Abstract

PURPOSE: A method for accelerating of a signaling speed between a web-browser and a web-server, and a computer-readable recording medium including a program for executing the same method are provided to improve a page load speed by preventing the occurrence of a network traffic. CONSTITUTION: A request command for web contents is transmitted to a web acceleration client(S401), and the web acceleration client investigates whether or not the URL information including the request command is a shape management target URL corresponding to a shape management information rule(S402). It is judged whether or not a cached-CMI-time exists at a cached point when web contents are cached to a client(S404). The shape management data information for the cached point is loaded(S405), and a fresh-CMI-time is compared with the loaded shaped management data information(S406).

Description

Method for Accelerating of Signaling Speed between Web-browser and Web-server and Computer-Readable Recording Medium Where Program Executing the Web Browser and Web Server Same Method}

The present invention relates to a web communication acceleration method for improving a communication speed and reducing a load of a web server during a communication process between a web browser and a web server.

With the advent of the world wide web, millions of users around the world can easily download web pages, including text, graphics, and video, that reside on a web server through a personal computer's web browser.

However, the web server has a limitation in the concurrent processing capacity. In the web server, when a large amount of page requests are crowded at once, the server capacity is overloaded, resulting in an unresponsive or wait response request. Within a computer network, network congestion and limited bandwidth can delay data transmission.

This is especially true if the majority of users are flocking to meet the deadlines of banks and public institutions, and banks and public institutions are required to significantly increase the capacity of their web servers during periods when server capacity is expected to be overwhelmed. A lot of work is happening.

Previously, web cache function was added to web browser to solve this problem. In other words, when a web browser first connects to a web server and makes a request for data transmission of the web page, the web server transmits the data to the web browser, and the web browser stores the data of the web page in cache memory and finally modifies it. Record the Last-Modified Time and its capacity.

If the web browser subsequently connects to the same web server after the second time, the web browser does not unconditionally request the data of the web page, but together with the last-modified time stored in the cache memory to the web server. send. The web server determines whether the data of the web page in the web server has changed since the last-modified time, and if not, gives a "304 Not Modified" response and the web browser receives the cache. It reads data of related web page from memory and uses.

In other words, the HTTP protocol itself includes the date information (IF-Modified-Since) of the client's cached web content in the HTTP Request Header to reduce network traffic, and the server has last-modified the web content requested. ) If it compares the date and the date sent by the client, and sends the response "304 Not Modified", it does not download unnecessary web contents.

However, since the HTTP protocol itself has to check every URL unit to know if the web content has changed, the load that the web server has to process the HTTP request does not decrease. In other words, the caching function of HTTP protocol reduces network traffic load, but it does not reduce the HTTP request load (the number of transactions that the web server must handle) coming into the web server.

In addition, the conventional web acceleration method is to reduce the amount of traffic through the compression of the web content, most of the web acceleration effect is seen. However, even in this case, the number of HTTP requests coming into the web server is not reduced. The present invention differs from existing methods in that it reduces the number of HTTP requests.

According to the present invention, when a web browser requests web content through an HTTP request through configuration management, it is obvious that a "304 Not Modified" response situation will occur from the server, and the cache is stored in the client web content repository without sending the corresponding HTTP request to the server. By loading loaded web content directly, the client has no time to send or receive a request to the server, resulting in no network traffic, resulting in a noticeably faster page load, and a server that doesn't expect a 304 response. By reducing the number of requests, you can reduce the CPU load on the web server.

The present invention to solve the above problems,

A first step of receiving new shape management date information (Fresh-CMI-Time) through a specific URL of a web server and storing it in a memory; Receiving a request command for web content from a web browser; Determining whether the URL information included in the request command is a shape management object; And a fourth step performed when the URL information included in the request command is a shape management target, wherein the fourth step includes whether or not web content corresponding to the request command is cached in a web content store. If it is determined that it is not cached, the request command is transmitted to the web server, and if it is cached, shape management date information (Cached-CMI) at the time of being cached from a cache entry of the web content. Step 4-1 of obtaining a time) and comparing the cached-CMI-Time of the cached time point with the new shape-management date information (Fresh-CMI-Time). And, if the comparison value of the step 4-2 is the same, and the step 4-3 of transferring the path of the web content existing in the web content storage to the web browser, in the communication process of the web browser and the web server Communication Improve and provide a way to reduce the load on the Web server.

If the web content corresponding to the request command is not cached in the web content storage in the fourth step, the web corresponding to the request command from the web server after transmitting the request command to the web server. If the content is delivered, store it in a web content repository, create a cache entry in the web content repository, and add the new configuration management date information (Fresh-CMI-Time) of the first step to the cache entry. It may further include.

If receiving a response from the web server that the web content corresponding to the request command has not been modified, updating the new configuration management date information (Fresh-CMI-Time) of the first step in the cache entry; Can be.

In addition, the first step of receiving the new configuration management date information (Fresh-CMI-Time) via a specific URL of the web server and stores it in the memory; Receiving a request command for web content from a web browser; Determining whether the URL information included in the request command is a shape management object; And a fourth step performed when the URL information included in the request command is a shape management target, wherein the fourth step includes whether or not web content corresponding to the request command is cached in a web content store. If it is determined that it is not cached, the request command is transmitted to the web server, and if it is cached, shape management date information (Cached-CMI-) at the time of being cached from a cache entry of the web content. Step 4-1 of importing time), and step 4-2 of comparing the cached-CMI-Time (Cached-CMI-Time) of the cached time point with the new Configuration-Managed Date information (Fresh-CMI-Time); And a fourth method of transmitting the request command to the web server after adding the last modification date of the web content of the cache entry to the request command if the values compared in the step 4-2 are not the same. Poe -3-1 steps Which is improved communication speed in the communication process of a Web browser and a Web server and provides a way to reduce the load on the Web server.

In addition, the first step of receiving the new configuration management date information (Fresh-CMI-Time) via a specific URL of the web server and stores it in the memory; Receiving a request command for web content from a web browser; Determining whether the URL information included in the request command is a shape management object; And a fourth step performed when the URL information included in the request command is a shape management target, wherein the fourth step includes whether or not web content corresponding to the request command is cached in a web content store. If it is determined that it is not cached, the request command is transmitted to the web server, and if it is cached, shape management date information (Cached-CMI) at the time of being cached from a cache entry of the web content. Step 4-1 of determining whether there is a Time) and configuration management date information (Cached-CMI-Time) at the time when the cache entry was cached in the Cache Entry in step 4-1 does not exist. And a step 4-2-1 of adding the last modification date of the web content of the cache entry to the request command, and then transmitting the request command to the web server. and Increase the transmission rate from and includes a method of reducing the load on the Web server.

In this case, when the web content corresponding to the request command is received from the web server, the web content storage is stored in the web content storage, a cache entry is created in the web content storage, and the new shape management date of the first step is stored in the cache entry. The method may further include adding information (Fresh-CMI-Time).

If receiving a response from the web server that the web content corresponding to the request command has not been modified, updating the new configuration management date information (Fresh-CMI-Time) of the first step in the cache entry; Can be.

Then, a computer readable recording medium having recorded thereon a program for performing the above method is provided.

According to the present invention, since the file cached by the configuration management information file is utilized, a request expected to receive a "304 Not Modified" response is not performed to the web server. Therefore, since there is no time for the client to send and receive requests to the server, network traffic does not occur, so the page load speed is noticeably faster. For the server, the request that is expected to be 304 response does not come in. It can reduce the CPU load.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view of the configuration of the present invention. 2 is a block diagram of a client component of the present invention. 6 is an exemplary diagram of a shape management file for web content according to an embodiment of the present invention.

The components of the present invention consist of a web acceleration client module 10 plugged into a web browser, a client web content repository 14, and a configuration management file existing on the web server side. Here, the web acceleration client module corresponds to a program for performing the steps according to the present invention, and performs a function of intelligently managing a web request after downloading a configuration management information file posted on a web server.

The client web content store 14 refers to a storage device such as a memory or a hard disk. Usually it means a temporary internet file repository that is set by default in your web browser.

The configuration management file is generated on the web server side and is a file in which configuration management information (Configuration Management Information) and final web content modification information (file name, date information, etc.) are recorded as shown in FIG. The last updated date of the image file and the flash file constituting the web page subject to configuration management is displayed in Korean time or GMT.

The web acceleration client module 10 having received the information on the specific URL requested by the web browser 12 requests the configuration management file for the specific URL from the web server and transmits the configuration management file to the client.

3 is a flow chart of a method for reducing the load of a web server according to an embodiment of the present invention. 4 and 5 are continuation of the flowchart of FIG. 3.

In FIG. 3, the loading process of the web acceleration client is displayed in order. The web acceleration client downloads the configuration management file containing the configuration management information from the web server through a specific URL of the web server (S301). As mentioned above, the configuration management file is generated in the web server. The web acceleration client stores new configuration management date information (Fresh-CMI-Time) for each web content URL in memory. (S302) The new configuration management date information (Fresh-CMI-Time) for each web content URL is received from a server. It means CMI Time, and can be date information recorded in the configuration management file.

This must be distinguished from the cached configuration management date information (Cached-CMI-Time). The shape management date information (Cached-CMI-Time) at the cached time point refers to the CMI time stored in the cache entry. When the new configuration management date information (Fresh-CMI-Time) is stored in the cache entry, it becomes the configuration management date information (Cached-CMI-Time) at the cached time.

The web acceleration client prepares to filter the request command of the web browser (S303). The request command may be an HTTP request.

These steps prepare the web acceleration client for loading.

4 illustrates a process of a web acceleration client receiving a web content request from a web browser in order.

First, a request command for web content is generated from a web browser. The request command is transmitted to the web acceleration client (S401). The web acceleration client first checks whether the URL information included in the request command corresponds to the configuration management target URL corresponding to the rule of the configuration management information received from the web server. (S402) Not all web pages are targeted for URLs that are subject to configuration management, but the target is a web server that purchases and installs a web acceleration client. It can be a bank or a public institution (home taxi). In addition, not all the homepages of the banks and public institutions are subject to shape management. Among them, it may be desirable to target a web page with a heavy load and a web page that is not frequently updated.

If it is determined in step S402 that the object is not the shape management target, the request is forwarded to the default HTTP handler embedded in the web browser, and then the processing for the corresponding request is terminated (S409).

If it is the configuration management target, the web acceleration client checks whether the web content corresponding to the request command generated from the web browser is cached in the client web content storage (S403).

If cached, the cache entry of the web content is taken to determine whether the shape management date information (Cached-CMI-Time) at the time when the web content is cached in the client exists (S404), and if so, it is loaded. 7 is an exemplary diagram of a cache entry configuration according to an embodiment of the present invention. Among the items, CMI Time may correspond to this.

Load the configuration management date information (Cached-CMI-Time) of the cached time point (S405) and compares it with the new configuration management date information (Fresh-CMI-Time) stored in step S302. (S406) )

If the date information is the same, it is determined that the corresponding web content of the web server is the same as that currently stored in the client's web content store. Therefore, it does not execute a separate request command to the web server. The web acceleration client reports the path of the web content existing in the web content repository to the web browser (S407), and the web browser loads or outputs the web content on the screen based on this (S408).

The service administrator of the web server does not update the web content every hour, nor does it modify all the web content, so if you know when the administrator last modified the web content, you will see a response of "304 Not Modified". It can be predicted in advance. Web content that is sure to receive a response of "304 Not Modified" is loaded when the web content stored in the PC is quickly displayed on the PC, and the request does not come from the Web server. There is an advantage that does not occur.

In general, considering that the number of requests that an instance can process at the same time based on Apache web server is about 500 to 1000 per second, the load on the server can be reduced if the request itself does not occur.

The difference from the existing cache function is that the cache function must send a request, and when a response of "304 Not Modified" is received, the content is not downloaded from the web server, whereas the web acceleration method according to the present invention is " The request itself is not sent to the web server in advance until a response of "304 Not Modified" is received.

If the web content is not cached in step S403, the web acceleration client transmits a request command to the web server. (S501) And determines whether a "200 OK" response comes from the web server (S502) "200 OK" "Response means that the web content is different from what was received before, and that the web content must be downloaded. In this case, the new configuration management date information recorded in the memory in step S302, in addition to the new cache entry in the client web content repository and the information basically written by the web browser to the cache entry (Last-Modified Time, Content-Length, MIC, etc.). (Fresh-CMI-Time) is additionally recorded. (S503) This setting is made in case there is a request request from a web browser for the same web content.

If a response of "304 Not Modified" comes from the web server (S504), it means that the web content exists in the client PC, and the web content in the web server is not newly updated. Therefore, the web content does not need to be downloaded separately from the web server, but the new configuration management date information (Fresh-CMI-Time) recorded in the memory in step S302 is updated in the cache entry for the defect management.

Thereafter, the web acceleration client reports the path of the web content existing in the web content repository to the web browser (S407), and the web browser loads or outputs the web content on the screen based on this (S408).

If the configuration management date information (Cached-CMI-Time) of the cached time point at step S404 does not exist, the web acceleration client transmits a request command to the web server (S501). It is determined whether to come (S502), "200 OK" response means that the web content is different from the previous received means that the web content should be downloaded. In this case, the new configuration management date information recorded in the memory in step S302, in addition to the new cache entry in the client web content repository and the information basically written by the web browser to the cache entry (Last-Modified Time, Content-Length, MIC, etc.). (Fresh-CMI-Time) is additionally recorded. (S503) This setting is made in case there is a request request from a web browser for the same web content.

If a response of "304 Not Modified" comes from the web server (S504), it means that the web content exists in the client PC, and the web content in the web server is not newly updated. Therefore, the web content does not need to be downloaded separately from the web server, but the new configuration management date information (Fresh-CMI-Time) recorded in the memory in step S302 is updated in the cache entry for the defect management.

Thereafter, the web acceleration client reports the path of the web content existing in the web content repository to the web browser (S407), and the web browser loads or outputs the web content on the screen based on this (S408).

When the configuration management date information (Cached-CMI-Time) cached at step S406 and the value of the new configuration management date information (Fresh-CMI-Time) stored at step S302 are different, the web content of the web server is recently updated. It means that it has been updated. Therefore, there is a need to update the web content of the client web content repository.

Accordingly, the web acceleration client sends a request command to the web server (S501) and determines whether a "200 OK" response is coming from the web server (S502). The "200 OK" response is different from that previously received by the web content. This means that web content must be downloaded. In this case, the new configuration management date information recorded in the memory in step S302, in addition to the new cache entry in the client web content repository and the information basically written by the web browser to the cache entry (Last-Modified Time, Content-Length, MIC, etc.). (Fresh-CMI-Time) is additionally recorded. (S503) This setting is made in case there is a request request from a web browser for the same web content.

If a response of "304 Not Modified" comes from the web server (S504), it means that the web content exists in the client PC, and the web content in the web server is not newly updated. Therefore, the web content does not need to be downloaded separately from the web server, but the new configuration management date information (Fresh-CMI-Time) recorded in the memory in step S302 is updated in the cache entry for the defect management.

Thereafter, the web acceleration client reports the path of the web content existing in the web content repository to the web browser (S407), and the web browser loads or outputs the web content on the screen based on this (S408).

The present invention is not limited to the scope of the embodiments by the above embodiments, all having the technical spirit of the present invention can be seen to fall within the scope of the present invention, the present invention is the scope of the claims by the claims Note that is determined.
