Description

Method for setting up and using preference in web browser}

The present invention relates to a method for setting and using a personal code of a web browser, and in particular, improves a response speed when using a web page in an environment with a poor network bandwidth, and supports a PDA (Portable Display Adapter) / TV. The present invention relates to a method of setting and using a personal code of a web browser, which is suitable for improving efficiency and response speed when using the web in an environment in which the browser expresses poorly.

In general, the Internet is an international network of computers or servers for sharing educational, economic, and commercial information, and refers to a type of computer network. All computers connected to the Internet use TCP / IP (Transmission Control Protocol / Internet Protocol) as a standard protocol, which enables information exchange between many different types of computer systems. And the Internet provides many different services-Telnet, E-Mail, FTP, Gopher, WAIS, Archie, WWW, etc.-to share information around the world.

The World-Wide Web (WWW) is the most popular information service on the Internet in recent years. It is not only text information but also various sounds such as sound, pictures, and video. Not only can you transfer information at once, but even beginners who are new to the Internet can easily move from place to place with just a mouse.

The Web connects information on the Internet through a technology called hypertext or hypermedia, which makes it easy for users to find relevant information. Hypertext refers to information that contains links to other information as text information. Hypermedia refers to information including not only simple text but also links to various types of information such as pictures, voices, and moving images. Point. Thus, a user can click on a link on the screen to receive a new document in a Uniform Resource Locater (URL) specific to the link.

Like many other Internet services, the Web uses a client / server system. Web clients (hereinafter referred to as "web browsers") and web servers are applications that exchange data through standard protocols. HTTP (HyperText Transfer Protocol) is one of the standard protocols of the web, and is used for communication between a web client and a web server to exchange web documents in a hypertext or hypermedia structure. A web document is a document written using HTML (Hypertext Markup Language), which is plain ASCII text with a tag. Tags are inserted in the middle of text to display text on the screen or to link to other web documents.

Here, the web page is sent to the browser in the form of frames, advertisements, images, pop-up windows, and other objects created by the original author. The browser is then defined to render exactly as it is if the browser has the ability to represent them.

Among the prior arts, there is a technique of setting the browser (for example, Internet Explorer) not to show each image, video, sound, and the like.

However, since this is not a structure for parsing the contents expressed in the structure, it is impossible to control the pop-up window or control the frame. In addition, there was a disadvantage in that it cannot support various types such as plug-in or ActiveX object.

In addition, other browsers, such as Netscape, give you no control over the presentation of Web page content.

There are also products that block some banner ads, but only control over the image, other controls are not possible (and some pop ups are included), and must be installed on the client. And, there is a inconvenience in the installation process, there was a problem that only Internet Explorer (Internet Explorer) is supported.

Therefore, it is difficult to expect the setting of the preference to be reflected in the conventional technology in the Windows CE environment such as PDA, Web TV, or Linux environment (Netscape).

This will be described in detail by dividing the following image, various objects, frame size, and pop-up window into three parts.

Images and Various Objects-Even if there are objects that are not required by the user, there is no method of selectively loading them according to the type. Therefore, there is a problem in that network costs must be unreasonably impaired and the response speed is lowered. This problem can be a major complaint, especially for users using low speed communication lines.

Regarding frame size-Regular web pages use a lot of structures called frames to improve screen layout. However, at a specified resolution (eg, 800x600), it is well represented, but at lower resolutions (eg, 640x480-Web TV, etc.), an important text is usually located in the lower right corner, so the size that can be expressed is reduced.

Pop-up Window Related-Pop-up windows can be useful in some cases, but they are inconvenient for pop-ups that appear irrelevant to the user's intention because of the inconsistency of the screen flow and the increasing number of sites that pop-up windows too often.

On the other hand, Figures 1 to 3 is a view showing a method of providing an HTML document by the web server of the prior application No. 10-1999-00211607.

1 is a block diagram showing a transmission path between a web browser and a web server to which a conventional method is applied.

Therefore, the web browser 110 requests the HTML document of the place specified in the URL to the web server 120 using the HTTP protocol, and the web server 120 searches for the requested HTML document and the web browser 110. To provide. The web browser 110 shows the provided HTML document to the user through the user's display device in accordance with the format.

In this case, as shown in FIG. 1, the HTML document transmitted from the web server 120 to the web browser 110 is transmitted without modification as it is stored in a place specified in the URL regardless of various computing environments of the user.

2 is a conceptual diagram of a method of providing an HTML document by a conventional web server.

Thus, the web document providing system includes a web browser 110a to 110d, a web server 120, and an HTML converter 220.

HTTP is a standard protocol of the web for transmitting HTML documents between the web server 120 and the web browsers 110a to 110d. The information transmitted by the web is divided into an HTTP header and a document body. Can be. The HTTP header is based on MIME (Multipurpose Internet Mail Extensions), which is the Internet's standard protocol for multimedia electronic mail on the Internet. In the HTTP header, not only binary information but also a method for opening an HTML document, information for confirming an HTML document format, and non-standard information promised (encoded) between the web server 120 and the web browsers 110a to 110d can be transmitted. Do. Typically, the HTTP header contains information about the version of HTTP utilized, response status, current date and time, required document-related information, etc., and the document body indicates the requested HTML document.

The plurality of web browsers 110a to 110d contact the web server according to the protocol specified in the URL, and send a request request for specifying a URL of a desired HTML document. URL is a standard information location representation method for uniformly representing the location of a large number of information on the Internet. URL on the web is used to indicate the location of a web document on a web server.

At this time, the web browser promises to predetermine information about the computing environment of the user, for example, display color / mono, display text mode / graphic mode, keyboard presence, speaker / microphone presence, window environment presence, monitor presence information, and the like. According to (encoding), it is sent in the HTTP header to the web server 210.

The web server 120 which is requested to provide the HTML document from the web browser reviews the computing environment information of the user from the HTTP header. The web server then deletes the useless tags or contents from the HTML document obtained from the URL in accordance with the user's computing environment information reviewed using the HTML converter 220, or converts the content into a document form accessible to the user. Let's do it.

The web server 120 transmits the HTML document converted according to the computing environment of the user to the web browsers 110a to 110d so as to be displayed on the screen according to the format of the HTML document.

3 is a flowchart illustrating a method of providing an HTML document by a conventional web server.

Thus, the web server 120 promises (encodes) information about the web browsers 110a to 110d and the computing environment of the user in advance (310). For example, it means to convert the presence or absence of a speaker, the color of the monitor, etc. into ASCII data for one-to-one correspondence, and to promise mutual recognition. When the web server 120 is requested to provide a document from the web browsers 110a to 110d, the web server 120 determines whether the document is a request for providing a document from a web browser loaded with predetermined information about a computing environment (320). The computing environment information of the user who has been previously promised (encoded) in the HTTP header is read in the HTTP protocol transmitted from 110a to 110d (360).

If the web browser does not include information about the computing environment of the user in the HTTP header, the web server 120 requests the computing environment information of the user from the web browsers 110a to 110d (330).

When the web server 120 requests the computing environment information of the user from the web browser, the web server 120 sends a page containing the FORM for displaying the computing environment information to the web browsers 110a to 110d to the web browsers 110a to 110d. To display it on the user's display device. In this case, the display device and the input means must be included in the computing environment of the user. The user enters his computing environment in the form FORM of the page sent from the web server 120 and sends it back to the web server 120. The page on which the form requesting the computing environment information is loaded has a format in which the web server 120 allows the user to indicate whether the computing environment item is provided on the form. Or, it can take a flexible form, allowing users to enter their computing environment directly into a form. The user may not transmit his or her computing environment information to the web server by leaving the form empty, in which case the web server 120 provides the HTML document without modification (350).

If information about the computing environment of the user is sent to the web server 120 by the HTTP header or through the computer environment request page sent by the web server, the web server 120 reads the user's computing environment information from the review (360). In operation 370, the HTML document at the place specified in the URL is converted to the reviewed computing environment information through the HTML converter (380). The HTML document converted by the web server 120 is transmitted to the web browsers 110a to 110d through the HTTP protocol (390).

However, this conventional technology processes the content expressed in accordance with the client's ability at the server and generates the content for the client every time at the request of the client, whereas the content to be sent from the server to the client is created separately. There was a problem that the server load greatly increased because it had to pay, and above all, only the contents in the server to which this technology was applied could be processed and could not be applied to the existing existing website. Therefore, only the contents produced by the client in the client's own judgment based on the user's preferences to generate the HTML that fits the preferences, but could not solve the problem of network load and inefficiency of the screen size.

As such, the conventional technologies provide more control over the less important or unnecessary parts of the existing page structure in a situation where the network environment is poor or the screen resolution is poor. And the web page is created based on the parent environment, causing unnecessary network load and inefficiency of the screen size. Pop-up windows and heavy ads are included regardless of the user's intention. There were problems that floated.

Accordingly, the present invention has been proposed to solve the conventional problems as described above, an object of the present invention is to improve the response speed when using a web page in an environment of poor network bandwidth, and to express the browser, such as PDA / TV The purpose of the present invention is to provide a method of setting and using a personal code of a web browser that can improve efficiency and response speed when using a web in a poor environment.

Hereinafter, with reference to the accompanying drawings an embodiment according to the present invention, the technical idea of the method of setting and using the personal code of the web browser as follows.

5 is a flowchart illustrating a method of setting and using a personal code of a web browser according to the present invention.

As shown therein, a first step (ST11 to ST14) of determining whether a web document that the user wants to view in the proxy server 10 is cached after the user accesses the proxy server 20; If the web document is not cached, a second step (ST15 to ST17) of parsing, processing, and storing the web document using a proxy function; It includes a third step (ST18 ~ ST22) to recompose the code in the HTML document actually downloaded after the second step to the data of the script program on the basis of the stored personal preferences (Preference).

In the first step, the user accesses the proxy server 20 (ST11); Recording the personal preferences on the personal setting page after the access and storing the setting contents as a cookie (ST12); After storing as the cookie, the user selects or inputs a web page to be viewed on the proxy server 10, and then determines whether the document of the web is cached (ST13) (ST14).

In the above-mentioned second step, the syntax for opening a pop-up window including a frame, an image, an object, an applet, an embedded tag, or for JavaScript is included. Finding data including Syntax); Finding the data and then replacing the original tag or code portion with an indication of a specified special syntax or marking the location; Allowing the original HTML data up to the location after the display to be encoded according to an escape rule of JavaScript; And all the replaced data after the encoding is assigned to a JavaScript variable.

In the above, the third step may include: transmitting the processed web document to the browser (ST18); Converting the data in the processed code after the transmission into a string array based on a specified syntax (ST19); A step (ST20) of converting, in the browser, all string arrays into HTML strings sequentially escaped based on a setting in a cookie based on a delimiter in the browser; A step of making the string into an unscape, and writing a web document from the processed string (ST21); And a step ST22 of forming a new page from the newly written document after the writing.

In the third step, when recombining an image and an object in a personal symbol, a user may select a predefined type or file format through setting so that a web document is created by dividing the content to be expressed and the content not to be expressed in the document. Process to recombine.

In the third step, when recombining an image and an object in a personal symbol, the proxy server 20 makes the image several different quality and size, and uses a small file size at low quality according to the user's image selection type. Or recombine using the original image.

In the third step, when recombining the frame size by the individual symbol, the frameset is parsed to find a body frame including the body, and the body frame selectively takes up the entire screen size or returns to the original frame size. Recombine in a web browser so that it can be restored.

In the above-mentioned third step, when recombining the frame size by the personal symbol, the part about the original frame size is included in the program source descending to the browser as a variable, and the variable for the frame size if there is a personal symbol setting for the frame hiding. In order to make the body occupy 100% of the screen and put 0% in the remaining frame size, the body is reassembled so that only the body frame is shown on the screen.

In the third step, when recombining the pop-up window by the personal symbol, if the user does not want to display the pop-up window, a comment processing process for generating a window from the JavaScript program source sent to the web browser 10 To reassemble the pop-up window.

The operation of the method of setting and using the personal code of the web browser according to the present invention configured as described above will be described in detail with reference to the accompanying drawings.

4 is a conceptual diagram between a web browser and a proxy server to which the present invention is applied.

Where reference numeral 10 is a web browser, 20 is a proxy server, and 30 is the original source site.

The present invention can be used to receive documents from all web sites in one place through a proxy server (hereinafter referred to as Intelligent Proxy), and to parse and encode the original web page through server-side processing. In addition, the code in the downloaded HTML document can be divided into parts that allow recombination based on stored personal preferences.

Therefore, the present invention excludes the way in which the program is installed on the client and controls the expressed content, and adopts a structure that allows the user to recombine the content to be expressed using only the function of the general browser (JavaScript processing capability). The settings can be reflected regardless of the type.

In addition, by providing intelligence to the proxy function of the proxy server 20, the HTML document to be displayed in the browser by dividing the frame structure, pop-up window, and various objects is displayed by logic in the browser. We have created a program source (in JavaScript) that can be instantaneously processed.

The web document arriving at the proxy server 20 through the proxy function of the proxy server 20 may be recombined in the browser through parsing of a frame structure, an image or other object, a pop-up window, or the like included in the original document. It is decomposed so that it can be stored as a data string in JavaScript code.

The JavaScript code is executed in the browser and recombined through the settings stored in the cookie.

* Processing of images and various objects-The user can select a predefined type or file format through settings, and process the web document to be created by distinguishing the content to be expressed and the content not to be expressed in the document.

Also, in case of low expressive ability of device such as PDA, the intelligent proxy server makes the image in several different quality and size, and selects the use of small file size or original image with low quality according to the user's image selection type. You can do

* Frame size handling-Parse the frameset to find the frame containing the body (hereinafter referred to as the body frame) and process the body frame to optionally fill the entire screen size (Full size) or the original frame size It is handled by the browser so that it can be restored.

In order to handle the frame size, the part of the original frame size is included in the program source that goes down to the browser as a variable, and when the command to hide the frame is made, the body of the variable in the frame size occupies 100% of the screen. . The remaining frame size is set to 0%, so only the body frame is shown on the screen.

Frame hiding / showing is handled in a toggling manner, and a selection for toggling is included in a part of the screen to provide a switch function for viewing the body only or as a part of the whole composition.

* Pop-up Window Handling-If the user doesn't want to display the pop-up window, the popup window will not be created because the relevant part (the part that creates the window from the JavaScript program sourced in the browser) is commented out. .

Referring to the operation of the present invention in more detail as follows.

First, the user connects to the proxy server and records the settings on the personal settings page.

The settings are saved as cookies. At this time, the settings stored in the cookie include a frame, a popup, an image, and the like.

The user of the web browser 10 accesses the intelligent proxy server 20 and inputs a desired site through a portion for inputting a URL or a classified directory service function.

The proxy server 20 then retrieves the page input by the proxy function from the original source site 30 or finds the document from the cached content. At this time, when the desired document is imported from the original source site 30, the original document is transmitted to the original source site 30 by requesting a URL.

Such original documents may be in the following format:

<frameset>

<frame>

</ frameset>

<h1> subject </ h1>

<p> ----

<img src = "/ ... / ...">

Parsing and processing the original HTML secured here is as follows.

That is, it finds the syntax for opening a pop-up window of JavaScript, including a frame, an image, an object, an applet, and an embedded tag.

It either replaces the original tag or code part with an indication of the specified special syntax or marks the location.

The original HTML content up to that point is also encoded according to JavaScript's escape rules.

In addition, all the substitutions (such as the original tag content) are handled so that they can be assigned to JavaScript variables.

The document parsed and processed by the proxy server 20 is in the following format.

<script>

var html = "--------------------------"

variables

logics

</ script>

On the other hand, if caching is required, the web page is saved to a file.

The original web page is then processed and sent new HTML containing the data to the browser.

It also converts the HTML data in the code processed by the browser into an array of strings based on the specified syntax.

For every string array, it is created as an escaped HTML string sequentially based on the delimiters set in the cookie. It then unescapes and writes the web document from the processed string.

The document newly written in the web browser 10 is a new page including the processing required for the original web document.

If you use this feature, you can hide pop-up windows, hide gif images, hide all images, hide adult information, remove frames, and reset the screen size.

As such, the present invention improves the response speed when using a web page in an environment where network bandwidth is poor, and improves the efficiency and response time when using the web in an environment in which browsers such as PDAs / TVs are poor in expression.

Although the preferred embodiment of the present invention has been described above, the present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. Accordingly, the above description does not limit the scope of the invention as defined by the limitations of the following claims.

As described above, the method for setting and using a personal symbol of a web browser according to the present invention improves response speed by removing unnecessary objects in a web page, and provides an efficient screen configuration by controlling a frame structure in a small screen size environment. This becomes possible, and it becomes possible to compose a web page which can be controlled according to the user's setting.
