification operation changing procedure for changing a notification operation for each status code stored by the operation definition storing procedure in accordance with an instruction from a user. And

  The present invention also provides a browser processing apparatus for checking whether or not a link destination web page included in a web page exists when the web page is displayed. An operation definition storage means for storing a notification operation to be notified to the user in association with each status code indicating the state of the link destination, and the presence / absence of a link destination Web page for each link included in the Web page to be displayed A link destination confirmation unit for transmitting a link destination confirmation request for confirmation; a link destination confirmation response received in response to the link destination confirmation request transmitted by the link destination confirmation unit; and the received link destination confirmation unit The notification operation for the status code set in the response is acquired from the notification operation stored by the operation definition storage means, and based on the acquired notification operation Characterized by comprising a landing state notification means for notifying the linked state to the user, the Te.

  According to the present invention, the notification operation for notifying the user of the link destination state is stored in association with each status code indicating the link destination state, and the link destination is stored for each link included in the Web page to be displayed. A link destination confirmation request for confirming the presence / absence of a Web page is transmitted, and a link destination confirmation response that is responded to the transmitted link destination confirmation request is received and set in the received link destination confirmation response The notification operation for the status code is acquired from the stored notification operation, and the link destination status is notified to the user based on the acquired notification operation. Depending on the result of checking the link destination status It is possible to perform notification operations such as link deletion and message display, and to notify the user of the link destination state appropriately.

  Further, according to the present invention, the necessity of reconfirmation of the presence / absence of the Web page is further stored for each status code, and the necessity of reconfirmation for the status code set in the received link destination confirmation response is determined. It is acquired from the stored reconfirmation necessity, and it is determined whether reconfirmation is necessary for the link destination to which the link destination confirmation response is returned based on the obtained reconfirmation necessity. A link destination confirmation request is periodically retransmitted to the determined link destination. The link destination confirmation response received in response to the retransmitted link destination confirmation request is received, and the status code set in the received link destination confirmation response indicates that the existence of the link destination web page has been confirmed. If the status code indicates that the presence of the linked web page has not been confirmed, the user is informed that the existence of the linked web page has been confirmed. Because the notification action for the status code is acquired from the stored notification action and the link destination status is notified to the user based on the acquired notification behavior, depending on the result of checking the link destination status For example, if the existence of the linked web page could not be confirmed due to the temporary link destination, the existence was confirmed and the existence was confirmed. An effect that it is possible to notify the user at the point.

  In addition, according to the present invention, after a link destination confirmation request is transmitted to all links included in the Web page to be displayed, a link destination confirmation response that is responded to the transmitted link destination confirmation request is waited. Since the web page is displayed without being displayed, it is possible to prevent the display of the web page from being delayed for confirmation of the link destination and to provide the user with a light transition between the web pages. .

  In addition, according to the present invention, the notification operation for each stored status code is configured to be changed according to an instruction from the user, so that the user can perform the notification operation of the link destination state in the network environment. There is an effect that it can be changed according to the situation and personal preference.

  Exemplary embodiments of a display control method and a display control program according to the present invention will be described below in detail with reference to the accompanying drawings. In the present embodiment, the case where the present invention is applied to a browser processing apparatus that browses Web pages via the Internet will be mainly described.

  First, the concept of the browser processing apparatus according to the present embodiment will be described. FIG. 1 is a diagram for explaining the concept of the browser processing apparatus according to the present embodiment. FIG. 3 shows a Web page displayed on the display 10 of the browser processing apparatus according to the present embodiment.

  “State 1” in FIG. 1 shows an example of a Web page including a link. The underlined items such as “PC”, “mobile phone”, “support”, etc. displayed on this Web page are defined with links to other Web pages, respectively. By using an input means such as a mouse or a keyboard, for example, the user can transition to a link destination Web page of the link defined for each.

  Before displaying the Web page shown in “state 1” on the display 10, the browser processing apparatus analyzes the content of the Web page and extracts a link included therein. Then, the browser processing apparatus transmits a link destination existence confirmation request for confirming the existence of the linked web page to the link destination of each extracted link, and then displays the web page on the display 10. .

  Here, for example, the link destination existence confirmation request sent to the link destination of the link defined in “PC” was not accepted due to temporary overload or maintenance. Assume that a link destination existence confirmation response including a status code indicating is sent back to the browser processing apparatus. In this case, the browser processing apparatus notifies the user that there is a high possibility that the link destination cannot be connected because the presence or absence of the link destination Web page cannot be confirmed.

  For example, as shown in “state 2” in FIG. 1, the browser processing apparatus displays a warning message or a pop-up in the status area 11 when the user selects “PC”. The notification operation performed here is performed based on the notification operation for each status code set by the user.

  In addition to displaying warning messages to the user, the browser processing device periodically checks the link destination of the link defined in “PC” in case the connection to the link destination is restored. Resubmit the link destination existence confirmation request. The re-transmission of the link destination existence confirmation request performed here is performed based on the necessity of re-confirmation for each status code set by the user.

  When the link destination existence confirmation response including the status code indicating that the transition to the link destination web page is possible in response to the retransmitted link destination existence confirmation request, the browser processing device The user is notified that the presence of the linked Web page has been confirmed.

  For example, as shown in “state 3” in FIG. 1, the browser processing apparatus displays a notification message or a notification icon in the status area 11. For example, when the user selects a notification icon, the browser processing apparatus displays a list of URLs (Uniform Resource Locators) indicating the locations of Web pages whose existence has been confirmed (see “Status 3” in FIG. 1). "Linked list").

  Thus, the browser processing apparatus according to the present embodiment transmits a link destination existence confirmation request for confirming the presence / absence of the link destination web page for each link included in the web page to be displayed, and The link destination existence confirmation response that is responded to the sent link destination existence confirmation request is received, and the user is notified of the link destination status according to the status code set in the received link destination existence confirmation response. According to the result of confirming the link destination status, the link destination status can be appropriately notified to the user.

  Further, the browser processing apparatus according to the present embodiment determines whether or not it is necessary to reconfirm the link destination to which the link destination existence confirmation response is responded according to the status code set in the received link destination existence confirmation response. The link destination existence confirmation request is periodically re-transmitted to the link destination that has been determined to require reconfirmation. Then, the browser processing apparatus receives the link destination existence confirmation response that is responded to the retransmitted link destination existence confirmation request, and the status code set in the received link destination existence confirmation response is the link destination Web page. If it indicates that the existence has been confirmed, the user is notified that the existence of the linked web page has been confirmed. Therefore, depending on the result of confirming the link destination status, for example, the link destination is When the existence of the linked Web page cannot be confirmed for a temporary reason, it is possible to continue the existence confirmation and notify the user when the existence is confirmed.

  Next, the configuration of the browser processing apparatus according to the present embodiment will be described. FIG. 2 is a functional block diagram illustrating the configuration of the browser processing apparatus according to the present embodiment. As shown in the figure, in response to a request from a user, the browser processing apparatus 100 acquires various Web pages from another computer such as a Web server via the Internet 200, and displays the acquired Web pages. 10 and the like.

  The browser processing apparatus 100 includes functions that are closely related to the present invention, such as a request transmission unit 110, a response reception unit 120, a processing definition list 130, a content analysis unit 140, a link destination URL list 150, An automatic reconfirmation unit 160, an automatic reconfirmation target URL list 170, and a customization processing unit 180 are included.

  The request transmission unit 110 is a processing unit that transmits a request to another computer via the Internet 200. For example, the request transmission unit 110 transmits a link destination existence confirmation request for confirming the existence of a linked web page.

  The response receiving unit 120 is a processing unit that receives a response from another computer via the Internet 200. For example, the response receiving unit 120 receives a link destination existence confirmation response that is responded to the above-described link destination existence confirmation request.

  The process definition list 130 is a storage unit that stores various setting information regarding processes performed by the browser processing apparatus 100. 3 and 4 are a diagram (1) showing an example of various setting information stored by the process definition list 130 and a diagram (2) showing an example of various setting information stored by the process definition list 130. The various setting information shown in both figures is set and changed by the customization processing unit 180 in accordance with an instruction from the user.

  The “link destination confirmation implementation / non-execution setting” shown in FIG. 3 is setting information for selecting whether to perform link destination confirmation processing by the content analysis unit 140 and link destination reconfirmation processing by the automatic reconfirmation unit 160. For example, as shown in the figure, either “Yes” or “No” is set.

  In addition, “Link destination status pattern setting for status code” shown in the figure is a link destination indicating a notification operation to the user when each status code is received for each status code included in the link destination existence confirmation response. This is setting information associated with a state notification pattern. As the status code here, for example, as shown in the figure, an HTTP (HyperText Transfer Protocol) status code defined by RFC 2068 of the Internet Research Task Force (IETF) is set.

  In the link destination state notification pattern, for example, “◯”, “Δ”, and “X” are set for each status code as shown in FIG. “○” indicates a pattern in which a transition to a linked web page is expected to be successful, and a transition operation is performed as usual, “Δ” indicates a pattern that may fail if a transition operation is performed, and “×” indicates that The patterns that fail reliably even when the transition operation is performed are shown (see “Pattern classification” in “Operation setting of link destination state pattern”).

  The link destination state notification pattern is associated with an operation setting number indicating the type of notification operation to the user for each link destination state notification pattern, as shown in “Operation setting of link destination state pattern” shown in FIG. It has been.

  This operation setting number indicates the operation content of the notification to the user. For example, “1”, “2”, “3”, “operation content of link destination state pattern” shown in FIG. “4” and “5” are set. Here, “1” indicates that nothing is performed, “2” indicates that the link is deleted, and “3” indicates that when the mouse passes over an anchor (an item for which a link is defined). To display a popup, “4” indicates that a message is displayed in the status area 11 in a state where the anchor is focused, “5” indicates that the focus frame is changed while the anchor is focused, Each is shown.

  Such setting of the operation content is realized, for example, by changing the HTML of the Web page using DOM (Document Object Model). Specifically, the operation whose operation content is “2” is realized by deleting the href attribute of the a element. For the operation with the operation content “3”, a p element for displaying a popup is added, an unusualover attribute and an unusualout attribute are added to the a element, and a script that describes a script for switching the visibility attribute of the p element is described. Realized by adding elements. Also, the element whose operation content is “4” is realized by adding an unusualover attribute and an unusualoutout attribute to the a element, and further adding a script element describing a script for displaying a message in the status area 11.

  In addition, “display / non-display setting for display during presence check” illustrated in FIG. 4 is setting information for selecting display / non-display of the display during presence check by the content analysis unit 140, for example, as illustrated in FIG. Thus, either “present (display)” or “not present (non-display)” is set. When the presence confirmation display is set to “present”, the content analysis unit 140 performs a notification operation of the presence confirmation display.

  Further, “link destination automatic reconfirmation execution / non-execution setting” shown in the figure is setting information for selecting execution / non-execution of link destination reconfirmation processing by the automatic reconfirmation unit 160. As shown in the figure, either “Yes” or “No” is set.

  Also, "Automatic reconfirmation operation setting for status code" shown in the figure is the setting information that associates the automatic reconfirmation operation performed when each status code is received for each status code included in the link destination existence confirmation response. It is.

  Here, in the automatic reconfirmation operation, for example, “◯” and “X” are set for each status code as shown in FIG. “○” indicates that the link destination of the link destination existence confirmation response including the status code is subject to automatic reconfirmation, and “×” indicates that it is not subject to automatic reconfirmation (same as above). (Refer to “Operation details of automatic reconfirmation operation”).

  Further, “automatic reconfirmation interval setting” shown in the figure is setting information for setting the transmission interval of the link destination existence confirmation request by the automatic reconfirmation unit 160. For this transmission interval, an arbitrary time determined by the user is set. For example, “15 seconds” is set as shown in FIG.

  The content analysis unit 140 transmits a link destination existence confirmation request for confirming the existence of the link destination web page to the link destination of the link information included in the web page to be displayed. In response to the status code included in the link destination existence confirmation response, the processing unit notifies the user of the link destination state.

  The content analysis unit 140 operates when setting for performing link destination confirmation is performed in the setting information of “link destination confirmation execution / non-execution setting” stored in the process definition list 130. Specifically, the content analysis unit 140 first analyzes HTML (HyperText Markup Language) of a Web page acquired from another computer in response to a request from the user, and sequentially describes a elements described therein. Check. Then, the content analysis unit 140 sequentially transmits a link destination existence confirmation request to the URLs specified in the href attribute of the a element, and stores the URLs in the link destination URL list 150.

  Using this link destination URL list 150, the content analysis unit 140 manages whether or not a link destination existence confirmation response has been received for each URL for which a link destination existence confirmation request has been transmitted.

  When the link destination existence confirmation request is transmitted to the URLs set in the href attribute of all the a elements, the content analysis unit 140 outputs a Web page to output means such as the display 10.

  Here, after the content analysis unit 140 transmits the link destination existence confirmation request to all the links included in the Web page to be displayed, the link destination existence that is responded to the transmitted link destination existence confirmation request By displaying the Web page without waiting for the confirmation response, it is possible to prevent the display of the Web page from being delayed for link destination confirmation and to provide the user with a light transition between the Web pages.

  When outputting the web page, the content analysis unit 140 displays “existence” when “present” is selected in the setting information of “display / non-display setting of display during existence confirmation” stored in the process definition list 130. Based on the setting information of “operation content displayed during confirmation”, a setting is made to notify the user that the existence is being confirmed. For example, the content analysis unit 140 is configured to display a message indicating that the presence is being confirmed in the status area 11 while the anchor that is transmitting the link destination existence confirmation request is focused.

  Then, when receiving the link destination existence confirmation response that is responded to the transmitted link destination existence confirmation request, the content analysis unit 140 displays the link destination state corresponding to the status code included in the received link destination existence confirmation response The notification pattern is acquired from the setting information of “link destination state pattern setting for status code” in the process definition list 130. Subsequently, the content analysis unit 140 acquires an operation setting number corresponding to the acquired link destination information notification pattern from the setting information of “operation setting of link destination state pattern”, and based on the operation content indicated by the acquired operation setting number To notify the user of the status of the link destination.

  For example, if the process definition list 130 stores the setting information of the example shown in FIG. 3, the content analysis unit 140 receives the status code “504 (gateway timeout)” and the link destination state Since the notification pattern is “◯”, no notification operation is performed to the user, and when the status code “500 (server internal error)” is received, the link destination state notification pattern is “Δ”. When the mouse passes over the anchor, a pop-up is displayed, and when “400 (illegal request)” is received, the link destination state notification pattern is “×”. Displays a pop-up when the mouse passes over

  The message displayed in the pop-up here is set in advance according to the operation content. For example, if the link is deleted, "Link deleted" is set, and if the link is not deleted "It is highly possible that the link destination cannot be connected" is set.

  Also, the content analysis unit 140 acquires the automatic reconfirmation operation corresponding to the status code included in the received link destination existence confirmation response from the setting information of “automatic reconfirmation operation setting for status code”, and If a value indicating that the link destination is to be automatically confirmed is set in the reconfirmation operation (“◯” in the example of FIG. 4), the URL included in the link destination existence confirmation response is automatically reconfirmed URL Store in list 170.

  The link destination URL list 150 is a storage unit that stores the link destination confirmation URL extracted by the content analysis unit 140.

  The automatic reconfirmation unit 160 periodically transmits a link destination existence confirmation request to the URL stored in the automatic reconfirmation target URL list 170, and the link destination responded to the transmitted link destination existence confirmation request. The processing unit notifies the user of the link destination state according to the status code included in the presence confirmation response.

  This automatic reconfirmation unit 160, when “link destination automatic reconfirmation execution / non-execution setting” stored in the process definition list 130 is set to perform automatic link destination reconfirmation, It operates at the time interval set in the setting information of “confirmation interval setting”. Specifically, the automatic reconfirmation unit 160 first sequentially transmits a link destination existence confirmation request to the URLs stored in the automatic reconfirmation target URL list 170, and the URL to which the link destination existence confirmation request is transmitted is Delete from automatic reconfirmation control URL.

  When the automatic reconfirmation unit 160 receives a link destination existence confirmation response that is responded to the transmitted link destination existence confirmation request, the link destination corresponding to the status code included in the received link destination existence confirmation response The state notification pattern is acquired from the setting information of “link destination state pattern setting for status code” in the process definition list 130.

  Here, when the acquired link destination information notification pattern is a pattern for performing a transition operation as usual (“◯” in the example of FIG. 3), the automatic reconfirmation unit 160 uses a predetermined method to inform the user. It notifies that the existence of the linked Web page has been confirmed.

  For example, as shown in “state 3” in FIG. 2, a notification message or a notification icon is displayed in the status area 11. For example, when the user selects a notification icon, a URL (Uniform Resource Locator) indicating the location of a Web page whose existence has been confirmed, as shown in “link destination list” shown in “state 3” in FIG. List. Further, when the user selects the URL displayed in the list here, the user may be notified of the link whose existence has been confirmed by changing the display color of the anchor corresponding to the URL.

  On the other hand, if the acquired link destination information notification pattern is a pattern that does not perform a transition operation as usual (“Δ” or “×” in the example of FIG. 3), the automatic reconfirmation unit 160 acquires the acquired link destination. The operation setting number corresponding to the information notification pattern is acquired from the setting information of “operation setting of link destination state pattern”, and the link destination state is notified to the user based on the operation content indicated by the acquired operation setting number.

  For example, if the process definition list 130 stores the setting information of the example shown in FIG. 3, the automatic reconfirmation unit 160 receives the status code “500 (server internal error)” and the link destination Since the status notification pattern is “△”, a pop-up is displayed when the mouse passes over the anchor, and when “400 (illegal request)” is received, the link destination status notification pattern is “x”. After deleting the link, a popup is displayed when the mouse passes over the anchor.

  Here, the message to be displayed in the pop-up is set in advance according to the operation content. For example, if the link is deleted, "Link deleted" is set, and the link is not deleted Is set such as "It is highly possible that the link destination cannot be connected".

  Further, the automatic reconfirmation unit 160 acquires the automatic reconfirmation operation corresponding to the status code included in the received link destination existence confirmation response from the setting information of “automatic reconfirmation operation setting for status code”, and acquires the automatic reconfirmation operation. If a value indicating that the link destination is subject to automatic confirmation is set in the automatic reconfirmation operation ("○" in the example of FIG. 4), the URL included in the link destination existence confirmation response is subject to automatic reconfirmation. Stored in the URL list 170.

  The automatic reconfirmation target URL list 170 is a storage unit that stores automatic reconfirmation target URLs output by the content analysis unit 140 and the automatic reconfirmation unit 160.

  The customization processing unit 180 is a processing unit that changes various setting information stored in the processing definition list 130 in accordance with an instruction from the user. For example, in accordance with an instruction from the user, the customization processing unit 180 changes the setting of link destination confirmation execution / non-execution, changes the association between the status code and the link destination state notification pattern, Change the association between status code and reconfirmation action.

  In this way, the customization processing unit 180 changes various setting information stored in the process definition list 130 such as a link destination state notification pattern and a reconfirmation operation for each status based on an instruction from the user. The user changes the link destination status notification operation, the necessity of re-checking the link destination status, and the link destination check execution / non-execution setting according to the network environment status and personal preference. be able to.

  Next, the operation of the browser processing apparatus 100 according to the present embodiment will be described. FIG. 5 is a flowchart illustrating the processing procedure of the browser processing apparatus 100 according to the present embodiment. In the following, a case will be described in which the various setting information of FIGS. 3 and 4 is stored in the process definition list 130.

  When “Yes” is selected in the setting information of “link destination check execution / non-execution setting” stored in the process definition list 130, the browser processing apparatus 100 first displays the content as shown in FIG. The analysis unit 140 performs content reading processing (step S101). This content reading process will be described later with reference to FIG.

  Then, the content analysis unit 140 receives a link destination existence confirmation response to the link destination existence confirmation request transmitted in the content reading process, or timed out (link destination existence confirmation even if a predetermined waiting time has elapsed). If no response has been received (step S102, Yes), link destination existence confirmation response reception processing is performed (step S103). This link destination existence confirmation response reception process will be described later with reference to FIG.

  While there is a link destination existence confirmation request that has not received the link destination existence confirmation response (Yes in step S104), the content analysis unit 140 repeats the processes in steps S102 and S103 described above.

  Then, after the link destination existence confirmation response is responded to all the link destination existence confirmation requests transmitted by the content analysis unit 140, the automatic reconfirmation unit 160 stores the “link destination automatic confirmation” stored in the process definition list 130. When “Yes” is selected in the setting information of “execution / non-execution setting of reconfirmation” and the automatic reconfirmation transmission cycle times out (“automatic reconfirmation interval setting stored in process definition list 130”). ”(When the time set in the setting information has elapsed) (step S105, Yes), an automatic reconfirmation transmission process is performed (step S106). This automatic reconfirmation transmission process will be described later with reference to FIG.

  Then, the automatic reconfirmation unit 160 receives a link destination existence confirmation response to the link destination existence confirmation request transmitted in the automatic reconfirmation transmission process, or times out (the link is not received even after a predetermined waiting time elapses). If the pre-existence confirmation response has not been received (step S107, Yes), automatic reconfirmation response reception processing is performed (step S108). This automatic reconfirmation response process will be described later with reference to FIG.

  The automatic reconfirmation unit 160 repeats the processes of steps S107 and S108 as long as there is a link destination existence confirmation request that has not received the link destination existence confirmation response (step S109, Yes).

  Next, the processing procedure of the content reading process shown in FIG. 5 will be described. This content reading process is performed by the content analysis unit 140. FIG. 6 is a flowchart showing a processing procedure of the content reading process shown in FIG.

  As shown in the figure, the content analysis unit 140 first checks the elements described in the HTML of the Web page acquired from another computer in order (step S201), and if it is an a element (step S202). , Yes), it is confirmed whether or not the href attribute is designated. If the href attribute is specified (step S203, Yes), the content analysis unit 140 asynchronously transmits a link destination existence confirmation request to the URL specified in the href attribute (step S204). The URL is stored in the link destination URL list 150.

  Subsequently, when “present” is selected in the setting information of “display / non-display setting of display during existence confirmation” stored in the process definition list 130, the content analysis unit 140 displays “display during existence confirmation”. Based on the “operation contents”, a setting is made to notify the user that the existence is being confirmed for each anchor (step S205).

  The content analysis unit 140 returns to step S202 and repeats the processes of subsequent steps S202 to S205 while there is an element that has not been confirmed yet in the elements described in HTML (step S206, Yes). When all elements described in the HTML are confirmed (step S206, No), the content analysis unit 140 outputs the Web page to an output unit such as the display 10 (step S207), and ends the content reading process. To do.

  Next, the processing procedure of the link destination existence confirmation response reception process shown in FIG. 5 will be described. This link destination existence confirmation response reception process is performed by the content analysis unit 140. FIG. 7 is a flowchart showing a processing procedure of the link destination existence confirmation response receiving process shown in FIG.
