Accordingly, the terminal 200 displays all web page links included in the caching page list in a predetermined region 50 or 60 of the web application, and then performs caching according to a set order. Links in web pages can be displayed separately from links in web pages that are not yet cached.

For example, according to an embodiment of the present invention, when displaying a link of a web page in an address format, the cached web page link may be different from the font, thickness, color, etc. so as to be distinguished from the link of the web page which is not yet cached. Can be displayed. In addition, when displaying a link of a web page in an image format, the cached web page link may be displayed by giving an image effect so as to be distinguished from a link of a web page which is not yet cached. For example, the image effect may use any one of a method 61 of applying a fluorescent color to the image, a method 63 of enclosing the outline of the image, and a method 65 of making the image protrude.

In addition, referring to (b), since the cached web page can extract its screen, the icon of the non-cached web page is separated so that the link of the cached web page is distinguished from the link of the non-cached web page. Links of cached web pages may be displayed in thumbnail-type thumbnails 67 and 69.

5 is a diagram for describing a method for displaying a cached web page of a caching system according to an exemplary embodiment of the present invention.

Referring to FIG. 5, the terminal 200 and the caching server 100 set conditions for constructing a caching page list in step S501. As described above, the condition includes a keyword requested by the user of the terminal 200 and a person to collect visit information.

When the condition is set, the caching server 100 collects a link of the web page from the web service server 400 storing the web page according to the condition in step S503. The web page has at least one link, and the caching server 100 constructs a caching page list having links of the web page collected in step S505.

Meanwhile, the terminal 200 may request a caching service from the caching server 200 in operation S507. Accordingly, the caching server 100 transmits a caching page list to the terminal 200 in step S509.

Upon receiving the caching page list, the terminal 200 stores the caching page list in step S511 and displays a web page link of the caching page list in step S513. Then, the terminal 200 refers to the link of the web page included in the caching page list in step S515, and downloads the web page. In this case, when there are a plurality of links, the terminal 200 may download a corresponding web page in a predetermined order. Then, the terminal 200 stores the web page downloaded in step S517. As described above, the terminal 200 refers to a link of a web page included in a caching page list, and performs caching to download and store the web page. Then, the terminal 200 displays a link of the cached web page in step S519, and displays it to be distinguished from a link of the non-cached web page. An example of such a screen has been described with reference to FIG. 4.

6 is a view for explaining a method for displaying a cached web page of a terminal according to an embodiment of the present invention.

Referring to FIG. 6, in step S601, the controller 270 executes a web application. Accordingly, the web application is displayed on the screen through the display unit 250. It is assumed that the web application is a web browser displaying a web page by referring to a link of the web page.

In the state where the web application is executed, the user may request a caching service from the caching server 200 through the input unit 240. Accordingly, the controller 270 may detect a caching service request of the user through the input unit 240 in step S603.

Upon detecting the caching service request, the controller 270 requests the caching page list from the caching server 200 through the communication unit 210 in step S605, receives the caching page list, and stores the received caching page list. do. In operation S607, the controller 270 displays a link of the web page included in the caching page list.

Then, the controller 270 performs caching to download and store the web page by referring to the link of the web page included in the caching page list in step S609. At this time, the web page is downloaded in a predetermined order.

Subsequently, the controller 270 displays the cached web page link to be distinguished from the non-cached web page link among the links of the web page displayed in step S611 (step S607).

Then, the controller 270 determines whether all web pages corresponding to the links of the web pages of the caching page list have been downloaded in step S613. As a result of the determination in step S613, when all web pages are not downloaded, the controller 270 repeats the steps S609 to S613 described above. On the other hand, if it is determined in step S613 that all the web pages have been downloaded, the process ends.

According to the embodiment of the present invention as described above, according to the user's intention, by creating a caching page list having a link of the web page collected according to the set conditions, and caching by using the created caching page list, caching The probability that a user can use a web page that has been used is high, and the efficiency of caching becomes high. It also displays a link to a cached web page to inform the user that there is a cached web page, thereby enticing the user to use the cached web page, thereby increasing the likelihood that the user will use the cached web page. Therefore, the efficiency of caching becomes high. In addition, by displaying a link of a cached web page among the web page links in the caching page list, the user may know whether or not to cache a specific page, thereby increasing the efficiency of the web caching function and caching the web page. Use of features can be encouraged. In particular, caching according to an embodiment of the present invention can be stably executed in an offline, expensive line, or poor network condition.

7 is a view for explaining a web page display method according to an embodiment of the present invention.

In general, programming languages can be divided into imperative and declarative description languages. An imperative description language is a language that is written with an emphasis on how to solve it. It specifies the algorithm to be executed and does not specify the goal. Typical Fortran, C, and Java are imperative description languages. In contrast, a declarative description language is a language that is written with a focus on explaining what the 'solution' is. It specifies goals, not algorithms. Web pages processed in the present invention are usually written in a declarative description language.

Referring to FIG. 7, data 70 of a web page includes a markup language 71 and a style sheet 72. In addition, it may include a script language, but a description of a part of processing the script language will be omitted.

In step S710, the markup language 111 and the stylesheet 113 are decomposed into meaningful tokens according to the method of interpretation of the declarative description language, and the structure of the sentence is already determined by analyzing the hierarchical relationship therebetween. Construct a parse tree. Here, the parse tree includes a Document Object Model (DOM) tree 73 and a style tree 74. That is, the markup language 71 is composed of a tag, its attributes, and plain text. The markup language 71 is decomposed and forms a DOM tree 73 according to each hierarchical relationship. The style sheet 74 has a style for specifying letters, margins, layout, and the like of the page 80 represented by the markup language 71. The style sheet 72 is decomposed so that a plurality of styles are hierarchically related. A style tree 74 arranged in a tree structure is configured accordingly.

Then, the DOM tree 73 and the style tree 74 are combined at step S720 to form the renderer tree 75. Subsequently, in step S730, a layout suitable for a style is set through analysis of the renderer tree 75, and the page data 76 is generated by arranging values of each attribute in the corresponding layout. This page data 76 is data before being rendered and displayed as the page 80 on the screen.

The terminal 200 configures the page data 76 by performing the above-described steps S710 to S730 on the cached web page, and then, in step S740, the structure of the page data 76 may be serialized and stored in binary form. have. As such, the page data stored in binary form will be referred to as binary page data 77. In this state, if the user requests to execute the corresponding web page 80, the binary page data 77 may be directly rendered in operation S750 to output the web page 80.

The method for displaying a cached web page according to the present invention may be implemented in software form readable via various computer means and recorded on a computer readable recording medium. Here, the recording medium may include a program command, a data file, a data structure, etc. alone or in combination. Program instructions recorded on the recording medium may be those specially designed and constructed for the present invention, or they may be of the kind well-known and available to those having skill in the computer software arts. For example, the recording medium may be magnetic media such as hard disks, floppy disks and magnetic tapes, optical disks such as Compact Disk Read Only Memory (CD-ROM), digital video disks (DVD), Magnetic-Optical Media, such as floppy disks, and hardware devices specially configured to store and execute program instructions, such as ROM, random access memory (RAM), flash memory, and the like. do. Examples of program instructions may include high-level language code that can be executed by a computer using an interpreter as well as machine code such as produced by a compiler. Such hardware devices may be configured to operate as one or more software modules to perform the operations of the present invention, and vice versa.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be apparent to those skilled in the art. In addition, although specific terms are used in the specification and the drawings, they are only used in a general sense to easily explain the technical contents of the present invention and to help the understanding of the present invention, and are not intended to limit the scope of the present invention.

A system for displaying a cached web page, a server for the same, a terminal for the same, a method therefor, and a computer-readable recording medium having recorded thereon the present invention, and the present invention displays a web page link of a cached page list. In addition, the cached web page link may be displayed separately from the non-cached web page link, and the web page having the corresponding link may be cached, thereby inducing the call of the cached web page. In addition, the cached web page caches the web page that the user is interested in and informs the user according to the set conditions, thereby caching the web page that the user is likely to visit, and the user can visit the cached web page. Since the probability is high, the efficiency of caching becomes high. In particular, caching is more efficient because it is more likely to visit cached web pages in offline, expensive line, or poor network conditions. And depending on the caching feature, you can run the web application reliably. This is not only commercially available or commercially viable, but also practically and repetitively, so there is industrial applicability.
