     This application is a continuation of PCT Application No. PCT/CN2016/079813, filed on Apr. 21, 2016, which claims priority to Chinese Patent Application No. 201510224908.5, filed on May 5, 2015, and each application is incorporated by reference in its entirety. 
    
    
     TECHNICAL FIELD 
     The present application relates to the field of computer technologies, and in particular, to recording and restoring a click position in a webpage. 
     BACKGROUND 
     As Internet technologies develop and Internet resources become increasingly abundant, a user can acquire a larger amount of information from the Internet. Providers of Internet services also conduct and analyze user behaviors and network operations related to user access of Internet content (for example, webpages). For example, a user&#39;s preference for a webpage typographic style can be obtained by recording the user&#39;s click behaviors for webpages having the same content but different typographic designs. Also, a user&#39;s interest level for information content can be obtained by recording the user&#39;s click behaviors for different types of information in the webpages. Therefore, obtaining reliable data for user click behavior in webpages can be important for analyzing user behaviors and optimizing a designed system user experience. 
     SUMMARY 
     The present disclosure describes recording and restoring a click position in a webpage. 
     In an implementation, a webpage is divided into a plurality of operating regions, where each of the plurality of operating regions has a reference coordinate position. A reference operating region corresponding to a click operation. A relative coordinate of a click position is calculated with respect to a reference coordinate position of the reference operating region. The relative coordinate of the click position is recorded.

     DETAILED DESCRIPTION 
     The following detailed description describes recording and restoring a click position in a webpage, and is presented to enable any person skilled in the art to make and use the disclosed subject matter in the context of one or more particular implementations. Various modifications, alterations, and permutations of the disclosed implementations can be made and will be readily apparent to those or ordinary skill in the art, and the general principles defined can be applied to other implementations and applications, without departing from the scope of the present disclosure. In some instances, details unnecessary to obtain an understanding of the described subject matter can be omitted so as to not obscure one or more described implementations with unnecessary detail and inasmuch as such details are within the skill of one of ordinary skill in the art. The present disclosure is not intended to be limited to the described or illustrated implementations, but to be accorded the widest scope consistent with the described principles and features. 
     In some implementations, a user&#39;s click behaviors may be analyzed. For example, a webpage can be designed with different design schemes based on different structures, layouts, and styles. Webpages with these different design schemes can be distributed to one or more target users. The click behaviors of the target users can be analyzed to determine the popularity and effectiveness the respective design schemes. The analysis can be used to optimize the webpage. 
     To analyze the user&#39;s click behaviors, the click position, representing the position of the cursor on a webpage where a click operation is performed, can be recorded when the click operation is detected. The position of the click operation can be restored at a later moment when the analysis of the user&#39;s behavior is conducted. 
     In some cases, static methods can be used to record a user&#39;s click behaviors in a webpage depending on the layout of the webpage.  FIG. 1  is a schematic diagram  100  illustrating an example of a webpage layout, according to an implementation of the present disclosure. As illustrated, a webpage  110  is displayed on a display screen  120  of a computing device. The webpage  110  has a left alignment layout. In this example, coordinate  102 , positioned at the upper left corner of the webpage  110 , and having an [x, y] coordinate of [0, 0], is used as a reference coordinate to record click behaviors. 
       FIG. 2  is a schematic diagram  200  illustrating another example of a webpage layout, according to an implementation of the present disclosure. As illustrated, a webpage  210  is displayed on a display screen  220  of a computing device. The webpage  210  has a centered layout. In this example, coordinate  202 , positioned at the top of a vertical central axis  230  of the webpage  210 , and having an [x, y] coordinate of [center, 0], is used as a reference coordinate to record click behaviors. 
     However, these methods do not take into account the operations of a dynamic webpage. The webpage may be different between the time the click positions are recorded and the time of analysis. For example, some regions in the webpage may move, change size, or disappear due to user interactions. 
     In some implementations, a relative coordinate of a click position can be recorded. The relative coordinate of the click position can be calculated based on a reference coordinate position of a reference operating region within the webpage. The relative coordinate can be used to restore the webpage for analysis at a later time.  FIGS. 3-15  and associated descriptions provide additional details of these implementations. 
       FIG. 3  is a flowchart illustrating an example of a method  300  for recording a click position, according to an implementation of the present disclosure. For clarity of presentation, the description that follows generally describes method  300  in the context of the other figures in this description. However, it will be understood that method  300  can be performed, for example, by any system, environment, software, and hardware, or a combination of systems, environments, software, and hardware, as appropriate. In some implementations, various steps of method  300  can be run in parallel, in combination, in loops, or in any order. 
     At  302 , a webpage is divided into a plurality of operating regions. In some cases, the webpage can be divided based on the frame structure of the webpage, historical user behaviors of the webpage, or a combination thereof.  FIG. 4A  illustrates an example of a webpage  410  including a plurality of operating regions, according to an implementation of the present disclosure. As illustrated, the webpage includes a header region  402 , a footer region  404 , a sidebar region  406 , a banner region  412 , an info region  414 , an ad region  416 , and a container region  408 . In one example, these regions are divided based on the frame structure of the webpage. The frame structure of the webpage may include components such as a header, a footer, and a sidebar, and, therefore, each component can be considered a separate operating region. 
     Alternatively or additionally, the operating regions can be divided based on historical user behaviors. In one example, if one operating region, for example the info region  414 , has received user clicks that exceed a threshold number, the info region  414  can be further divided into multiple operating regions. In another example, if user behaviors indicate that clicks of two or more operating regions, for example the info region  414  and the adjacent ad region  416 , are highly coordinated, these two regions can be combined into one operating region. In yet another example, if more than one region of the webpage, for example the header region  402  and the footer region  404 , do not exceed a threshold number, these regions can be combined in one operating region. The historical user behaviors, including, for example, the number of user clicks and the correlation between user clicks, can be stored on the computing device that displays the webpage, on a server, or a combination thereof. The historical number of user clicks can be retrieved before the division of the operating regions. 
     In some cases, prior to dividing a webpage into operating regions, a reference region in the webpage is determined. The reference region may include regions that are likely to receive user clicks. In some cases, the reference region can be divided based on the frame structure of the webpage, historical user behaviors of the webpage, or a combination thereof. For example, a reference region for the webpage  410  may include the banner region  412 , the info region  414 , the ad region  416 , and the sidebar region  406 . On the other hand, margins and spaces on the webpage, may not receive many user clicks that would significantly impact the statistical analysis of user behaviors. These areas may not be included in the reference region. After determining the reference region, the reference region can be further divided into multiple operating regions. In some implementations, the operating regions can be divided directly from the webpage, without first determining an operating region. 
     In some cases, those regions that are not included in the reference region can be grouped into a container region. For example, as shown in  FIG. 4A , the container region  408  can include margins and spaces in the webpage  410  that do not belong to any operating regions. The container region  408  can also include blank regions (for example,  417 ) between block elements, between inline elements, and between a block element and an inline element. Grouping these regions into one container region and sharing a reference coordinate position of the reference region can increase determinability of click coordinates for these regions. 
     In some cases, different operating regions can be adjacent to each other, as shown in  FIG. 4A , or overlap with each other, as shown in  FIG. 4B .  FIG. 4B  illustrates another example of a webpage  420  including a plurality of operating regions, according to an implementation of the present disclosure. As shown in  FIG. 4B , the ad region  416  is nested into the info region  414 . A range or boundary of each operating region may be determined according to the frame structure and the style of the webpage. 
     Returning to  FIG. 3 , from  302 , method  300  proceeds to  304 . 
     At  304 , a reference operating region corresponding to a user click operation is determined. After a user performs a click operation in the webpage, the browser can obtain a Document Object Model (DOM) element (nestable) corresponding to the click operation of the user. Because the operating regions in the webpage are marked on the DOM element, a mark of an operating region can be searched for by layer-by-layer upward recursion. Once the mark of the operating region is found, the click position can be determined to be located in the corresponding operating region. Alternatively or additionally, after finding the mark of the operating region, the browser can also send information of the mark to a server, and the server can determine the operating region corresponding to the click operation of the user. 
       FIG. 5  illustrates an example of a DOM structure  500 , according to an implementation of the present disclosure. The illustrated DOM structure  500  has a nested structure. If a user clicks the text of “Slide 1,” the browser or the server can traverse the nest structure and find an operating region that includes the node [li coor=“slide-1”] as the operating region where the user click is located. 
     Returning to  FIG. 3 , from  304 , method  300  proceeds to  306 , where the relative coordinate of the click position with respect to the reference coordinate position of the reference operating region is calculated. Each operating region has a reference coordinate. The reference coordinate can be determined based on the layout of the operating region. For example, the reference coordinate can be the upper left corner of the operating region if the operating region is left aligned. The reference coordinate can also be the top center of the operating region if the operating region is center aligned. 
       FIG. 6  illustrates an example of a click position determination  600 , according to an implementation of the present disclosure. As illustrated, a click operation is determined to correspond to a banner region  610 . The upper left corner of the banner region  610  is taken as a reference coordinate position  612 , with an [x, y] coordinate of [0, 0]. The relative coordinate of the click position  614  is determined as an [x, y] value. The reference coordinate can be calculated by the browser, the server, or a combination thereof. In some cases, the relative coordinate can have a unit based on the number of pixels between the click position and the reference position. Returning to  FIG. 3 , from  306 , method  300  proceeds to  308 . 
     At  308 , the click position is recorded. The recorded click position can include an indicator indicating the reference operating region and the relative coordinate of the click position with respect to the reference coordinate position. For example, the click position in  FIG. 6  can be recorded as “banner: [x, y].” 
     In some cases, the relative coordinate of the click position can be stored in a server, for example, a web server such as an NGINX server. The NGINX server can also store an operating time of the click operation with the relative coordinates. The NGINX server uses less memory and has strong concurrent capability, and thus is suitable to store many user click positions. Other types of servers can also be used to store click position data. Alternatively or additionally, the browser on the computing device that displays the webpage can determine the operating time of the click operation, store the relative coordinate and the operating time, or a combination thereof. After  308 , method  300  stops. 
     In some cases, method  300  can be implemented on a client terminal that displays the webpage and receives the user clicks. Alternatively or additionally, method  300  can be implemented on a server. In some implementations, the steps of method  300  can be implementated in more than one device. For example, steps  302  and  304  can be implemented on the client terminal that displays the webpage and receives the user click and steps  306  and  308  can be implemented on a server. 
       FIG. 7  is a flowchart illustrating an example of a method  700  for restoring a click position, according to an implementation of the present disclosure. For clarity of presentation, the description that follows generally describes method  700  in the context of the other figures in this description. However, it will be understood that method  700  can be performed, for example, by any system, environment, software, and hardware, or a combination of systems, environments, software, and hardware, as appropriate. In some implementations, various steps of method  700  can be run in parallel, in combination, in loops, or in any order. 
     At  702 , a relative coordinate of a click position with respect to a reference coordinate of a reference operating region is queried. As discussed previously, the relative coordinate is recorded after the click operation is detected. The relative coordinate can be stored on the computing device where the webpage is displayed, or on a web server. Accordingly, the query is sent to the computing device, or the web server. From  702 , the method  700  proceeds to  704 . 
     At  704 , a query response is received. The query response includes the relative coordinate of the click position and an indicator indicating the reference operating region corresponding to the click operation. From  704 , the method  700  proceeds to  706 . 
     At  706 , a current position of the reference operating region in the webpage at a second moment is determined. The second moment can be a time of interest for analyzing the user behavior. In some cases, the operating time when the click operation took place can be referred to as the first moment, and the second moment can be a time between the first moment to the current time when the restoration takes place. 
     In some cases, the position of the operating region in a webpage at the second moment can be determined based on the reference coordinate of the operating region at the first moment.  FIG. 8  illustrates an example of positions of operating regions, according to an implementation of the present disclosure.  FIG. 8  includes a schematic diagram  810  of a webpage at the first moment and a schematic diagram  820  of the webpage at the second moment. At the first moment, the banner region  812  is at the top, and the upper left corner of the banner region  812  is located at a position  814 . The position  814  is taken as the reference coordinate of the banner region  812 , with a coordinate of [0, 0]. At the second moment, the banner region  812  has moved to the lower right portion of the webpage. The upper left corner of the banner region  812  has moved to a position  824 , with a coordinate of [a, b] with respect to the reference coordinate [0, 0]. Accordingly, the position of the banner region  812  at the second moment can be determined to be [a, b]. Returning to  FIG. 7 , from  706 , the method  700  proceeds to  708 . 
     At  708 , the click position of the click operation in the webpage is restored at the second moment. The click position can be restored according to the relative coordinate with respect to the reference coordinate position of the operating region, and the position of the operating region at the second moment. Referring back to  FIG. 8 , because the relative coordinate is [x, y] and the position of the banner region  812  at the second moment is [a, b], the restored position is [x+a, y+b]. The restored click position is used for data analysis at the second moment. This approach enables the analysis of user behaviors by taking account of the movement of the banner region. After  708 , method  700  stops. 
     In some implementations, restoration can further take into account the size change of the operating regions.  FIG. 9  is a flowchart illustrating an example of a method  900  for restoring a click position based on the size of an operating region, according to an implementation of the present disclosure. For clarity of presentation, the description that follows generally describes method  900  in the context of the other figures in this description. However, it will be understood that method  900  can be performed, for example, by any system, environment, software, and hardware, or a combination of systems, environments, software, and hardware, as appropriate. In some implementations, various steps of method  900  can be run in parallel, in combination, in loops, or in any order. 
     At  902 , whether the area of the operating region at the first moment is greater than the area of the operating region at the second moment is determined. In some implementations, the area sizes at different moments are calculated in real-time. If the area of the operating region at the first moment is greater than the area of the operating region at the second moment, the method  900  proceeds from  902  to  904 . 
     At  904 , whether the click position is outside of the operating region at the second moment is determined. If the click position is outside of the operating region at the second moment, method  900  proceeds from  904  to  906 , where the click position is hidden instead of being restored. If the click position of the area of the operating region at the first moment is less than or equal to the area of the operating region at the second moment, method  900  proceeds from  902  to  908 . If the click position is not outside of the operating region at the second moment, method  900  proceeds from  904  to  908 . At  908 , the click position is restored. 
       FIG. 10  illustrates an example of a change of the size of an operating region, according to an implementation of the present disclosure.  FIG. 10  includes a schematic diagram  1010  of a webpage at the first moment and a schematic diagram  1020  of the webpage at the second moment. The size of the banner region  1012  is smaller at the second moment than the size of the banner region  1012  at the first moment. This may be due to a resize operation that takes place between the first moment and the second moment. The click position  1014  was inside the banner region  1012  at the first moment. However, the restored click position  1024  is located outside of the banner region  1012 , because the size of the banner region  1012  has changed. In this case, the restored click position may be hidden from the restored webpage because the restored click position no longer reflects the user behavior correctly. The restored position can thus be removed from the analysis of the user behavior. 
     In some implementations, restoration can further take into account the disappearance of the operating regions.  FIG. 11  is a flowchart illustrating an example of a method  1100  for restoring a click position based on the disappearance of an operating region, according to an implementation of the present disclosure. For clarity of presentation, the description that follows generally describes method  1100  in the context of the other figures in this description. However, it will be understood that method  1100  can be performed, for example, by any system, environment, software, and hardware, or a combination of systems, environments, software, and hardware, as appropriate. In some implementations, various steps of method  1100  can be run in parallel, in combination, in loops, or in any order. 
     At  1102 , whether the operating region exists at the second moment is determined. If the area of the operating region at the second moment does not exist, the method  1100  proceeds from  1102  to  1104 . If the operating region exists at the second moment, method  1100  proceeds from  1102  to  1106 . 
     At  1104 , the click position is hidden instead of being restored. After  1104 , method  1100  stops. 
     At  1106 , the click position is restored. After  1106 , method  1100  stops. 
       FIG. 12  illustrates an example of a disappearance of an operating region, according to an implementation of the present disclosure.  FIG. 12  includes a schematic diagram  1210  of a webpage at the first moment and a schematic diagram  1220  of the webpage at the second moment. The banner region  1212  does not exist at the second moment. This may be due to a close operation of the banner region  1212  that takes place between the first moment and the second moment. The click position  1214  would have been restored at the restored position  1224 , which would be inside the container region  1222 . Therefore, the restored position  1224  can be hidden from the restoration of the webpage, and removed from the analysis because the restored position  1224  no longer correctly reflects the user behavior. 
       FIG. 13  is a schematic diagram illustrating an example of a computing device  1300  that records a click position as described in the present disclosure, according to an implementation of the present disclosure. The device  1300  includes a region determination module  1302 , a division module  1304 , a determination module  1306 , and a processing module  1308 . 
     The region determination module  1302  is configured to determine a reference region in a webpage in which a click position is to be recorded. The division module  1304  is configured to divide the reference region into several operating regions according to a frame structure and a style of the webpage. The division module  1304  is also configured to determine a region other than the reference region in the webpage as an operating region. The division module  1304  is also configured to determine at least one reference coordinate position for each operating region. The determination module  1306  is configured to determine a reference operating region where a click operation of a user is located. The processing module  1308  is configured to, by taking a reference coordinate position of the reference operating region where the click operation is located as a reference, calculate a relative coordinate of the position of the click operation with respect to the reference coordinate position, and record the relative coordinate as a click position of the click operation in the webpage. 
     In some implementations, the processing module  1308  is also configured to record the click position of the click operation in the webpage in a NGINX server; and the processing module  1308  is further configured to record an operating time of the click operation by using the NGINX server. 
     The computing device  1300  can be implementated on a server or on a client terminal that displays the webpage. In some implementations, the modules of the computing device  1300  can be implementated in more than one device. For example, the region determination module  1302 , the division module  1304 , and the determination module  1306  can be implemented on the client terminal that displays the webpage and receives the user click, and the processing module  1308  can be implemented on a server. 
       FIG. 14  is a schematic diagram illustrating an example of a computing device  1400  that restores a click position as described in the present disclosure, according to an implementation of the present disclosure. The device  1400  includes a query module  1402 , a positioning module  1404 , a calculation module  1406 , a comparison module  1408 , and a recognition module  1410 . 
     The query module  1402  is configured to query the relative coordinate of a position of a click operation of a user with respect to a reference coordinate position of an operating region where the click operation is located. The relative coordinate is obtained at a first moment when the click position is recorded. 
     The positioning module  1404  is configured to determine a position of the operating region in the webpage at a second moment. The second moment represents the moment to be analyzed for user behavior analysis and the second moment occurs after the first moment. 
     The calculation module  1406  is configured to restore, at the second moment, a click position of the click operation in the webpage according to the relative coordinate of the position of the click operation with respect to the reference coordinate position of the operating region at the first moment and the position of the operating region in the webpage at the second moment. 
     The comparison module  1408  is configured to determine whether an area of the operating region at the first moment is greater than the area of the operating region at the second moment. The comparison module  1408  is further configured to determine whether the click operation is outside the operating region at the second moment. If the area of the operating region at the first moment is greater than the area of the operating region at the second moment and the click operation is outside the operating region at the second moment, the comparison module  1408  is configured to hide data of the click position in the webpage. 
     The recognition module  1410  is configured to determine whether the operating region exists at the second moment. If the operating region does not exist at the second moment, the recognition module  1410  is configured to hide data of the click position in the webpage.

     Implementations of the subject matter and the functional operations described in this specification can be implemented in digital electronic circuitry, in tangibly embodied computer software or firmware, in computer hardware, including the structures disclosed in this specification and their structural equivalents, or in combinations of one or more of them. Software implementations of the described subject matter can be implemented as one or more computer programs, that is, one or more modules of computer program instructions encoded on a tangible, non-transitory, computer-readable computer-storage medium for execution by, or to control the operation of, data processing apparatus. Alternatively, or additionally, the program instructions can be encoded in/on an artificially generated propagated signal, for example, a machine-generated electrical, optical, or electromagnetic signal that is generated to encode information for transmission to a receiver apparatus for execution by a data processing apparatus. The computer-storage medium can be a machine-readable storage device, a machine-readable storage substrate, a random or serial access memory device, or a combination of computer-storage mediums. Configuring one or more computers means that the one or more computers have installed hardware, firmware, or software (or combinations of hardware, firmware, and software) so that when the software is executed by the one or more computers, particular computing operations are performed. 
     The term “real-time,” “real time,” “realtime,” “real (fast) time (RFT),” “near(ly) real-time (NRT),” “quasi real-time,” or similar terms (as understood by one of ordinary skill in the art), means that an action and a response are temporally proximate such that an individual perceives the action and the response occurring substantially simultaneously. For example, the time difference for a response to display (or for an initiation of a display) of data following the individual&#39;s action to access the data can be less than 1 millisecond (ms), less than 1 second (s), or less than 5 s. While the requested data need not be displayed (or initiated for display) instantaneously, it is displayed (or initiated for display) without any intentional delay, taking into account processing limitations of a described computing system and time required to, for example, gather, accurately measure, analyze, process, store, or transmit the data. 
     The terms “data processing apparatus,” “computer,” or “electronic computer device” (or equivalent as understood by one of ordinary skill in the art) refer to data processing hardware and encompass all kinds of apparatus, devices, and machines for processing data, including by way of example, a programmable processor, a computer, or multiple processors or computers. The apparatus can also be, or further include special purpose logic circuitry, for example, a central processing unit (CPU), an FPGA (field programmable gate array), or an ASIC (application-specific integrated circuit). In some implementations, the data processing apparatus or special purpose logic circuitry (or a combination of the data processing apparatus or special purpose logic circuitry) can be hardware- or software-based (or a combination of both hardware- and software-based). The apparatus can optionally include code that creates an execution environment for computer programs, for example, code that constitutes processor firmware, a protocol stack, a database management system, an operating system, or a combination of execution environments. The present disclosure contemplates the use of data processing apparatuses with an operating system of some type, for example LINUX, UNIX, WINDOWS, MAC OS, ANDROID, IOS, another operating system, or a combination of operating systems. 
     A computer program, which can also be referred to or described as a program, software, a software application, a unit, a module, a software module, a script, code, or other component can be written in any form of programming language, including compiled or interpreted languages, or declarative or procedural languages, and it can be deployed in any form, including, for example, as a stand-alone program, module, component, or subroutine, for use in a computing environment. A computer program can, but need not, correspond to a file in a file system. A program can be stored in a portion of a file that holds other programs or data, for example, one or more scripts stored in a markup language document, in a single file dedicated to the program in question, or in multiple coordinated files, for example, files that store one or more modules, sub-programs, or portions of code. A computer program can be deployed to be executed on one computer or on multiple computers that are located at one site or distributed across multiple sites and interconnected by a communication network. 
     While portions of the programs illustrated in the various figures can be illustrated as individual components, such as units or modules, that implement described features and functionality using various objects, methods, or other processes, the programs can instead include a number of sub-units, sub-modules, third-party services, components, libraries, and other components, as appropriate. Conversely, the features and functionality of various components can be combined into single components, as appropriate. Thresholds used to make computational determinations can be statically, dynamically, or both statically and dynamically determined. 
     Described methods, processes, or logic flows represent one or more examples of functionality consistent with the present disclosure and are not intended to limit the disclosure to the described or illustrated implementations, but to be accorded the widest scope consistent with described principles and features. The described methods, processes, or logic flows can be performed by one or more programmable computers executing one or more computer programs to perform functions by operating on input data and generating output data. The methods, processes, or logic flows can also be performed by, and apparatus can also be implemented as, special purpose logic circuitry, for example, a CPU, an FPGA, or an ASIC. 
     Computers for the execution of a computer program can be based on general or special purpose microprocessors, both, or another type of CPU. Generally, a CPU will receive instructions and data from and write to a memory. The essential elements of a computer are a CPU, for performing or executing instructions, and one or more memory devices for storing instructions and data. Generally, a computer will also include, or be operatively coupled to, receive data from or transfer data to, or both, one or more mass storage devices for storing data, for example, magnetic, magneto-optical disks, or optical disks. However, a computer need not have such devices. Moreover, a computer can be embedded in another device, for example, a mobile telephone, a personal digital assistant (PDA), a mobile audio or video player, a game console, a global positioning system (GPS) receiver, or a portable memory storage device. 
     Non-transitory computer-readable media for storing computer program instructions and data can include all forms of permanent/non-permanent or volatile/non-volatile memory, media and memory devices, including by way of example semiconductor memory devices, for example, random access memory (RAM), read-only memory (ROM), phase change memory (PRAM), static random access memory (SRAM), dynamic random access memory (DRAM), erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), and flash memory devices; magnetic devices, for example, tape, cartridges, cassettes, internal/removable disks; magneto-optical disks; and optical memory devices, for example, digital video disc (DVD), CD-ROM, DVD+/−R, DVD-RAM, DVD-ROM, HD-DVD, and BLURAY, and other optical memory technologies. The memory can store various objects or data, including caches, classes, frameworks, applications, modules, backup data, jobs, web pages, web page templates, data structures, database tables, repositories storing dynamic information, or other appropriate information including any parameters, variables, algorithms, instructions, rules, constraints, or references. Additionally, the memory can include other appropriate data, such as logs, policies, security or access data, or reporting files. The processor and the memory can be supplemented by, or incorporated in, special purpose logic circuitry. 
     To provide for interaction with a user, implementations of the subject matter described in this specification can be implemented on a computer having a display device, for example, a CRT (cathode ray tube), LCD (liquid crystal display), LED (Light Emitting Diode), or plasma monitor, for displaying information to the user and a keyboard and a pointing device, for example, a mouse, trackball, or trackpad by which the user can provide input to the computer. Input can also be provided to the computer using a touchscreen, such as a tablet computer surface with pressure sensitivity, a multi-touch screen using capacitive or electric sensing, or another type of touchscreen. Other types of devices can be used to interact with the user. For example, feedback provided to the user can be any form of sensory feedback (such as, visual, auditory, tactile, or a combination of feedback types). Input from the user can be received in any form, including acoustic, speech, or tactile input. In addition, a computer can interact with the user by sending documents to and receiving documents from a client computing device that is used by the user (for example, by sending web pages to a web browser on a user&#39;s mobile computing device in response to requests received from the web browser). 
     The term “graphical user interface,” or “GUI,” can be used in the singular or the plural to describe one or more graphical user interfaces and each of the displays of a particular graphical user interface. Therefore, a GUI can represent any graphical user interface, including but not limited to, a web browser, a touch screen, or a command line interface (CLI) that processes information and efficiently presents the information results to the user. In general, a GUI can include a plurality of user interface (UI) elements, some or all associated with a web browser, such as interactive fields, pull-down lists, and buttons. These and other UI elements can be related to or represent the functions of the web browser. 
     Implementations of the subject matter described in this specification can be implemented in a computing system that includes a back-end component, for example, as a data server, or that includes a middleware component, for example, an application server, or that includes a front-end component, for example, a client computer having a graphical user interface or a Web browser through which a user can interact with an implementation of the subject matter described in this specification, or any combination of one or more such back-end, middleware, or front-end components. The components of the system can be interconnected by any form or medium of wireline or wireless digital data communication (or a combination of data communication), for example, a communication network. Examples of communication networks include a local area network (LAN), a radio access network (RAN), a metropolitan area network (MAN), a wide area network (WAN), Worldwide Interoperability for Microwave Access (WIMAX), a wireless local area network (WLAN) using, for example, 802.11 a/b/g/n or 802.20 (or a combination of 802.11x and 802.20 or other protocols consistent with the present disclosure), all or a portion of the Internet, another communication network, or a combination of communication networks. The communication network can communicate with, for example, Internet Protocol (IP) packets, Frame Relay frames, Asynchronous Transfer Mode (ATM) cells, voice, video, data, or other information between network nodes. 
     The computing system can include clients and servers. A client and server are generally remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other. 
     While this specification contains many specific implementation details, these should not be construed as limitations on the scope of any invention or on the scope of what can be claimed, but rather as descriptions of features that can be specific to particular implementations of particular inventions. Certain features that are described in this specification in the context of separate implementations can also be implemented, in combination, in a single implementation. Conversely, various features that are described in the context of a single implementation can also be implemented in multiple implementations, separately, or in any sub-combination. Moreover, although previously described features can be described as acting in certain combinations and even initially claimed as such, one or more features from a claimed combination can, in some cases, be excised from the combination, and the claimed combination can be directed to a sub-combination or variation of a sub-combination. 
     Particular implementations of the subject matter have been described. Other implementations, alterations, and permutations of the described implementations are within the scope of the following claims as will be apparent to those skilled in the art. While operations are depicted in the drawings or claims in a particular order, this should not be understood as requiring that such operations be performed in the particular order shown or in sequential order, or that all illustrated operations be performed (some operations can be considered optional), to achieve desirable results. In certain circumstances, multitasking or parallel processing (or a combination of multitasking and parallel processing) can be advantageous and performed as deemed appropriate. 
     Moreover, the separation or integration of various system modules and components in the previously described implementations should not be understood as requiring such separation or integration in all implementations, and it should be understood that the described program components and systems can generally be integrated together in a single software product or packaged into multiple software products. 
     Accordingly, the previously described example implementations do not define or constrain the present disclosure. Other changes, substitutions, and alterations are also possible without departing from the spirit and scope of the present disclosure. 
     Furthermore, any claimed implementation is considered to be applicable to at least a computer-implemented method; a non-transitory, computer-readable medium storing computer-readable instructions to perform the computer-implemented method; and a computer system comprising a computer memory interoperably coupled with a hardware processor configured to perform the computer-implemented method or the instructions stored on the non-transitory, computer-readable medium.
