Description

  The present invention relates to a web page generation system and a web page generation method including a first server that generates a web page requested by a user and a second server that can communicate with the plurality of first servers, and in particular, access. The present invention relates to a web page generation system and a web page generation method capable of reducing wasteful costs while ensuring processing capability capable of coping with concentration of the user.

  In general, a web page viewed from a client terminal connected to the Internet is generated by a web server. When the web server receives a web page browsing request from the client terminal, the web server generates a designated web page and distributes the page data to the client terminal. At this time, the web server obtains information to be displayed on the designated web page from a database or the like, and arranges the obtained information in a template to generate a web page.

  However, since such a web page generation process takes a relatively long time, if the web page generation process is performed every time in response to a browsing request from the client terminal, the response to the client terminal tends to be delayed. Therefore, the web server temporarily stores the generated web page as a cache, and when there is a browsing request for the same page, the page data of the cached web page is transmitted to the client terminal. Yes. Thereby, about the web page once produced | generated, the response to a client terminal is accelerated.

  Furthermore, for example, in Patent Document 1, information displayed on a web page is partially cached, and when there is a browsing request for the same page, the cached information and newly acquired information are arranged. And generating a web page. According to the technique disclosed in Patent Document 1, even in the case of a web page including information that changes each time it is displayed, such as a term search, a portion that does not change can be quickly transferred to a client terminal using cached information. A web page can be provided, and the memory consumption of the web server can be reduced.

JP 2004-13345 A

  However, even if the memory consumption is reduced by the cache, access to the web page may be biased in time, so a large amount of memory can be installed in the web server to withstand the peak of access, There is a need to increase the number of web servers, and there is a problem that wasteful costs occur due to over-specification at normal times.

  That is, for example, when a typhoon approaches, access may be concentrated on web pages such as a weather forecast site or a public transportation operation information site. In addition, it is considered that access to the web page of a site that provides event-related information is concentrated before and after the actual event. Also, depending on the time of the day, the time at which access reaches a peak varies from site to site. In such sites, the memory size and the number of web servers are determined based on the peak of access so that web pages can be provided even when access is concentrated. A part of the web server becomes a wasteful resource.

  The present invention has been made in view of the above points, and a web page generation system, a web page generation apparatus, and a web page generation method capable of reducing wasteful costs while ensuring processing capability capable of dealing with concentration of access.

  Further, the present invention is a web page generation program for generating a web page requested by a user, and is necessary for a reception procedure for receiving a web page browsing request from the user and for generating a web page for which the user requests browsing. A search procedure for searching for partial information from a memory that temporarily stores partial information constituting a web page generated in the past, and generation for generating a web page using the partial information searched in the search procedure It is characterized by causing a computer to execute a procedure, a reporting procedure for reporting a storage status of partial information in the memory to an external device, and a receiving procedure for receiving a partial information duplication instruction from the external device.

  Further, the present invention is a partial information management program for managing partial information temporarily stored in a web page generating device that generates a web page from partial information constituting a web page, and is reported from the web page generating device. A determination procedure for determining whether or not to copy partial information from one web page generation device to another web page generation device with reference to a management table for managing the storage status of partial information, According to the result, the computer is caused to execute a transmission procedure for transmitting a partial information duplication instruction to at least one web page generation apparatus.

  According to the present invention, the first server temporarily stores, as a unit, partial information constituting the web page for a web page generated in the past, receives a request for browsing the web page from the user, When the partial information necessary for generating the web page requesting browsing is searched from the stored partial information, and the necessary partial information is not stored as a result of the search, the partial server generates the partial information. To generate a web page using the searched partial information and the partial information requested to be generated, and the second server generates the partial information requested from the first server, and the generated part Information is provided to the first server. For this reason, for the parts common to web pages generated in the past, the partial information stored in the first server is used to generate web pages, reducing the processing load of partial information generation by the second server. can do. For the access peak, it is only necessary to adjust the number of general-purpose first servers. Even if the access peak to a certain site converges, the surplus first server is replaced by another site. It can be used to generate a web page, and wasteful costs can be reduced while ensuring a processing capability that can cope with concentration of access.

  In addition, according to the present invention, the first server temporarily stores the partial information provided from the second server, so that the partial information once used for generating the web page is cached. It is not necessary to generate partial information that is used repeatedly for the second time and later, and the processing load on the second server can be efficiently reduced.

  According to the present invention, since the first server stores only static part information that has not changed over a predetermined period, personalized part information including frequently changing dynamic part information and user-specific information is generated every time. Thus, a web page that is always up-to-date and according to the user can be generated.

  Further, according to the present invention, the first server temporarily stores web page templates generated in the past, so it is necessary to acquire a relatively recently generated web page template from the second server. The processing load on the second server can be further reduced.

  According to the present invention, since the first server generates a web page by incorporating partial information into a template for each web page, web page generation processing is facilitated, and the processing load on the first server is reduced. can do.

  Further, according to the present invention, the second server simultaneously generates partial information that can be replaced with the partial information requested from the first server, so that, for example, the site provider promotes an increase in the number of browsing. For the replaceable partial information including a link to a web page or an advertisement, a plurality of pieces of partial information are cached together in the first server, and partial information generation from the first server to the second server is performed. The number of requests can be reduced.

  According to the present invention, the first server temporarily stores, in units of partial information constituting the web page, a web page generated in the past, and accepts a request for browsing the web page from the user. The partial information necessary for generating the web page that the user requests to browse is searched from the stored partial information, the web page is generated using the searched partial information, and the storage status of the partial information is stored in the second server. The second server copies the partial information from one first server to another first server with reference to the management table that manages the storage status of the partial information reported from the first server. It is determined whether or not to do so, and a partial information duplication instruction is transmitted to at least one first server according to the determination result. For this reason, since the partial information is replicated among the plurality of first servers according to the storage status of the partial information in the first server, the master server that generates the partial information further reduces the generation of partial information. The processing load on the server can be further reduced.

  According to the present invention, the first server reports the number of times the partial information is used to the second server, and the second server is the partial information for which the number of times used recorded in the management table reaches a predetermined number. Is determined to be copied, and as a result of the determination, a copy instruction of partial information whose number of uses has reached a predetermined number is transmitted. Therefore, even partial information that has never been used to generate a web page in the first server can be cached with partial information that is frequently used in the other first servers.

  According to the present invention, the second server transmits a partial information duplication instruction to all the first servers that do not store the partial information. Can be cached on any server.

  Further, according to the present invention, when the first server receives the copy instruction transmitted from the second server, the first server copies the partial information to the first server that stores the partial information related to the copy instruction. Request. For this reason, it is possible to request and cache the copy of the partial information by the same process as when the generation of the partial information is requested to the master server.

  Further, according to the present invention, the second server adjusts the duplication schedule based on the processing load of the first server, so the processing load of the first server that is the duplication source and duplication destination of the partial information is excessive. Therefore, necessary partial information can be reliably cached in the first server.

  Further, according to the present invention, when the necessary partial information is not stored as a result of the search, the first server shares the partial information with the other first server to the second server. When the requested partial information is stored in at least one first server, the second server determines that the partial information is to be duplicated, and duplicates the partial information requested to be shared. An instruction is transmitted to the first server that requested the sharing of the partial information. For this reason, even partial information that has never been used to generate a web page in the first server can be cached in partial information cached in another first server.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(Embodiment 1)
FIG. 1 is a diagram showing an overall configuration of a web page generation system according to Embodiment 1 of the present invention. In this web page generation system, when a web page browsing request (hereinafter referred to as “page request”) is transmitted from the client terminal 1, the page request is transmitted to the load balancer 3-1 or the load balancer via the network 2 such as the Internet. It is received at 3-2. The distribution to the load balancers 3-1, 3-2 is executed by a method such as DNS (Domain Name System) round robin.

  The load balancers 3-1 and 3-2 that have received the page request generate a requested web page in consideration of the load status and processing capability of the general-purpose web server 100 connected to the self-device. The web server 100 is selected, and the page request is transferred to the selected general-purpose web server 100.

  The general-purpose web server 100 checks whether or not the template that is the framework of the web page requested by the page request is cached. If not, the master server 4-1 or the master server 4 connected to its own device. Request a template to -2. Then, the general-purpose web server 100 checks whether or not the information module to be incorporated in the template obtained from the cache or the master server 4-1 or 4-2 is cached. Request a module from the master server 4-2. Here, the module is a piece of information constituting a part of a web page. Specifically, one web page is composed of a plurality of modules such as a title portion of a web page and a news headline portion.

  When the requested web page template and module are prepared, the general-purpose web server 100 generates a web page and transmits the page data to the client terminal 1. Further, the templates and modules acquired from the master servers 4-1 and 4-2 are cached.

  When receiving a template request for requesting a template or a module request for requesting a module from the general-purpose web server 100, the master servers 4-1 and 4-2 return the requested template or module. When the module request is received, the master servers 4-1 and 4-2 acquire information necessary for generating the modules from the application servers 5-1 to 5-4, generate the modules, and the general-purpose web server 100. Reply to

  In the application servers 5-1 to 5-4, information necessary for module generation is generated. Each of the application servers 5-1 to 5-4 is operated by a different application, and generates various information according to the generated module. Specifically, the application servers 5-1 to 5-4, for example, static information such as titles that do not change for a relatively long period of time, dynamic information such as frequently updated news, and page requests User-specific personalized information and the like that differ for each client terminal 1 of the transmission source is generated. A database (not shown) or the like may be connected to these application servers 5-1 to 5-4.

  Note that the configuration of the web page generation system illustrated in FIG. 1 is an example, and the number of devices, connection relationships, and the like are not limited to those illustrated in FIG. However, the general-purpose web server 100 that caches templates and modules is separated from the master servers 4-1 and 4-2 that actually generate modules.

  FIG. 2 is a block diagram showing an internal configuration of the general-purpose web server 100 according to the present embodiment. A general-purpose web server 100 shown in FIG. 2 includes a request reception unit 101, a template cache search unit (hereinafter abbreviated as “T cache search unit”) 102, a storage unit 103, a module cache search unit (hereinafter referred to as “M cache search unit”). (Abbreviated) 104, request issuing unit 105, information acquisition unit 106, cache registration unit 107, page generation unit 108, and page transmission unit 109.

  The request reception unit 101 receives a page request (indicated as “page REQ” in FIG. 2) transmitted from the client terminal 1, and notifies the T cache search unit 102 of information on the requested web page.

  The T cache search unit 102 searches the template of the requested web page from the template cached in the storage unit 103. If this template is cached, the template is output to the M cache search unit 104 and must be cached. If so, the request issuing unit 105 is notified.

  The storage unit 103 stores a template or a module used for generating a web page as a cache. Then, the storage unit 103 deletes templates and modules that are not used for a certain period of time. The valid time until the template or module is deleted is defined in advance for each template or module. FIG. 2 shows a state in which the storage unit 103 caches the template 01 and the module 01 as an example.

  The M cache search unit 104 searches the module cached in the storage unit 103 for a module to be incorporated into the template output from the T cache search unit 104 or the page generation unit 108. If this module is cached, the M cache search unit 104 searches for the module. The data is output to the page generation unit 108, and if it is not cached, the request issuance unit 105 is notified accordingly. Note that the M cache search unit 104 searches the storage unit 103 for all modules even when there are a plurality of modules to be incorporated into the template.

  When the request issuing unit 105 is notified from the T cache search unit 102 that the template is not cached, the master server to which the template request (indicated as “template REQ” in FIG. 2) for requesting this template is connected. 4-1 or the master server 4-2 (hereinafter referred to as “master server 4”). Further, when the request issuing unit 105 is notified from the M cache search unit 104 that the module is not cached, the request issuing unit 105 sends a module request (denoted as “module REQ” in FIG. 2) requesting this module to the master server 4. Send.

  The information acquisition unit 106 receives the template and module returned from the master server 4 in response to the template request and the module request, and outputs them to the cache registration unit 107 and the page generation unit 108.

  The cache registration unit 107 caches the template and module output from the information acquisition unit 106 in the storage unit 103. However, if the module output from the information acquisition unit 106 is a dynamic module that changes frequently or is a personalized module that includes user-specific information, the cache registration unit 107 discards this module, The storage unit 103 is not cached. In other words, the cache registration unit 107 caches a static module that does not change over a predetermined period in the storage unit 103.

  The T cache search unit 102, the M cache search unit 104, and the cache registration unit 107 described above form a cache control unit that performs control related to the cache of templates and modules.

  The page generation unit 108 generates a web page requested from the client terminal 1 using a template and a module that have been cached in the storage unit 103 or acquired by the information acquisition unit 106. Specifically, for example, as illustrated in FIG. 3, the page generation unit 108 generates a web page by incorporating a module 01 or the like in each frame of the template 01.

  The page transmission unit 109 transmits the page data of the web page generated by the page generation unit 108 to the client terminal 1 via the network 2.

  Next, the operation of the general-purpose web server 100 configured as described above will be described with reference to the flowchart shown in FIG.

  The page request transmitted from the client terminal 1 is received by the request receiving unit 101 of the general-purpose web server 100 via the network 2 and the load balancers 3-1, 3-2 (step S101). When the page request is accepted, the T cache search unit 102 searches whether the requested web page template is cached in the storage unit 103 (step S102). If the template is cached in the storage unit 103, the template is read and output to the M cache search unit 104.

  On the other hand, if the template is not cached in the storage unit 103, the request issuance unit 105 is notified to that effect and the template is acquired from the master server 4 (step S103). That is, a template request is transmitted from the request issuing unit 105 to the master server 4, and a template corresponding to the request is returned from the master server 4. The returned template is received by the information acquisition unit 106 and output to the cache registration unit 107 and the page generation unit 108. Then, the template is stored as a cache in the storage unit 103 by the cache registration unit 107 (step S104). Further, the page generator 108 outputs the template returned from the master server 4 to the M cache search unit 104.

  Through the above processing, the web page template requested from the client terminal 1 is acquired from the storage unit 103 or the master server 4 and input to the M cache search unit 104. The template is a framework of the web page, and includes information on modules to be arranged in the web page and positions where the modules are arranged. Therefore, the module information necessary for generating the web page is acquired from the template by the M cache search unit 104 (step S105), and whether all the modules are cached in the storage unit 103 is searched (step S106). . If all necessary modules are cached in the storage unit 103, these modules are read out and output together with the template to the page generation unit 108.

  On the other hand, if there is a necessary module that is not cached in the storage unit 103, the request issuing unit 105 is notified to that effect, and the necessary module is acquired from the master server 4 (step S 107). That is, a module request for requesting a necessary module is transmitted from the request issuing unit 105 to the master server 4, and a module according to the request is generated and returned by the master server 4 and the application servers 5-1 to 5-4.

  Here, in the present embodiment, since the modules constituting the web page are cached in the storage unit 103 as a unit, for example, even a web page requested for the first time is the same as a web page generated in the past. As for the module to be used, a web page can be generated using the cached module, and the processing load of module generation by the master server 4 can be reduced. Further, since the general-purpose web server 100 that caches templates and modules and the master server 4 that actually generates modules are separated, the general-purpose web server 100 can generate web pages regardless of the type of web page or the site. . For these reasons, if only the number of general-purpose web servers 100 is adapted to the access peak, the minimum number of master servers 4 is sufficient. Since the general-purpose web server 100 can generate web pages of any site, even if access to a web page of a certain site decreases, the surplus general-purpose web server 100 can generate a web page of another site. It is possible to reduce useless costs.

  Returning to the description of FIG. 4 again, the returned necessary module is received by the information acquisition unit 106 and output to the cache registration unit 107 and the page generation unit 108. Then, of the modules acquired as necessary modules, static modules that do not change for a relatively long time are stored as caches in the storage unit 103 by the cache registration unit 107 (step S108). At this time, dynamic modules that change frequently and personalized modules including user-specific information may not always be used when the next web page is requested even if they are cached in the storage unit 103. Discarded by 107.

  Through the above processing, the web page template and the required module requested from the client terminal 1 are acquired from the storage unit 103 or the master server 4 and input to the page generation unit 108. Therefore, the page generation unit 108 incorporates the module into the template and generates a web page (step S109). The generated page data of the web page is transmitted from the page transmission unit 109 to the client terminal 1 that issued the page request (step S110), and the web page is displayed on the client terminal 1.

  As described above, according to the present embodiment, the general-purpose web server caches a web page template and a module for each part constituting the web page, and only when the necessary template or module is not cached, Get templates and modules from the server. For this reason, about the part which is common with the web page produced | generated in the past, a web page can be produced | generated using the module cached by the general-purpose web server, and the processing load of the module production | generation by a master server can be reduced. For the peak of access, only the number of general-purpose web servers needs to be adjusted. Even if the peak of access to a site converges, the surplus general-purpose web server is used to generate web pages for other sites. Therefore, it is possible to reduce wasteful costs while ensuring processing capability that can cope with concentration of access.

(Embodiment 2)
The feature of the second embodiment of the present invention is that the module management server manages module information cached in a plurality of general-purpose web servers, and all the modules that are frequently used for generating web pages are all It is a point to copy to the general-purpose web server.

  FIG. 5 is a diagram showing an overall configuration of the web page generation system according to the present embodiment. In the figure, the same parts as those in FIG. In this web page generation system, module information cached in the general-purpose web server 100 is reported from the general-purpose web server 100 to the module management server 200 one by one. The general web server 100 that has not cached this module is instructed. As a result, when a plurality of general-purpose web servers 100 are installed, all the general-purpose web servers 100 cache modules that are frequently used, further reducing the processing load on the master servers 4-1 and 4-2. can do.

  FIG. 6 is a block diagram showing an internal configuration of the general-purpose web server 100 according to the present embodiment. In this figure, the same parts as those in FIG. The general-purpose web server 100 shown in FIG. 6 includes a request reception unit 101a, a T cache search unit 102, a storage unit 103, an M cache search unit 104, a request issue unit 105a, an information acquisition unit 106, a cache registration unit 107, and a page generation unit 108. , A page transmission unit 109, a cache content report unit 301, a duplication instruction reception unit 302, and a cache duplication unit 303.

  The request reception unit 101a receives a page request (indicated as “page REQ” in FIG. 6) transmitted from the client terminal 1, and notifies the T cache search unit 102 of information on the requested web page. Further, the request reception unit 101a receives a module request (indicated as “module REQ” in FIG. 6) transmitted from another general-purpose web server 100, and notifies the cache duplication unit 303 of information on the requested module.

  When notified from the T cache search unit 102 that the template is not cached, the request issuing unit 105a transmits a template request for requesting this template (indicated as “template REQ” in FIG. 6) to the master server 4. . Further, when the request issuing unit 105a is notified from the M cache searching unit 104 that the module is not cached, the request issuing unit 105a sends a module request for requesting this module (indicated as “module REQ” in FIG. 6) to the master server 4. Send. Further, when the request issuing unit 105 a is notified from the duplication instruction receiving unit 302 that the module cached in the other general-purpose web server 100 is to be duplicated, the request issuing unit 105 a sends a module request for requesting this module to the other general-purpose web server 100. Send.

  When a new module is cached in the storage unit 103 by the cache registration unit 107, the cache content report unit 301 reports the cached module to the module management server 200. Further, when the cached module is searched for by the M cache search unit and used for generating a web page, the cache content report unit 301 reports the used module to the module management server 200.

  The duplication instruction receiving unit 302 receives a duplication instruction for instructing duplication of a module cached in another general-purpose web server 100 from the module management server 200, and notifies the request issuing unit 105a to that effect.

  When a module request from another general-purpose web server 100 is accepted by the request accepting unit 101a, the cache duplicating unit 303 reads out the requested module from the storage unit 103 and duplicates it, and copies the copied module to the other general-purpose requester. It transmits to the web server 100.

  FIG. 7 is a block diagram showing a main configuration of the module management server 200 according to the present embodiment. The module management server 200 illustrated in FIG. 7 includes a cache content reception unit 201, a management table 202, a usage count determination unit 203, a schedule adjustment unit 204, and a duplication instruction transmission unit 205.

  The cache content receiving unit 201 receives the module cache status, the cached module usage status, and the like from each of the general-purpose web servers 100 and updates the management table 202.

  The management table 202 stores which general-purpose web server 100 is cached for each module, and stores the number of times each module is used to generate a web page. Specifically, the management table 202 has a format as shown in FIG. 8, for example. That is, the registration time when each module is registered in the general-purpose web server 100 as a cache, the latest use time used for generating a web page, the remaining valid time stored as a cache, and the number of uses are stored in the identification symbol of each module. It is stored in association.

  In the management table 202 shown in FIG. 8, for example, module 01 is registered as a cache at 13:48:00 on general-purpose web server 100 called server # 1, and a web page is generated at server # 1 at 14:23:40. Is used. If this module 01 is not used in the remaining effective time of 2 minutes 51 seconds in the server # 1, it will be deleted. The remaining effective time is set to a predetermined effective time for each module every time the latest use time is updated, and is counted down. In addition, the number of times that this module 01 is used to generate web pages in all the general-purpose web servers 100 is 1089 times. The modules whose information is managed in the management table 202 are cached in the general-purpose web server 100, and therefore dynamic modules and personalized modules are excluded. Therefore, for example, in FIG. 8, information regarding the modules 04 and 05 is not managed.

  The usage count determination unit 203 compares the usage count for each module stored in the management table 202 with a predetermined threshold, determines that a module having the usage count equal to or greater than the predetermined threshold is to be copied to all the general-purpose web servers 100, The determined module is notified to the schedule adjustment unit 204. In other words, a module that is used frequently is a module that is used in many web pages, and by registering it as a cache in all general-purpose web servers 100, the processing load of module generation by the master server 4 is further reduced. I think it can be done.

  The schedule adjustment unit 204 refers to the registration status of modules determined to be copied to all the general-purpose web servers 100 in the management table 202, and only a large number of copies from a specific general-purpose web server 100 increase, or a plurality of general-purpose web servers. The module duplication schedule is adjusted so that the server 100 does not request duplication to one general-purpose web server 100 at the same time. At this time, the schedule adjustment unit 204 adjusts the schedule so that the duplication is performed within the cached time in consideration of the remaining valid time of the module. In addition, for example, even in the general-purpose web server 100 in which the module is not cached at the present time, the module is cached after duplication. Do not concentrate on the server 100.

  The duplication instruction transmission unit 205 transmits the duplication instruction to the general-purpose web server 100 that is a new destination of the duplicated module according to the duplication schedule adjusted by the schedule adjustment unit 204.

  Next, the operation of the module management server 200 configured as described above will be described with reference to the flowchart shown in FIG.

  When a new module is cached in the general-purpose web server 100 or the cached module is used for generating a web page, the cache contents report unit 301 of the general-purpose web server 100 sends these cache contents to the module management server 200. To be reported. The cache content reported from the general-purpose web server 100 is received by the cache content receiving unit 201 of the module management server 200 (step S201).

  The reported cache contents are reflected and updated in the management table 202 (step S202). Specifically, when a module is newly cached, the time when the corresponding module is registered as a cache in the general-purpose web server 100 and the valid time for caching are registered in the management table 202. When the cached module is used for web page generation, the latest use time of the corresponding module is updated in the management table 202, and the use count is incremented by one.

  Of the items in the management table 202 thus updated, the usage count is monitored by the usage count determination unit 203, and it is determined whether or not the usage count for each module is equal to or greater than a predetermined threshold (step S203). If there is no module whose number of uses is equal to or greater than the predetermined threshold (No in step S203), the cache contents are continuously received from the general-purpose web server 100 and the management table 202 is updated.

  If there is a module whose usage count is equal to or greater than a predetermined threshold (Yes at step S203), the usage count determination unit 203 may cause the general-purpose web server 100 that has not cached this module to cache the copied module. The schedule adjustment unit 204 is notified of the determination. Then, the schedule adjustment unit 204 adjusts the schedule for copying from the general-purpose web server 100 that caches a frequently used module to the general-purpose web server 100 that is not cached (step S204).

  In other words, the schedule adjustment unit 204 adjusts the schedule for equalizing the processing load of each general-purpose web server 100 so that requests for duplicating the module are not concentrated only on the specific general-purpose web server 100 caching the module. . At this time, the schedule adjustment unit 204 refers to the remaining valid time in the management table 202 and adjusts the schedule so that the cached module is copied before being deleted. Further, even in the general-purpose web server 100 in which the module is not cached at the present time, after the copied module is cached, the schedule may be adjusted as the general-purpose web server 100 as the copy source.

  When the schedule for copying the module is adjusted by the schedule adjusting unit 204, a copy instruction is transmitted from the copy instruction transmitting unit 205 to the general-purpose web server 100 that is the copy destination according to this schedule (step S205). Here, the replication instruction is not transmitted to the replication-purpose general-purpose web server 100 in which the module is already cached, but is transmitted to the replication-destination general-purpose web server 100 in which the module is not yet cached. Thus, it is possible to simplify the control in the general-purpose web server 100 that is the replication destination. That is, in the copy destination general-purpose web server 100, it is sufficient that the copy instruction is received by the copy instruction receiving unit 302, a module request is issued from the request issuing unit 105a, and the module is acquired from the master server 4. Therefore, it is only necessary to perform control that only changes the transmission destination of the module request.

  Next, an operation of copying a module from a general-purpose web server 100 in which a frequently used module is cached to another general-purpose web server 100 in which this module is not cached will be described with reference to the sequence diagram shown in FIG. explain.

  First, when a web page is generated in the general-purpose web server 100, a necessary module is acquired from the master server 4, and the acquired module is registered as a cache in the storage unit 103 (step S301). When the module is cached in the storage unit 103, the cache content report unit 301 reports the cache content to the module management server 200 (step S302).

  In the module management server 200, the cache content is received by the cache content receiving unit 201, and the management table 202 is updated according to the content (step S303). Here, the registration time when the module is cached in the general-purpose web server 100 and the valid time of the cached module are stored in the management table 202. The number of times the module is used is determined by the number-of-uses determination unit 203. Here, the number of times the module is used is equal to or greater than a predetermined threshold value, and it is determined that the module is copied to another general-purpose web server 100. And When the module duplication is determined, the schedule adjustment unit 204 adjusts the duplication schedule (step S304), and the duplication instruction is transmitted from the duplication instruction transmission unit 205 to the other general-purpose web server 100 according to the schedule (step S305). ).

  In the other general-purpose web server 100, the duplication instruction is received by the duplication instruction receiving unit 302, and a module request for requesting the module for which duplication is instructed by the request issuing unit 105a is transmitted to the general-purpose web server 100 (step S306). In the general-purpose web server 100, the request reception unit 101a receives a module request and notifies the cache duplication unit 303 of information on the requested module. Then, the cache replication unit 303 reads out the module requested from the other general-purpose web server 100 from the storage unit 103, duplicates it, and transmits it to the other general-purpose web server 100 (step S307). This module is received by the information acquisition unit 106 of another general-purpose web server 100 and registered as a cache in the storage unit 103 by the cache registration unit 107 (step S308).

  By duplicating such a module, a module that is frequently used is cached in all the general-purpose web servers 100, and the usage rate of the modules cached when the web page is generated in the general-purpose web server 100 is improved. 4 can further reduce the processing load of module generation.

  As described above, according to the present embodiment, the module management server receives a report of the cache contents from the general-purpose web server, grasps the modules cached in each general-purpose web server, and for the modules that are frequently used, Replicate from a cached generic web server to an uncached generic web server. For this reason, it is possible to generate a web page by caching a module that is frequently used by all general-purpose web servers, and further reduce the processing load on the master server by further reducing the module generation by the master server.

(Embodiment 3)
A feature of the third embodiment of the present invention is that, when a necessary module is not cached in the general-purpose web server, it is not cached in another general-purpose web server before requesting the master server to generate this module. Check with the server and replicate if it is cached.

  Since the entire configuration of the web page generation system according to the present embodiment is the same as that of the second embodiment (FIG. 5), description thereof is omitted. In the present embodiment, the internal configurations of the general-purpose web server 100 and the module management server 200 are different from those of the second embodiment.

  FIG. 11 is a block diagram illustrating an internal configuration of the general-purpose web server 100 according to the present embodiment. In this figure, the same parts as those in FIGS. 2 and 6 are denoted by the same reference numerals, and the description thereof is omitted. A general-purpose web server 100 illustrated in FIG. 11 includes a request reception unit 101a, a T cache search unit 102, a storage unit 103, an M cache search unit 104, a request issue unit 105b, an information acquisition unit 106, a cache registration unit 107, and a page generation unit 108. , A page transmission unit 109, a cache content report unit 301, a sharing request unit 401, and a cache replication unit 303.

  When the request issuing unit 105b is notified from the T cache search unit 102 that the template is not cached, the request issuing unit 105b transmits a template request for requesting this template (indicated as “template REQ” in FIG. 11) to the master server 4. . When the request issuing unit 105b is notified from the sharing request unit 401 that the module cached in the other general-purpose web server 100 is to be copied, the request issuing unit 105b receives a module request for requesting this module ("module REQ" in FIG. 11). (Notation) is transmitted to the other general-purpose web server 100. Furthermore, when the request issuing unit 105b is notified from the sharing request unit 401 to the master server 4 that the module is requested, the request issuing unit 105b transmits a module request for requesting the module to the master server 4.

  When the share request unit 401 is notified from the M cache search unit 104 that the module is not cached, the share request unit 401 requests sharing of the module with another general-purpose web server 100 that has cached the module. Is transmitted to the module management server 200. If a desired module is cached in another general-purpose web server 100, the sharing request unit 401 sends a copy instruction for instructing duplication of the cached module to the other general-purpose web server 100 from the module management server 200. The request is issued and notified to the request issuing unit 105b. On the other hand, if the desired module is not cached in the other general-purpose web server 100, the sharing request unit 401 receives an error message from the module management server 200 and issues a request to the master server 4 to request the module. Notification to the unit 105b.

  FIG. 12 is a block diagram showing a main configuration of the module management server 200 according to the present embodiment. In this figure, the same parts as those in FIG. The module management server 200 illustrated in FIG. 12 includes a cache content receiving unit 201, a management table 202, a sharing request receiving unit 501, a cache presence / absence determining unit 502, a schedule adjusting unit 204, and a duplication instruction transmitting unit 205a.

  The sharing request receiving unit 501 receives a sharing request indicating that the module is desired to be shared from the general-purpose web server 100 and notifies the cache presence / absence determining unit 502 of the module desired to be shared.

  The cache presence / absence determination unit 502 refers to the management table 202 to determine whether the module notified from the cache presence / absence determination unit 502 is cached in any of the general-purpose web servers 100. Then, when determining that the module is cached in the general-purpose web server 100 other than the general-purpose web server 100 that requested sharing, the cache presence / absence determination unit 502 determines that the module is copied between the general-purpose web servers 100 and determines The schedule adjustment unit 204 is instructed to adjust the schedule for duplicating the created module. Further, when it is determined that the desired module is not cached in any of the general-purpose web servers 100, the cache presence / absence determination unit 502 transmits a copy instruction transmission unit so as to transmit an error message to the general-purpose web server 100 that has requested sharing. Instruct to 205a.

  The duplication instruction transmission unit 205a transmits the duplication instruction to the general-purpose web server 100 that is a new destination of the duplicated module according to the duplication schedule adjusted by the schedule adjustment unit 204. Further, when the desired module is not cached in any general-purpose web server 100, the duplication instruction transmission unit 205a sends an error message to the general-purpose web server 100 that has transmitted the sharing request.

  Next, the operation of the module management server 200 configured as described above will be described with reference to the flowchart shown in FIG. In FIG. 13, the same parts as those in FIG. 9 are denoted by the same reference numerals, and detailed description thereof is omitted.

  When the cache content is transmitted from the general-purpose web server 100, the cache content is received by the cache content receiving unit 201 of the module management server 200 (step S201). The reported cache contents are reflected and updated in the management table 202 (step S202).

  Also, in any general-purpose web server 100, if a module required for generating a web page is searched from the storage unit 103 by the M cache search unit 104 and the required module is not cached, the sharing request unit 401 A sharing request for requesting sharing of a necessary module cached in another general-purpose web server 100 is transmitted to the module management server 200. This sharing request is received by the sharing request receiving unit 501 of the module management server 200 (step S401).

  When the sharing request is received, the cache presence / absence determining unit 502 refers to the management table 202 and determines whether or not the module requested to be shared is cached in any of the general-purpose web servers 100 (step S402). . As a result, if the module is cached in any one of the general-purpose web servers 100 (Yes in step S402), the cache presence determination unit 502 copies the copy-destination general-purpose web server 100 that has transmitted the sharing request and the module cached. The schedule adjustment unit 204 is instructed to adjust the module duplication schedule with the other original general-purpose web server 100. Then, the schedule adjustment unit 204 adjusts the module duplication schedule between the two general-purpose web servers 100 (step S403).

  That is, for example, the processing load of the general-purpose web server 100 is controlled by the schedule adjustment unit 204 so that the processing is not concentrated on a specific general-purpose web server 100 such that the general-purpose web server 100 that is performing duplication of another module is used as a duplication source. The schedule is made even. At this time, the schedule adjustment unit 204 refers to the remaining valid time in the management table 202 and adjusts the schedule so that the cached module is copied before being deleted.

  When the schedule adjustment unit 204 adjusts the module duplication schedule, the duplication instruction is transmitted from the duplication instruction transmission unit 205a to the general-purpose web server 100 that requested sharing (step S205). The transmitted duplication instruction is received by the sharing request unit 401 of the general-purpose web server 100, and a module request is transmitted to the general-purpose web server 100 caching the module by the request issuing unit 105b. Similarly, a module is acquired from the general-purpose web server 100 that caches the module.

  On the other hand, if the module management server 200 determines whether the module requested to be shared is not cached in any general-purpose web server 100 (No in step S402), the cache presence / absence determination unit 502 indicates an error message to that effect. Is transmitted to the general-purpose web server 100 that requested sharing from the replication instruction transmission unit 205a (step S404). The transmitted error message is received by the sharing request unit 401 of the general-purpose web server 100, a module request is transmitted to the master server 4 by the request issuing unit 105b, and thereafter, from the master server 4 as in the first embodiment. Module is acquired.

  Next, an operation in which a cached module is shared between the two general-purpose web servers 100 will be described with reference to a sequence diagram shown in FIG. In FIG. 14, the same parts as those in FIG. 10 are denoted by the same reference numerals, and detailed description thereof is omitted.

  First, when a web page is generated in the general-purpose web server 100, a necessary module is acquired from the master server 4, and the acquired module is registered as a cache in the storage unit 103 (step S301). When the module is cached in the storage unit 103, the cache content report unit 301 reports the cache content to the module management server 200 (step S302).

  In the module management server 200, the cache content is received by the cache content receiving unit 201, and the management table 202 is updated according to the content (step S303). Further, it is assumed that when a web page is generated in another general-purpose web server 100 different from the general-purpose web server 100 in which the module is cached, a cache miss in which a necessary module is not cached has occurred (step S501). At this time, the sharing request unit 401 of the other general-purpose web server 100 transmits a required module sharing request to the module management server 200 (step S502).

  The transmitted sharing request is received by the sharing request receiving unit 501 of the module management server 200, and the cache presence / absence determining unit 502 determines the presence / absence of a general-purpose web server in which a necessary module is cached. Assume that a module registered in 100 is a necessary module in another general-purpose web server 100. For this reason, it is determined by the cache presence / absence determination unit 502 to replicate the module from the general-purpose web server 100 to another general-purpose web server 100, and the schedule adjustment unit 204 adjusts the duplication schedule (step S304). A duplication instruction is transmitted from the duplication instruction transmitting unit 205 to another general-purpose web server 100 (step S305). If the necessary module is not cached in any general-purpose web server 100, an error message to that effect is transmitted from the duplication instruction transmission unit 205 to another general-purpose web server 100.

  In the other general-purpose web server 100, the sharing request unit 401 receives a duplication instruction or an error message, and determines whether or not the module can be shared depending on whether or not the duplication instruction is received (step S503), and the duplication instruction is received. If so (step S503 Yes), a module request for requesting a module whose copy is instructed by the request issuing unit 105b is transmitted to the general-purpose web server 100 (step S306). Similarly to the second embodiment, the module copied by the cache copying unit 303 of the general-purpose web server 100 is returned to the other general-purpose web server 100 (step S307), and is stored in the storage unit 103 of the other general-purpose web server 100. It is registered as a cache (step S308).

  By duplicating such a module, even if a necessary module is not cached in the general-purpose web server 100, the cached modules are shared by all the general-purpose web servers 100, so that the master server 4 can generate modules. The dependency is reduced, and the processing load of module generation by the master server 4 can be further reduced.

  On the other hand, if an error message is received by the sharing request unit 401 (No in step S503), a module request for requesting a necessary module is transmitted to the master server 4 by the request issuing unit 105b (step S504). Then, as in the first embodiment, the module generated by the master server 4 is returned to the other general-purpose web server 100 (step S505), the web page is generated, and the module is registered as a cache (step S505). S308).

  As described above, according to the present embodiment, when a module necessary for generating a web page is not cached in the general-purpose web server, the module management server is requested to share the module, and the module is cached. If there is a general-purpose web server, the module is copied from the cached general-purpose web server to the general-purpose web server requested to be shared. For this reason, all general-purpose web servers can substantially share the contents of the cache, and the module generation by the master server can be further reduced to further reduce the processing load on the master server.

  In each of the above embodiments, when a module request is transmitted from the request issuing unit 105, 105a, 105b of the general-purpose web server 100 to the master server 4, one module is generated and returned to the general-purpose web server 100. However, at this time, depending on the type of module, the master server 4 may generate a plurality of replaceable modules and return them to the general-purpose web server 100 at the same time. In other words, for example, for modules that include links to web pages or advertisements for the purpose of promoting the increase in the number of browsing by the site provider side, several types of replaceable modules may be prepared. The modules may be generated collectively by the master server 4 and cached in the general-purpose web server 100. Thereby, the frequency | count of module request transmission from the general-purpose web server 100 to the master server 4 can be reduced.

  In each of the above-described embodiments, the case where the web page generation process is realized on a computer (that is, on the general-purpose web server 100) has been described. However, a program for realizing the web page generation process can be read by a computer. The web page generation process may be realized by recording the program on a recording medium, causing the computer to read and execute the program recorded on the recording medium.

  FIG. 15 is a block diagram illustrating a hardware configuration of a computer 600 that realizes the web page generation process. As shown in FIG. 15, the computer 600 includes a CPU 601 that executes the program, an input device 602 that inputs data, a ROM 603 that stores various data, a RAM 604 that stores calculation parameters and the like, and a web page generation process. A reading device 605 that reads a program from a recording medium 610 that stores a program for realizing the above, an output device 606 such as a display, and a network interface 607 that exchanges data with other computers via the network 2 Are connected by a bus 608.

  The CPU 601 implements web page generation processing by reading a program recorded on the recording medium 610 via the reading device 605 and then executing the program. Examples of the recording medium 610 include an optical disk, a flexible disk, a CD-ROM, and a hard disk. This program may be installed in the computer 600 via the network 2. Similarly, the module management processing on the module management server 200 in the second embodiment and the third embodiment can also be realized by the hardware configuration described above.

  The present invention can be applied to a case where wasteful costs are reduced while ensuring processing capability that can cope with concentration of access.
