[0003] Therefore, the user sends a transmission request for the necessary information to the web server as well as the browser power on the client, and the web server sends an HTML (HyperText Markup Language) file based on the transmission request sent to the user. A method for dynamically generating an HTML file is disclosed in which information required by a user is selected and processed, and an HTML file is dynamically created for each user and sent to the browser (for example, Patent Document 1).

[0004] With this dynamic HTML file generation method, in order to create content that is easy for the user to use, the web server displays search conditions and search results for the data that the user needs based on the user's request. The condition setting screen for the method is sent, and the user sets the conditions accordingly and sends the condition setting screen to the web server. The web server receives the condition setting screen, analyzes the search condition and display method, converts it to SQL, searches the HTML file with the received search condition, and displays the detected information requested by the user. It can be configured to create a cached HTML file that is processed into a format, embedded with the processing information, and sent to the browser.

Patent Document 1: Japanese Patent Laid-Open No. 11-39329 [0005] However, in the method disclosed in Patent Document 1 above, information about users is collected and stored by many web servers on the net, and user information is stored in many web sanos on the net.

Instead of a client that cannot directly connect to the net, a proxy server that searches the net in response to a request from the client's web browser and provides the search result to the web browser may be used.

FIG. 5 is a schematic diagram showing a procedure for providing content to the client by the server according to the first embodiment, and FIG. 6 is a flowchart showing an operation of the server according to the first embodiment.

[0069] FIGS. 5 and 6 show the operation of the server 10 when the user operates the web browser 61 of the client 60 (see FIG. 3) to access the server 10 and receive a mail magazine. ing.

[0070] On the server 10 of the first embodiment, content to be provided to the user is created in advance, and is stored in the storage unit 11 (see FIG. 4) in the form of a web source 41 as shown in FIG. It is remembered.

[0071] This web source 41 is written in HTML. As shown in the figure, the comment lines 41a, 41b, 41c, 41d and the comment lines 41i, 41j, 41k , 411 Includes a powerful comment field.

[0072] In the present embodiment, change information ("!-") For changing the content to be changed by the changing unit 14 (see FIG. 4) is stored in each comment field (comment line 41a, 41b, 41c, 41d, and 41i, 41j, 41k, 411), and the change unit 14 is configured to change the content by removing the change information embedded in this comment field from the comment. ing. [0073] As shown in FIG. 5, on the screen 61 of the user-powered client, for example, a mail browser such as “Outlook (registered trademark)” (a web browser specialized for sending and receiving mail) is started, and the mail is started. If you click on the link where the necessary information is displayed for the user, the mail browser will contact the server 10 that provides the mail magazine. URL66 including the parameter corresponding to the clicked link part is transmitted.

FIG. 5 shows a URL 66 “/http:ZZZwww.hoge.fj.com/docs/man.html?mail 1001”! /. The parameter “maill001” below “?” In the URL 66 corresponds to the feature information in this embodiment.

[0075] As shown in FIG. 6, when the receiving unit 12 of the server 10 (see FIG. 4) receives the URL 66 sent from the client (step S01), the extracting unit 13 includes the feature information in the URL 66. It is determined whether or not there exists a parameter (step S02).

[0076] In step S02, if there is no parameter serving as feature information in the URL received from the client, the process proceeds to step S03, the content corresponding to the received URL is read from the one-line storage unit, and the last power of the content is read. Determine whether or not. If the read content is the last, the process is terminated (step S04). If not, the content is sent to the client as it is (step S05).

[0077] On the other hand, in step S02, if there is a parameter serving as feature information in the URL received from the client, the process proceeds to step S06, and the parameter is recorded in a predetermined storage location.

Next, one line is read from the storage unit (step S07), and it is determined whether or not the read line is the last content, and if it is the last, the process is terminated (step S08). . On the other hand, if the read line is not the last, it is determined whether or not the read content is a “start” line whose “MilMagazine NoJ (email magazine number) matches the above“ 1001 ”(Step 1). S09).

If the result of determination in step S09 is that the line whose memory capacity has also been read is a “start” line that matches “1001”, the process proceeds to step S10.

[0080] On the other hand, as a result of the determination in step S09, the read line of the memory unit power matches "1001". If it is not a matching “start” line! /, Go to step S11.

In step S10, after the variable StartFLAG for controlling content editing is set to “ON”, the process proceeds to step S16.

[0082] In step S11, it is determined whether or not the read content has an “end” line in which “MailMagazine No” (mail magazine number) matches “1001” (step Sl l). ).

If the result of determination in step SI 1 is that there is an “end” line that matches “1001”, the process proceeds to step S12, the variable StartFLAG is set to “OFF”, and then the process proceeds to step S16.

[0084] On the other hand, if the result of determination in step S11 is that there is no "end" line that matches "1001", the process proceeds to step S13, where it is determined whether or not the variable StartFLAG is "ON". (Step S13).

As a result of the determination in step S13, if the variable StartFLAG is not “ON”, the process proceeds to step S16.

On the other hand, if the result of the determination in step S 13 is that the variable StartFLAG is “ON”, the process proceeds to step S 14. In step S14, it is determined whether or not the read content is a comment line.

If the result of determination in step S14 is not a content content comment line that has been read, processing proceeds to step S16.

On the other hand, as a result of the determination in step S14, if the read content is a comment line, the content is uncommented, that is, “! Ichi” indicating that it is a comment is deleted (step S15). Thereafter, the process proceeds to step S16.

In step S16, the content is transmitted to the client (step S16), the process returns to step S06, and the processes after step S06 are repeated.

A case where the above processing is executed for the web source 41 shown in FIG. 5 will be described.

[0090] In step S01, URL 66 is received, and in step S02, the parameter "maill001" following "?" Is extracted from URL 66. Next, it is recorded in the parameter taka memory in step S06. [0091] In step S07, one line of content 41a corresponding to the received URL 66 is read. Since the content 4 la is not at the end of the content at the start of reading the content 41, it is determined at step S08 that it is not at the end of the content! /, And the process proceeds to step S09. As a result of the determination in step S09, “1 ^ & 111 ^ & ₈ & 2 ^ 16 NoJ (e-mail magazine number)“ 1001 ”in the content 41 & matches“ 1 001 ”extracted from the received URL66. Since it is a line, the process proceeds to step S10, the variable StartFLAG is set to “ON”, and then the process proceeds to step S16. In step S16, the content 41a is transmitted to the client as it is, and becomes the content 41a of the web source 41.

Note that the variable StartFLAG is initialized to “0 FFJ” prior to the execution of the flowchart shown in FIG. 5. If the content 41a is not the top line of the web source 41, that is, the content 41a If the previous line exists and step S10 is not passed, the variable StartFLAG is “OFF” in step S12.

[0093] Next, in step S07, the content 41b as the next line is read. Since content 41b is not the end of the content! /, It is determined in step S08 and the process proceeds to step S09. As a result of the determination in step S09, since the content 41b is not a “start” line having a parameter that matches the parameter “1001” extracted from the received URL 66, the process proceeds to step S11. Subsequently, as a result of the determination in step S11, since the content 41b is not an “end” line having a parameter that matches the parameter “1001”, the process proceeds to step S13. In S13, it is determined whether or not the variable StartFLAG is “ON”. As a result of the determination, since the variable StartFLAG is “ON”, the process proceeds to Step S14. In step S14, it is determined that the read content is a comment line, and the comment of content 41b is removed, that is, “!-” Of content 41b is deleted (step S15), and the comment is deleted in step S16. Content 41b is transmitted to the client, and the content of web source 41 is 4 lb.

Next, in step S07, the content 41c that is the next line is read. Since the content 41c is not the end of the content! /, It is determined in step S08 and the process proceeds to step S09. . As a result of the determination in step S09, the content 41c is not a “start” line having a parameter that matches the parameter “1001” extracted from the URL 66. Step SI Go 1 step. Subsequently, as a result of the determination in step SI 1, the content 41 c is not an “end” line having a parameter that matches the parameter “1001”, and thus the process proceeds to step S 13. In step S13, it is determined whether or not the variable StartFLAG is “ON”. As a result of the determination, since the variable StartFLAG is “ON”, the process proceeds to step S14. In step S14, it is determined that the read content is a comment line, and the comment of the content 4lc is removed, that is, "!-" Of the content 41c is deleted (step S15). The content 41c from which is deleted is transmitted to the client, and becomes the content 41c of the web source 41.

Next, in step S07, the content 41d that is the next line is read. Since content 41d is not the end of the content! /, It is determined in step S08 and the process proceeds to step S09. . As a result of the determination in step S09, “MailMagazine NoJ (mail magazine number)“ 1001 ”in the content is not a“ start ”line having a parameter that matches the parameter“ 100 1 ”extracted from the above URL 66, so the process proceeds to step S11. move on. Subsequently, as a result of the determination in step S11, the content 41d is an “end” line having a parameter that matches the parameter “1001”, so the process proceeds to step S12. In step S12, after the variable StartFLAG is set to “OFF”, the process proceeds to step S16. In step S16, the content 41d is transmitted to the client as it is, and becomes the content 41d of the web source 41 ′.

Next, in step S07, the content 41e that is the next line is read. Since content 41e is not the end of the content! /, It is determined in step S08 and the process proceeds to step S09. . As a result of the determination in step S09, since the content 41e is not a “start” line having a parameter that matches the parameter “1001” extracted from the URL 66, the process proceeds to step S11. Subsequently, as a result of the determination in step S11, since the content 41e is not an “end” line having a parameter that matches the parameter “1001”, the process proceeds to step S13. In step S13, it is determined whether or not the variable StartFLAG is “ON”. As a result of the determination, since the variable StartFLAG is “OFF”, the process proceeds to step S16. In step S16, the content 41e is transmitted to the client as it is, and becomes the content 41e of the web source 41 ′. Next, in step S07, the content 41f that is the next line is read.

[0111] FIGS. 7 and 8 show the operation of the server 10 when the user operates the web browser 61 of the client 60 (see FIG. 3) to access the server 10 and receive web content. Has been.

[0112] On the server 10 of each embodiment of the present invention, content to be provided to the user is created in advance, and the storage unit 11 (see FIG. 4) in the form of a web source 42 as shown in FIG. Is remembered.

[0113] This web source 42 is written in HTML. As shown in the figure, comment lines starting with "! Ichi" 42a, 42b, 42c, 42d, and comment lines 42i, 42j, 42k , 421 Includes a powerful comment field. Of the web source 42, the comment lines 42b, 42c, 42e, 42f, 42g, 42h, 42j, 42k other than the comment lines 42a, 42d, 42i, 421 are the web source 41 in the first embodiment. Same as each corresponding comment line. As described above, in this embodiment, change information (“! Ichi”) for changing the content to be changed by the changing unit 14 (see FIG. 4) is displayed in each comment field (comment line). 41a, 41b, 41c, 41d, and 41i, 41j, 41k, 411), and change information from comments so that the change information embedded in the change column is reflected on the display screen. It is configured to change the content by removing it.

[0115] FIG. 9 shows the contents of the keyword database used in the present embodiment.

[0116] The keyword database 62 corresponds to an example of the correspondence table referred to in the present invention. As shown in FIG. 9, the correspondence table (keyword database 62) contains information transmitted from the client. A plurality of search keywords 62b, which are a plurality of extracted feature information extracted based on the content keywords 62a, which are standard key feature information created based on the search keywords 62b, are stored in association with each other. Has been

[0117] As shown in FIG. 7, the user starts a web browser such as “Internet Explorer (registered trademark)” on the client screen 61, and a desired web page displayed on the launched web browser. When the user clicks on a keyword representing information necessary for the user from the screen 64, the web browser sends the HTTP header data including the clicked keyword to the server that provides the web page together with the http GET command. Send to 10.

[0118] For example, if “load balancing” is clicked as a keyword, as shown in FIG. 7, “HTTP REFERER = http: // kens aku. Co. JpZsearch including a referer (REFERER: link source information)” is included. The command 67 “? q = load distribution” is sent to the server 10. HTTP header data “load distribution” below “? Q” in this command 67 corresponds to the feature information in this embodiment.

[0119] As shown in FIG. 8, when the receiving unit 12 of the server 10 (see FIG. 4) receives the command 67 sent from the client (step S21), the extracting unit 13 is characterized in the command 67. It is determined whether or not there is a referrer including information (step S22).

[0120] As a result of the determination in step S22, if there is no referrer including feature information, Proceed to step S23 to read one line of content, determine whether it is power at the end of the content, end processing if it is the last (step S24), and if it is not the last, leave the content as it is to the client. Send (step S25).

[0121] On the other hand, if there is a referrer as feature information as a result of the determination in step S22, the process proceeds to step S26, and the above keyword database 62 (see Fig. 9) is read and corresponds to feature information "load distribution". The content keyword 62 a (“LB”) that is the standardized feature information to be read is read out.

[0122] Next, one line of content is read (step S27), and it is determined whether or not it is the last of the content. If it is the last, the process ends (step S28). If not, the content is read. Whether the content is a “start” line including the content keyword 62a (“LB”) is determined (step S29).

[0123] As a result of the determination in step S29, “start” including the content keyword 62a (“: LB”) is included.

If the line is “”, the process proceeds to step S30.

[0124] On the other hand, as a result of the determination in step S29, content keyword 62a ("LB") is included.

If it's not "start" line! /, Go to step S31.

In step S30, after the variable StartFLAG is set to “ON”, the process proceeds to step S36.

In step S31, it is determined whether or not the read content includes an “end” line including the content keyword 62a (“LB”) (step S31).

[0127] If the result of determination in step S31 is an "end" line containing content keyword 62a ("LB"), the process proceeds to step S32, the variable StartFLAG is set to "ON", and then the process proceeds to step S36. .

On the other hand, if the result of determination in step S31 is not an “end” line containing content keyword 62a (“LB”), the process proceeds to step S33 to determine whether or not the variable StartFLAG is “ON”. Is performed (step S33).

As a result of the determination in step S33, if the variable StartFLAG is not “ON”, the process proceeds to step S36.

[0130] On the other hand, if the result of determination in step S33 is that the variable StartFLAG is "ON", processing proceeds to step S34. In step S34, the read content is a comment line. It is determined whether or not.

[0131] If the result of determination in step S34 is not a content content comment line that has been read, processing proceeds to step S36.

On the other hand, as a result of the determination in step S34, if the read content is a comment line, the content is uncommented, that is, “! Ichi” indicating that it is a comment is deleted (step S35). Thereafter, the process proceeds to step S36.

In step S36, the content is transmitted to the client (step S36), the process returns to step S26, and the processes in and after step S36 are repeated.

[0133] By executing the above processing for the web source 42 shown in FIG. 7, the content changed by the server (see FIG. 7) is transmitted to the client. In the web source 42 after this change, as shown in Fig. 7, the lines 42b and 42g 'between the comment lines 42a and 42d are not comment lines because "! Ichi" is deleted. ing. Similarly, in the lines 42j and 42k 'between the comment lines 42i and 421, "! Ichi" is deleted and it is no longer a comment line. As a result, “div class =“ frm—bg—red ”” and “div cl ass =“ innnerblock ”” in lines 42b and 42g, and “Zdiv” and “indiverblock” in lines 42j and 42k, The description “Zdiv” becomes valid, and the display content based on the four-line comment from line 42e to line 42h is displayed in the highlighted state surrounded by a quadrilateral on the screen 69 of the client's mail browser.

In this way, the display contents from the line 42e to the line 42h are strongly appealed to the user.

Next, a third embodiment of the server of the present invention will be described.

As shown in FIG. 4, the server according to the third embodiment includes a storage unit 11 that stores content, a reception unit 12 that receives a URL transmitted from a client, An extraction unit 13 that extracts feature information based on the transmitted information, and is received by the reception unit 12 of the content stored in the storage unit 11 according to the feature information extracted by the extraction unit 13 A change unit 14 that changes the content according to the URL according to the feature information extracted by the extraction unit 13, and a transmission unit 15 that transmits the content changed by the change unit 14 to the client. It is equipped with. In addition, the extraction unit 13 in the third embodiment performs reverse DNS lookup using the IP address of the client that transmitted the URL received by the reception unit 12 as a key, and is obtained by the reverse lookup. It is configured to extract the host Z domain name as feature information.

[0138] Further, the extraction unit 13 has a correspondence table of extracted feature information extracted based on information transmitted from the client and standardized feature information obtained by standardizing the feature information, and the feature information is displayed. Further, the extracted feature information is converted into standardized feature information, and the changing unit 14 stores the content stored in the storage unit 11 in accordance with the standardized feature information. The content according to the URL received by the receiving unit 12 is configured to be changed according to the feature information extracted by the extracting unit 13.

FIG. 10 is a schematic diagram of content provision to the client by the server of the third embodiment, FIG. 11 is a flowchart showing the operation of the server of the third embodiment, and FIG. FIG. 10 is a diagram showing an IP database used in the third embodiment.

[0140] FIGS. 10 and 11 show the operation of the server 10 when the user operates the web browser 61 of the client 60 (see FIG. 3) to access the server 10 and receive web content. ing.

[0141] On the server 10 of each embodiment of the present invention, content provided to the user is created in advance, and the storage unit 11 (see FIG. 4) in the form of the web source 43 as shown in FIG. Is remembered.

[0142] This web source 43 is written in HTML. As shown in the figure, the comment line 43a, 43b, 43c, 43d and the comment line 43i, 43j that start with "! Ichi" , 43k, 431 Includes comments. Of the web source 43, the comment lines 43b, 43c, 43e, 43f, 43g, 43h, 43j, and 43k other than the comment lines 43a, 43d, 43i, and 431 are those of the web source 41 in the first embodiment. Same as each corresponding comment line.

As described above, in the present embodiment, the content to be changed by the changing unit 14 (see FIG. 4) includes the change information (“! Ichi”) for changing the content of each comment described above. Column (Comment Line 41a, 41b, 41c, 41d, and 41i, 41j, 41k, 411), and the change section 14 force The change information embedded in this comment column is reflected on the display screen. The content is changed by removing the change information from the comment. [0144] FIG. 12 shows the contents of the IP database 63 used in the present embodiment.

[0145] The IP database 63 corresponds to an example of the correspondence table referred to in the present invention. As shown in FIG. 12, the correspondence table (IP database 63) contains information transmitted from the client. A plurality of search keywords 63b, which are a plurality of extracted feature information extracted based on the search keywords 63b, and a content keyword 63a, which is a standardized feature information created based on the search keywords 63b, are stored in association with each other. Yes.

[0146] As shown in FIG. 10, the user activates a web browser such as “Internet Explorer (registered trademark)” on the screen 61 of the client, and the desired web displayed on the activated web browser. Clicking on a keyword that represents the information necessary for the user, the web browser accesses the server 10 that provides the web page. Based on the access, the server 10 reads the U RL sent from the client (step S41).

[0147] Next, the IP address of the client is extracted from the URL (step S42).

Next, reverse DNS lookup is performed using the extracted client IP address as a key (step S 43). The ability to obtain DNS domain names based on IP addresses by performing reverse DNS lookup processing Since this DNS domain name often includes sections, that is, organization names and company names, this embodiment Then, the reverse lookup process of DNS is used to obtain the organization name and company name, and the IP database 63 (see Fig. 12) is searched using it as feature information to extract keywords that match the feature information (step S44). ).

[0149] For example, the IP address extracted in step S42 is "10. 10. 10.0", and in step S43, the host address is used as feature information by reverse lookup of the IP address "10. 10. 10. 0". / If the domain name “Se. XX. Com” is obtained, the IP database 63 (see FIG. 12) is searched using this feature information “Se. Xx. Com” as a key, and the content keyword 63a, ie sec tion, is retrieved. (Section): “SE” is obtained.

Returning to the description of the flowchart shown in FIG.

[0151] In step S45 following step S44, one line of content is read, and it is determined whether or not it is the last power of the content (step S46). If it is the last, the power to finish all processing is not the last. Proceed to step S47. [0152] In step S47, the read content is the start parameter including the content keyword 63a (“SE”), and the DNS address “10. 10. 10.0” of the client is the keyword 63a of the IP database 63. It is determined whether or not it matches.

[0153] As a result of the determination in step S47, the read content is content keyword 6

3a ("SE") start parameter and client DNS address "10. 10. 10.

If “0” matches the keyword 63a in the IP database 63, proceed to step S48.

After setting the variable StartFLAG to “ON”, proceed to step S54.

On the other hand, as a result of the determination in step S47, the read content is not the start parameter including the content keyword 63a (“SE”)! /, Or the client DNS address “10.10.10.10. ”Does not match the keyword 63a of the IP database 63, the process proceeds to step S49.

[0155] In step S49, the read content is the end parameter including the content keyword 63a (“SE”), and the DNS address “10. 10. 10.0” of the client is the keyword 63a of the IP database 63. It is determined whether or not it matches.

[0156] As a result of the determination in step S49, the read content is the end parameter including the content keyword 63a ("SE"), and the client DNS address "10. 10. 10. 0" is the keyword 63a of the IP database 63. If YES in step S50, the flow advances to step S50. After the variable StartFLAG is set to “OFF”, the flow advances to step S54.

On the other hand, as a result of the determination in step S49, the read content is not the end parameter including the content keyword 63a (“SE”)! /, Or the client DNS address “10.10.10.10. ”Does not match the keyword 63a of the IP database 63, the process proceeds to step S51.

In step S51, it is determined whether or not the variable StartFLAG is “ON”. If the result of the determination in step S51 is that the variable StartFLAG is not “ON”, the force proceeds to step S54. If the result of the determination in step S51 is that the variable StartFLAG is “ON”, the process proceeds to step S52. . In step S52, it is determined whether or not the read content is a comment line.

[0159] If the result of determination in step S52 is not a read content force comment line If the read content is a comment line as a result of determination in step S52, the comment of the content is removed, that is, “!-” Indicating that it is a comment is deleted ( Step S53). Thereafter, the process proceeds to step S54.

[0160] In step S54, the content is transmitted to the client, and the process returns to step S45.

The process after 45 is repeated.

[0161] By executing the above processing for the web source 43 shown in FIG. 10, the content changed by the server (see FIG. 10) is transmitted to the client. In the web source 43 after this change, as shown in Fig. 10, the lines 43b and 43g 'between the comment lines 43a and 43d are not comment lines because "! Ichi" is deleted. . Similarly, the lines 43j and 43k ′ between the comment lines 43 i and 431 are not comment lines because “! Ichi” is deleted.

[0162] As a result, the description "div class =" frm-bg-red, "" in line 43b, line 43g, "div clas s =" innnerblock "", and "line class in line 43j, line 43k," The description of “Zdiv” and “Zdiv” becomes valid, and the display contents based on the four-line comments from line 43e to line 43h are highlighted and surrounded by a quadrilateral. Is displayed.

[0163] In this way, the display contents from line 43e to line 43h are strongly appealed to the user.

Next, an embodiment of the content distribution program of the present invention will be described.

FIG. 13 is a schematic configuration diagram of the content distribution program of the present invention.

[0166] The content distribution program 90 is an information processing apparatus that executes a program, for example, the above-described computer 100 (see Fig. 1) connected to the client 60 via the communication line 50 (see Fig. 3). ) Installed in the hard disk 600 (see Fig. 2) and executed by the operation of the computer 100 user. The computer 100 transmits the content 20 sent from the client 60. This is a program that operates as the server 10 that transmits the content 20 corresponding to the URL 30 to the client 60 according to the requested URL 30.

[0167] As shown in Fig. 13, the content distribution program 90 has the above information processing apparatus (service). Is a program that operates as a server 10 (see FIG. 3) having a storage unit 91, a receiving unit 92, an extracting unit 93, a changing unit 94, and a transmitting unit 95. is there.

[0168] The server 10 may be a web server that searches the network in response to a transmission request from the client's web browser and provides the search result to the client. Instead, it may be a proxy server that searches the net in response to the request of the client's web browser and provides the search result to the web browser.

[0169] The storage unit 91 stores content, the reception unit 92 receives a URL transmitted from a client, and the extraction unit 93 transmits from a client. The feature information is extracted based on the information that has been transmitted, and the changing unit 94 performs the above-described content out of the content stored in the storage unit 91 according to the feature information extracted by the extracting unit 93. The content according to the URL received by the receiving unit 92 is changed according to the feature information extracted by the extracting unit 93, and the transmitting unit 95 is changed after the change by the changing unit 94. The content is sent to the client.

[0170] Here, the extraction unit 93 may extract a specific parameter of a URL as feature information, or may extract specific HTTP header data as feature information. The extraction unit 93 performs reverse DNS lookup using the IP address of the client that transmitted the URL received by the reception unit 92 as a key, and the host Z domain name obtained by the reverse lookup is used as feature information. It may be extracted as

[0171] Furthermore, the extraction unit 93 has a correspondence table of extracted feature information extracted based on information transmitted from the client and standardized feature information obtained by standardizing the feature information, and the feature information is displayed. Further, the extracted feature information is converted into standardized feature information, and the changing unit 94 stores the content stored in the storage unit according to the standardized feature information. The content corresponding to the URL received by the receiving unit may be changed according to the feature information extracted by the extracting unit.

[0172] Further, the content to be changed by the changing unit 94 is content in which change information for changing the content is embedded in a comment field, and the changing unit 94 The content may be changed by removing the change information from the comment so that the change information embedded in the comment field is reflected on the display screen.
