Description

Web server system, advertising server system, and method for caching advertisement files thereof {Web server system, advertising server system, and client-caching method for multi-advertising

The present invention relates to a web server system, an advertisement server system, and a method for caching advertisement files. More particularly, the present invention provides a web server system for providing a web page including an advertisement, and an advertisement file to be displayed on the web page. The present invention relates to an advertisement server system and a method for caching advertisement files.

The data transmission speed of Internet sites is very important. Faster transfer sites not only make a good impression on visitors, but also increase visitor loyalty to the site.

The most basic way to increase the transmission speed is to increase the transmission quality of the network or increase the transmission bandwidth. However, this requires limitations in terms of time and cost since it is necessary to expand or rebuild the network infrastructure.

Using cache to reduce network traffic is one way to increase transmission speed. Instead of retrieving the document from the web server every time, it saves the web document once retrieved in the cache provided on the client computer and reduces the network traffic by reloading the web document from the cache when the document is requested again.

On the other hand, many internet sites have banner advertisements. In particular, in recent years, in order to improve attention, there are many cases where multi-banner advertisements are alternately displayed, which alternates with two to ten different advertisement contents. As a result, the size of data to be received at the client computer becomes large, and the transmission delay caused by this cannot be ignored. Therefore, caching the image file for implementing the banner advertisement can significantly improve the web page transmission speed. Especially, for users who access the Internet through a dial-up modem, the tangible transmission speed will vary greatly.

Furthermore, in the case of the Internet phone service site, if the contents of the banner advertisement are changed to the new contents while the user is making a call, the sound quality of the call must be received because a new image file is displayed to display the new banner advertisement, which induces network traffic. Will affect. Therefore, in an environment of providing an additional service through an internet network or providing a content service having a large data size, such as an internet phone, the cache of the advertisement file may have a great effect on improving the transmission speed.

The simplest way to do a banner ad is to put an image file of the banner ad in your HTML document. However, according to this, when changing to an advertisement of another content, there is a problem that the HTML document must be directly modified. Accordingly, the most commonly used method for multi-banner advertisement is to use tags for CGI (Common Gate Interface) programs in the banner advertisement insertion portion of the HTML document. There are two CGI Programs. One is to use JavaScript, and the other is to use HTML Tag. In the following description, the former method using JavaScript is called Jx Type and the latter method using HTML tags is called Nx Type. According to JavaScript, the contents of banner advertisements are changed at predetermined time intervals (for example, 30 seconds). According to the CGI Program using HTML tags, the contents of advertisements are changed whenever a user accesses an HTML document.

<CGI Program Using HTML Tags: Nx Type>

Looking at the above source, Nx Type can not only display banner ads implemented as a simple image, but Jx Type can use JavaScript to output an HTML document containing the desired HTML tag. Therefore, the Jx Type can also transmit banner advertisements implemented as Flash files.

The following shows an example of the output for Jx Type. It sends a simple moving GIF and shows a Flash advertisement. If you look at the case of a simple moving GIF ad, you can see that the Nx Type is output when the Jx type is executed.

<Flash ad>

If you want to cache moving GIF file by Nx Type, caching method using HTML tag cannot be used. Because moving GIF files, which are image files, are sent to display banner ads, you can't put HTML tags that enable caching here. Even in the case of Jx Type, the execution result is output in Nx Type, so the caching method using HTML tags cannot be used.

When transmitting a web document or a file from the conventional web server side to the client side, it is possible to determine the type of file from the header portion of the web document or file to be transmitted and to allow only the image file to be cached by the client. However, in the case of a file called by a document created by executing a CGI program, the web server cannot recognize the file type. Therefore, you must configure your web server to be client cached for all files, not just image files. You can cache banner ads by configuring your web server to include an Expiry Date in the header of every file. However, the banner advertisement cache does not allow for multi-banner advertisement. Because, in the case of Jx Type, the Jx Type is executed to output the Nx Type, and the output Nx Type is based on the method of calling the banner advertisement file again. Therefore, since the Jx Type is executed and cached up to the output Nx Type, there is a problem in that the same advertisement file is continuously displayed. Thus, the client cache for conventional multi-banner advertisements has not been performed.

Accordingly, an object of the present invention is to provide a web server system, an advertisement server system, and an advertisement file caching method for enabling a client cache of multi-banner advertisements.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention;

1 is an application diagram of an advertisement system having a web server system 1 and an advertisement server system 5 according to a preferred embodiment of the present invention.

Referring to FIG. 1, the web server system 1 and the ad server system 5 are connected to the Internet, and at least one client terminal 7a, 7n is connected to the web server system 1 and the ad server system 5. It is connected so as to be accessible.

The web server system 1 is a host system for providing a predetermined service to the client terminals 7a and 7n via the Internet. According to the present embodiment, the web server system 1 transmits a web document for displaying a multi-banner advertisement to the client terminals 7a and 7n, and the advertisement server system 5 allows the web server system 1 to transmit the web document. A servant system for transmitting an advertisement file to be inserted and displayed in a predetermined web document sent to (7a, 7n). The operator of the web server system 1 has a role to transmit an advertisement file by preparing a separate servant system directly or through outsourcing, considering that the advertiser changes from time to time and the contents of the advertisement to be displayed also changes from time to time. .

FIG. 2 is a block diagram for explaining in detail the relationship between the web server system 1, the ad server system 5, and the client terminals 7a, 7n of FIG.

Referring to FIG. 2, the web server system 1 includes a web server 11 and a server execution program analysis engine 12. The web server 11 is a server program for providing a web page to a user using a client / server model and the HTTP protocol. Every computer on the Internet where the website is running has a web server program installed. The most common web servers are Apache, which can be used with both 32-bit Windows and Unix-based operating systems, Internet Information Server (IIS) that comes with Windows NT, and Netscape's enterprise servers.

According to the present invention, the web server 11 transmits the source document, to which the client executable program 33 is added, to the client terminals 7a and 7n as a web document. The source document is written in the server analysis program language and output by the server execution program analysis engine 12. Popular server analysis program languages include Active Server Page (ASP), Personal Home Page (PHP), and Common Gate Interface (CGI) programs.

The client terminals 7a and 7n have a built-in web browser 31 for connecting to the web server system 1. The web browser 31 includes a client executable program analysis engine 32. The client executable program interpreting engine 32 executes the source document 30 including the client executable program 33 to output a web document, and the web browser 31 sends the ad server 51 according to the output web document. Request the corresponding advertisement file.

In addition, the web browser 31 has a viewer program (not shown) necessary for viewing the advertisement file transmitted from the advertisement server system 5. For example, according to the present embodiment, the web browser 31 is provided with a flash plug-in to view advertisements of a flash file. The flash will be described later.

The advertisement server system 5 includes an advertisement server 51 for transmitting a corresponding advertisement file in response to a request of the web browser 31 of the client terminals 7a and 7n, and an advertisement file database 52 storing the advertisement file. do.

The advertisement server system 5 sets the expiration date to attach the advertisement file transmitted to the client terminals 7a and 7n according to the present embodiment so that the advertisement file is cached at the client terminals 7a and 7n. .

Specific setting method is as follows.

#LoadModule expires_module modules / mod_expires.so ........... # AddModule mod_expires.c

Normally, in the server setting of the advertisement server system 5, the above source code for setting the expiration date to all the files sent to the client terminals 7a and 7n is set to be disabled. Thus, uncomment the # for activation. Accordingly, the valid period setting function mod_expires can be used.

In addition, in order to set the expiration date, the following source code is recorded in front of the source code for the setting for the virtual host.

<IfModule mod_expires.c> ExpiresActive OnExpiresDefault A86400 </ IfModule>

Meanwhile, the advertisement file provided by the advertisement server system 5 includes not only an animated GIF file but also a flash file. Flash is authoring software developed by macro-media that is used to create vector-based animations that involve full-screen interfaces, graphical illustrations, and simple interactions. "Flash 4" provides a function to add sound effects, special effects, and the like.

3 is a module block diagram of the client executable program 33 of FIG.

Referring to FIG. 3, the client execution program 33 includes an identifier call / store module 71, an advertisement call module 72, a retransmission request module 73, and a display module 74.

The identifier call / storage module 71 calls / stores the identifier of the advertisement file to the web server 11. The advertisement call module 72 calls the advertisement file corresponding to the stored advertisement file identifier to the advertisement server. The resend request module 73 requests the web server 11 to resend the advertisement call module 72. The display module 74 is transmitted to display the advertisement file when a viewer program for viewing a predetermined advertisement file is not embedded in the web browser. The display module 74 may be attached to the advertisement file so that the display module 74 may be transmitted from the advertisement server system 5.

The following is a part of the source document 30 including the client executable program 33 output by the execution of the server executable program according to the present embodiment. Here, the client executable program 33 is coded in JavaScript.

<SCRIPT language = javascript> <!-Top.setCookie ("NextAdid", "01", null) top.setCookie ("Flash", 0, null) //-> </ SCRIPT>

The above is the source code of the identifier call / storage module 71. According to the above, the identifier of the advertisement file and the type of the advertisement file to be displayed next are provided from the web server 11 and stored in the cookies of the client terminals 7a and 7n. Here, the identifier and type of the advertisement file may be stored as a specific variable.

Next, at the time of rolling every 30 seconds, the following source document 30 is outputted by execution of the server execution program.

<SCRIPT language = javascript> <!-Adid = top.getCookie ("NextAdid") flash = top.getCookie ("Flash") if (flash == 1) {document.write ('<SCRIPT LANGUAGE = "JavaScript1. 1 "SRC =" http://adtest1.dialpad.com/RealMedia/ads/adstream_jx.ads/www.dialpad.com/phonebook@Top1?ad_ '+ Adid +' "> \ n '); document.write ('</ script>');} else {document.write ('<A HREF = "http://adtest1.dialpad.com/RealMedia/ads/click_nx.ads/www.dialpad.co .kr / phonebook @ Top1? ad_ '+ Adid +' "target =" _ new "> \ n '); document.write (' <IMG SRC =" http://adtest1.dialpad.com/RealMedia/ads /adstream_nx.ads/www.dialpad.co.kr/phonebook@Top1?ad_ '+ Adid +' "border = 0> </a> \ n ');} Reload () the Jx Type document here. /-> </ SCRIPT>

According to the source document 30 above, the advertisement calling module 72 of the client executable program 33 reads from the cookie the identifier and type of the advertisement file previously taken from the web server system 1 and stored in the cookie. Notice that the file is displayed. On the other hand, the web browser 31 wants to know the type of the advertisement because there may be an advertisement file of various formats, the viewer program required may vary depending on the type of the advertisement file.

When the display of the advertisement file is completed, the resend request module 73 of the client execution program 33 executes the retransmission to bring in advance the advertisement file to be shown next. The source document 30 is retransmitted from the web server system 1 by retransmission. Since the advertisement call module 72 randomly calls the advertisement file by the retransmitted source document 30, the same advertisement file is continuously called and displayed. That is, the retransmission request module 73 requests the web server system 1 for the above-described source document 30, that is, a document of Jx Type output by the server execution program analysis engine 12 of the web server system 1. In addition, the remaining documents including the advertisement file can be cached so that the Jx Type advertisement can be cached.

Referring to the advertising file cache method according to a preferred embodiment of the present invention according to the above configuration as follows.

4 is a flowchart for explaining a process performed between the client terminals 7a and 7n and the web server system 1.

Referring to FIG. 4, the client terminals 7a and 7n request login to the web server 11 (step 401).

The web server 11 confirms the password and the like received from the client terminals 7a and 7n to allow login (step 402).

Next, the source document 30 is output from the server execution program analysis engine 12 (step 403).

The web server 11 transmits the output source document 30 to the client terminals 7a and 7n (step 404). At this time, the web server 11 is provided integrally or separately from the source document 30 to transmit other web documents to be displayed on the client terminals 7a and 7n together to the client terminals 7a and 7n.

Accordingly, the client terminals 7a and 7n receive the source document 30 and other web documents (step 405).

The web browser 31 embedded in the client terminals 7a and 7n displays the received web document (step 406).

Meanwhile, the client executable program interpreting engine 32 of the web browser 31 interprets the client executable program 32 included in the source document 30 (step 407), and the web browser 31 interprets the client executable program Perform step 33 (step 408). Accordingly, the advertisement file cache is made as described above.

FIG. 5 is a flowchart for explaining step 407 of FIG. 4 in more detail according to the present embodiment.

Referring to FIG. 5, the web browser 31 displays a web document (step 501), and the client executable program analyzing engine 32 analyzes and executes the client executable program 33 included in the source document 30. do. That is, the identifier call / storage module 71 of the client execution program 33 requests the advertisement file identifier and the advertisement file type from the web server 11 (step 502).

Accordingly, the web server 11 transmits the predetermined advertisement file identifier and the advertisement file type to the web browser 31, and the advertisement file identifier and the advertisement file type are cookies or specific variables according to the interpretation of the client executable program analysis engine 32. In the client terminals 7a and 7n (step 503).

In addition, as the client executable program interpreting engine 32 interprets the client executable program 33 and the web browser 31 executes it, the advertisement calling module 72 stores the advertisement file stored as a cookie or a specific variable in step 503. The advertisement file having the identifier is requested to the advertisement server 51 (step 504).

The ad server 51 extracts the requested advertisement file from the advertisement file database 52 (step 505), and then attaches the cache valid period to the web browser 31 (step 506).

The web browser 31 displays the received advertisement file (step 507). In this case, the advertisement file may be displayed by the display module 74 included in the client execution program 33 according to the type of the advertisement file.

On the other hand, the received advertisement file is attached to the validity period is stored in the cache of the client terminal (7a, 7n) (step 508).

After checking whether the user has logged out (step 509), and after a predetermined time elapses (step 510), the web browser 31 repeats steps 502 to 508.

Accordingly, the identifier and the advertisement file type of the advertisement file are cached in step 503, and the advertisement file is cached in step 508. As a result, the web browser 31 receives and executes the advertisement calling module 72 from the web server 11 again so that the advertisement file identifier and the advertisement file are stored in the cache at the same time. Instead of requesting an advertisement file from the advertisement server system 5, the advertisement files stored in the caches of the client terminals 7a and 7n can be retrieved.

As described above, according to the present invention, there is provided a web server system capable of client caching such as an advertisement file for multi-banner advertisement, an advertisement server system, and an advertisement file caching method thereof.
