This application is a National Stage application under 35 U.S.C. §371 of International Application No. PCT/JP2010/003720, filed on Jun. 3, 2010, which claims priority to Japanese Application No. 2009-151480, filed on Jun. 25, 2009, the contents of each of the foregoing applications being incorporated by reference herein.

TECHNICAL FIELD

The present invention relates to an information processing apparatus which is connected to a Web server and has a Web browser for displaying an operation screen provided by the Web server, a control method of the information processing apparatus, and a program for causing a computer to perform the control method.

BACKGROUND ART

It is known that an information processing apparatus such as a PC (personal computer) or the like is connected to a Web server located on a network and an operation screen provided by the Web server is displayed on a Web browser of the information processing apparatus.

In such a case, the Web browser of the information processing apparatus requests the operation screen to the Web server, and then a Web application on the Web server returns to the information processing apparatus a response with an HTML (Hyper Text Markup Language) file for causing the Web browser to display the operation screen in response to a request from the information processing apparatus. Then, the Web browser of the information processing apparatus analyzes the received HTML file, and thus displays the operation screen based on descriptions of the HTML file.

Besides, if a user inputs an instruction through the operation screen displayed on the Web browser, the Web browser notifies the Web server of the input instruction. Then, the Web application on the Web server, which received such a notification, performs a process according to the input instruction.

By the way, recently, there are many kinds of MFPs (Multi Function Peripherals) each of which has a scanner and a printer. Among these MPFs, there are some kinds of MFPs each of which is equipped with such a Web browser as described above. Then, the MFP like this displays an operation screen provided by a Web server on the Web browser of the relevant MFP according to such a procedure as described above, and thus accepts various instructions from a user.

CITATION LIST

Patent Literature

Further, a technique as disclosed in Patent Literature 1 has been thought. That is, according to the description in Patent Literature 1, a Web server provides an operation screen for inputting instructions to use respective functions provided in an MFP. Namely, a user of the MFP inputs the instruction to the MFP through the operation screen provided by the Web server and displayed on a Web browser. Then, the Web browser of the MFP notifies the Web server of the input instruction.

Next, the Web server, which received such a notification, requests the MFP to perform various processes according to the contents of the instructions input by the user. Then, the MFP, which accepted such a request, performs the requested process. Thus, it is unnecessary to hold, in the MFP, all menu data for operating the MFP. Further, it is possible to easily change the menu data on the Web server.

Typically, in a case where the Web application on the Web server performs the process on the basis of the instruction input through the operation screen displayed on the Web browser, a new operation screen is displayed on the Web browser according to completion of the process by the Web application. That is, when the process by the Web application is completed, the Web server generates HTML data for the operation screen for notifying a user of the completion of the process or the operation screen for causing a user to perform a next operation. Then, the Web server transmits to the Web browser the generated HTML data as a response to the request transmitted from the Web browser.

On the other hand, there is a case where, in regard to the Web browser installed in the information processing apparatus such as a PC, a MFP or the like, a time limit (time out period) until reception of a response from the Web server after transmission of a request to the Web server has been set. Then, if there is no response from the Web server within the time out period, the Web server performs a time out process. Here, it should be noted that the time out process is a process to invalidate the transmitted request. Namely, if the transmitted request is invalidated, for example, it is possible to stop waiting for the response to the transmitted request. Thus, it is possible to set a state of enabling to transmit a new request. Also, at this time, there is a case where a process to discard a session itself to release resources of the Web browser.

However, as disclosed in above-described Patent Literature 1, in the case where the MFP transmits the request to the Web server based on the operation performed by the user through the operation screen displayed on the Web browser of the MFP and then the Web server requests the MFP to perform the process based on the request transmitted from the MFP, such a problem as described below is conceivable.

That is, in the constitution as disclosed in Patent Literature 1, a result of the process performed by the MFP is once notified to the Web server. Then, the Web server, which received such a notification, transmits to the Web browser the HTML data necessary to notify the processed result, as a response to the request first received from the Web browser. At this time, if it takes a time for the MFP to perform the process based on the request from the Web server, a long time is necessary from Web server's reception of the request from the Web browser to return of the response to the Web browser. Therefore, if the above time out process is performed by the Web browser, the response returned from the Web server is not normally received by the Web browser. Thus, it is impossible to notify the user of the result of the process performed by the MFP.

DISCLOSURE OF INVENTION

The present invention has been completed in consideration of such a problem as described above, and aims to provide a mechanism of not invalidating, in a case where a process requested by a Web server is being performed, a request transmitted by a Web browser.

To achieve this, the present invention is characterized by providing an information processing apparatus, which is connected to a Web server and includes a Web browser for displaying an operation screen provided by the Web server, comprising: a transmission unit configured to transmit a request to the Web server on the basis of a user operation performed through the operation screen displayed on the Web browser; a processing unit configured to, in a case where it is requested by the Web server to perform a process on the basis of the request transmitted by the transmission unit, perform the requested process; and a control unit configured to, in a case where the processing unit is performing the process requested by the Web server, not invalidate the request transmitted by the transmission unit, and to, in a case where the processing unit does not perform the process requested by the Web server, invalidate the request transmitted by the transmission unit according to that there is no response from the Web server and a predetermined time out period elapses after the transmission unit transmits the request.

A network I/F315connects the control unit310(Web server102) with the LAN110. The network I/F315transmits and receives various information between the network I/F315and another apparatus on the LAN110.

FIG. 4is a diagram for describing a software configuration of the whole information processing system. Functions of respective functional sections illustrated inFIG. 4are realized by a process that the CPU211and the CPU311respectively provided in the MFP101and the Web server102perform control programs.

The MFP101has a Web browser430, a session/service management unit440, a service provider450and a LOG recording unit460. Respective functions of the Web browser430, the session/service management unit440, the service provider450and the LOG recording unit460are realized by a process that the CPU211included in the MFP101performs control programs.

The Web browser430has a communication section431, an analysis section432, a session management section433and a screen display section434. The communication section431communicates with a presentation section411of a Web application410in accordance with an HTTP (Hyper Text Transfer Protocol). More specifically, the communication section431transmits information to be input via an operation screen displayed with the Web browser430as a request for the Web application410. In addition, the communication section431receives a response (a processed result) to be transmitted from the Web application410.

The analysis section432analyzes the response received from the Web application410. Management data such as a session ID or the like issued by the Web application410or HTML data is included in the response. The description of indicating the content of an operation screen to be displayed on the Web browser430is included in the HTML data.

The session management section433judges whether or not the session ID acquired by the analysis of the analysis section432is a newly-issued session ID. And, if it is the newly-issued session ID, this session ID is registered in the session/service management unit440to be described later.

The screen display section434displays an operation screen on the operation unit219on the basis of the analysis result of the HTML data analyzed by the analysis section432.

The session/service management unit440manages a session ID used for uniquely identifying a session to be established between the Web browser430and the Web server102. The session ID is issued by the Web server102. In addition, the session/service management unit440manages a performing situation of a process requested from the Web server102to the service provider450on the basis of information transmitted from the Web browser430to the Web server102in each session. Incidentally, it is assumed that the performing situation of the process requested to the service provider450is called a service situation.

The service provider450has a communication section451, a job generation section452and a service management section453. The communication section451accepts a processing request from a logic section412in the Web application410to be described later. Note that a session ID indicating a session between the Web browser430and the Web application410is included in this processing request.

The job generation section452receives the processing request accepted by the communication section451and generates a job for performing the requested process and then performs the job. Furthermore, the job generation section452records a performed result of the job in the LOG recording unit460.

The service management section453updates the service situation to be managed in the session/service management unit440in accordance with the performing situation of the job performed by the job generation section452. More specifically, when it is started to perform the job, a value of the service situation corresponding to the session ID included in the processing request to be managed in the session/service management unit440is set to “in performance”. When the performance of the job ends, a value of the service situation corresponding to the session ID included in the processing request is set to “end”. As described above, a result of having performed the job or an execution LOG of application software functioning on the MFP101is recorded in the LOG recording unit460.

The Web server102has the Web application410and a LOG recording unit420. Respective functions of the Web application410and the LOG recording unit420are realized by a process that the CPU311included in the Web server102performs control programs.

The Web application410receives information to be transmitted from the Web browser430as a request and then performs a process on the basis of the received information. A processed result is transmitted from the Web application410to the Web browser430as a response.

The Web application410has the presentation section411and the logic section412. The presentation section411communicates with the communication section431and receives a request transmitted from the MFP101. Next, the presentation section411notifies the received request to the logic section412and waits for a response to be sent from the logic section412. The presentation section411, which received the response sent from the logic section412, transmits HTML data corresponding to an operation screen to be displayed with the Web browser430of the MFP101as a response in accordance with the response content. Information which was input via the operation screen displayed on the Web browser430of the MFP101is transmitted from the communication section431as a request.

The logic section412performs various processes in accordance with the request notified from the presentation section411and requests to perform a process to the MFP101. More specifically, the logic section412requests to perform a printing process to be performed by the printer220of the MFP101, a reading process to be performed by the scanner221of the MFP101or a transmission process to be performed via the network I/F218.

In case of requesting to perform the process to the MFP101, the logic section412communicates with the communication section451in the service provider450included in the MFP101. Then, the logic section412receives a result of the process performed by the MFP101from the MFP101and records the result in the LOG recording unit420. The Web application410records results of various processes to be performed at the Web server102in the LOG recording unit420.

FIG. 5is a diagram for describing the session/service management unit440. The session/service management unit440has a data base of which the constituent sections are a column “session ID”501and a column “service situation”502. The session/service management unit440manages a session between the Web browser430and the Web application410and a performing situation of a process to be performed at the MFP101by associating the session with the performing situation by the column “session ID”501and the column “service situation”502. That is, plural sessions and the performing situations of processes corresponding to respective sessions are managed in the session/service management unit440by associating the plural sessions with the performing situations.

A session ID for identifying the session between the Web browser430and the Web application410is stored in the column “session ID”501. The session ID is issued by the Web application410when the Web browser430starts to communicate with the Web application410. The session management section433of the Web browser430registers a newly-issued session ID included in a response sent from the Web application410in the column “session ID”501.

The column “service situation”502indicates the performing situation of a process, which is requested from the logic section412of the Web application410, performed by the service provider450. When it is started to perform the process to be requested from the logic section412, the service management section453to be described later registers a value in the column “service situation”502as “in performance”.

At this time, the service management section453registers the value in the column “service situation”502corresponding to the column “session ID”501in which the session ID included in the request sent from the logic section412is registered. When the process ends, the service management section453to be described later updates the value of the column “service situation”502to “end”.

FIG. 6is a sequence diagram for describing an operation that the Web server102requests to perform the process to the service provider450on the basis of the request sent from the Web browser430and the service provider450performs the process.

Initially, a request600is transmitted from the Web browser430of the MFP101to the Web application410of the Web server102. The Web application410, which received the request600from the Web browser430, issues a session ID in order to uniquely identify a subsequent series of data transmission/reception operations performed with the Web browser430. Note that this session ID is commonly used in communications (the request600, a response601, a request602, a response603, a request604and a response607) between the Web browser430and the Web server102to be described later.

Next, the Web application410transmits the processed result for the request together with the HTML data as the response601to the Web browser430. At this time, the session I/D issued by the Web application410is included in the response601transmitted to the Web browser430.

The Web browser430acquires the session I/D included in the received response601and registers the acquired session I/D in the column “session ID”501of the session/service management unit440. Furthermore, the Web browser430analyzes the HTML data included in the received response601in the analysis section432, and the analyzed result is displayed by the screen display section434.

Next, the Web browser430transmits the next request602to the Web application410in accordance with a user operation performed on an operation screen to be displayed in the screen display section434. The Web application410performs a process for the received request602and transmits the processed result to the Web browser430together with the HTML data as the response603. The Web browser430and the Web application410repeat the foregoing communications performed by the requests and responses.

Here,FIG. 6is a diagram for describing a case that a parameter value, which is necessary to instruct to perform a process of “transmit a file upon scanning an original” and necessary to perform the process, is included in the request604to be transmitted from the Web browser430to the Web application410. Note that a process to be performed by the service provider450in the MFP101is not limited to the process of “transmit a file upon scanning an original” but may be another process such as a printing process or the like.

The Web browser430transmits the next request604to the Web application410by a user operation performed on the operation screen to be displayed in the screen display section434. Note that information such as the parameter value necessary to instruct to perform the process and necessary to perform the process is input by a user according to a user operation performed via the operation screen. However, it is allowed that the parameter value necessary to perform the process is not always input by the user. For example, the parameter value, which is previously held in the Web application410itself as a default set value, may be used.

The Web application410which received the request604acquires a parameter value, which is necessary to instruct to perform the process and necessary to perform the process, included in the request604. Next, the Web application410transmits a request605to the service provider450of the MFP101on the basis of the acquired parameter value which is necessary to instruct to perform the process and necessary to perform the process. At this time, a session I/D (I/D for identifying the session used in communication between the Web browser430and the Web application410) issued by the Web application410is included in the request605. According to this request605, the Web application410requests to perform the process of “transmit a file upon scanning an original” for the service provider450.

The service provider450which received the request605starts to perform the process of “transmit a file upon scanning an original” in accordance with the requested content. At this time, the service provider450acquires the session I/D included in the request605. Then, a value of the column “service situation”502corresponding to the column “session ID”501, in which the acquired session I/D is stored, is updated to “in performance” by referring to the column “session ID”501of the session/service management unit440.

Meanwhile, the Web browser430calculates an elapsed time from after the request604is transmitted until a response sent from the Web application410is returned by using a timer. And, when a time out period has elapsed while the response is not returned yet, the service situation corresponding to the session I/D registered in the service/session management unit440is confirmed. As a result of confirmation, if the service situation is in “in performance”, the Web browser430resets the calculated time without performing a time out process. At this time, it is acceptable that the time out process is not only performed without resetting the calculated time. Alternatively, such the constitution that the time calculation by the timer is not performed during the service situation is in “in performance” and the time calculation is started in accordance with a condition that the service situation became “end” is also acceptable.

The service/session management unit440, which received an inquiry about the service situation from the Web server430, responds a value stored in the column “service situation”502corresponding to the column “session ID”501in which the inquired session ID is registered.

The service provider450updates a value of the column “service situation”502corresponding to the column “session ID”501, in which the session ID acquired from the request605is registered, to “end” when a process requested in the request605ends. Then, the service provider450includes the processed result in a response606, which is sent back to the Web server102.

The Web application410, which received the response606, includes the processed result included in the response606in the response607as a result for the process required in the request604, and the response607is sent back to the Web browser430.

The Web browser430, which received the response607, analyzes HTML data included in the response607and displays an analyzed result screen in the screen display section434.

FIG. 7is a flowchart for describing a series of processes that the Web browser430of the MFP101registers the session ID issued by the Web application410in the session/service management unit440. Respective operations (steps) indicated in the flow chart inFIG. 7are realized by a process that the CPU211of the MFP101performs control programs stored in the HDD214.

In S701, the communication section431of the Web browser430generates a request which includes values or the like input by a user via an operation screen displayed by the screen display section434and transmits the request to the Web application410.

In S702, the communication section431of the Web browser430receives a response transmitted from the presentation section411of the Web application410. The analysis section432of the Web browser430analyzes the received response and the screen display section434of the Web browser430displays the analyzed result on a screen.

In S703, the session management section433of the Web browser430confirms whether or not a session ID acquired by the analysis performed by the analysis section432is changed from the session ID received at the last time. When the session ID is changed from the session ID received at the last time, the session management section433judges that the session ID is newly issued, and the flow advances to S704. When the session ID is same as the session ID received at the last time, the session management section433judges that the session ID is not newly issued, and the flow advances to S705.

In the S704, the session ID, for which the session management section433of the Web browser430judged that it is newly issued in the S703, is registered in the column “session ID”501of the session/service management unit440. At this time, a value of the column “service situation”502corresponding to the column “session ID”501, in which the session ID was registered, is set as “- -”.

In the S705, it is judged whether or not the Web browser430ends the process. When it is judged that the Web browser430does not end the process, the flow returns to the S701. On the other hand, when it is judged that the Web browser430ends the process, the process ends.

FIG. 8is a flowchart for describing a series of processes that the service provider450performs a process requested from the Web server102. Respective operations (steps) indicated in the flow chart inFIG. 8are realized by a process that the CPU211of the MFP101performs control programs stored in the HDD214.

In S801, the communication section451of the service provider450receives a request (a processing request) from the logic section412of the Web application410. The communication section451, which received the request, transmits the request to the service management section453and the job generation section452. The service management section453, which received the request, acquires a session ID included in the request.

In S802, the job generation section452, which received the request, confirms that the MFP101is in a state capable of performing the process requested by the request.

In subsequent S803, the job generation section452generates a job for performing the process requested by the request and starts to perform the job. Namely, the service is called. At this time, the job generation section452notifies a fact of starting to perform the job to the service management section453.

In S804, the service management section453, which received a notification that it was started to perform the job, updates the column “service situation”502corresponding to the column “session ID”501, in which the acquired session ID is registered, to “in performance”.

In S805, it is judged whether or not the process to be performed by the service provider450ends, and when judged that the process ends, the flow advances to S806. That is, the service is performed in S805.

In the S806, the service management section453updates the value of the column “service situation”502of the session/service management unit440updated in the S804to “end” after ending the job. That is, it is judged in S806whether or not the service ends.

Then, in S807, the communication section451includes the performed result of job in the response for the request received in the S801and sends this response back to the logic section412of the Web application410.

FIG. 9is a flow chart for describing a series of processes of confirming a performing situation of the process requested from the Web server102in a case that the response is not returned even though a predetermined time out period has elapsed after the Web browser430transmits the request to the Web server102. Respective operations (steps) indicated in the flow chart inFIG. 9are realized by a process that the CPU211of the MFP101performs control programs stored in the HDD214.

In S901, the session management section433of the Web browser430judges whether or not the predetermined time out period has elapsed without the response for the transmitted request. When the time out period has elapsed, the flow advances to S902. When the time out period does not elapse, the process ends.

In S902, the session management section433confirms a value of the column “service situation”502corresponding to the column “session ID”501in which the session ID of the time out generated session is registered.

In S903, if the value of the column “service situation”502confirmed by the session management section433in the S902is “in performance”, the flow advances to S904. If the value of the column “service situation”502confirmed in the S902is “- -” or “end”, the flow advances to S905.

In the S904, the session management section433resets a time, when it is started to calculate a time period after transmitting the request to the Web server102. Herewith, even when the time out period has elapsed without the response, the Web browser430keeps not to perform a time out process of the Web browser430if the process at the MFP101side requested from the Web server102is in a performing state.

Meanwhile, in the S905, the session management section433performs the time out process. More specifically, by discarding the session established between the Web browser430and the Web server102, thereafter, even if the Web browser430receives the response which has the same session ID as that of the discarded session, the Web browser430disregards (discards) the response as an ineffective response. The screen display section434displays a message which indicates a fact that a time out error was generated. As just described, the time out process is such a process of invalidating the transmitted request. Incidentally, as a process of invalidating the transmitted request, it is allowed that not only the session itself is discarded but also it is stopped to wait for the response for the transmitted request and a state capable of transmitting a new request is only set.

As described above, in the present embodiment, after the Web browser transmits a request to the Web server, when the predetermined time out period has elapsed while the response from the Web server is not returned yet, it is judged whether or not a process based on the request from the Web server is in a performing state. And, if the process based on the request from the Web server is not in a performing state, the transmitted request is invalidated, and if the process based on the request from the Web server is in a performing state, the transmitted request is kept not to be invalidated. Accordingly, even if it is constituted that the Web server provides an operation screen of the MFP, the processed result can be more surely notified to a user.

Second Embodiment

Subsequently, the second embodiment of the present invention will be described. In the second embodiment, in addition to the constitution described in the first embodiment, the constitution that the Web browser430is made to perform a time out process when the service provider450can not return the response (processed result) to the Web server is further added. Note that the same constitutions as those in the above-described first embodiment will be denoted by the same reference numerals and the detailed description thereof will be omitted.

FIG. 10is a flow chart for describing a series of processes that the service provider450performs a process requested from the Web server102. Respective operations (steps) indicated in the flow chart inFIG. 10are realized by a process that the CPU211of the MFP101performs control programs stored in the HDD214.

In the flow chart indicated inFIG. 10, processes of S1001and S1002are added to the processes in the flow chart indicated inFIG. 8.

In the S1001, the communication section451of the service provider450confirms whether or not the transmission of response to the logic section412of the Web application410was resulted in success. When the transmission of response is resulted in success, the process ends, and when the transmission of response is resulted in failure, the flow advances to the S1002. In the S1002, the time out process is instructed to the session management section433of the Web browser430.

FIG. 11is a flow chart for describing a series of processes of confirming a performing situation of a process requested from the Web server102in a case that the response is not returned even though a predetermined time out period has elapsed after the Web browser430transmits a request to the Web server102. Respective operations (steps) indicated in the flow chart inFIG. 11are realized by a process that the CPU211of the MFP101performs control programs stored in the HDD214.

In the flow chart indicated inFIG. 11, a process of S1101is added to the processes in the flow chart indicated inFIG. 9.

In the S1101, the session management section433of the Web browser430judges whether or not a time out instruction is received from the service provider450. When it is judged that the time out instruction was received, the flow advances to the S905, and when it is judged that the time out instruction is not received, the flow advances to the S901.

In the S905, the session management section433performs the time out process. More specifically, by discarding the session established between the Web browser430and the Web server102, thereafter, even if the Web browser430receives the response which has the same session ID as that of the discarded session, the Web browser430disregards (discards) the response as an ineffective response. The screen display section434displays a message which indicates a fact that a time out error was generated. As just described, the time out process is such a process of invalidating the transmitted request. Incidentally, as a process of invalidating the transmitted request, it is allowed that not only the session itself is discarded but also it is stopped to wait for the response for the transmitted request and a state capable of transmitting a new request is only set.

As described above, in the present embodiment, for example, when a network trouble occurs after receiving a processing request from Web server and the service provider became unable to return the response to the Web server, the session between the Web browser and the Web server is discarded. According to this fact, in addition to an effect described in the first embodiment, it can be prevented that the session between the Web browser and the Web server is unnecessarily and continuously held.
