Device and method for accelerating display of web page of browser

Abstract

The invention discloses a device for accelerating display of a web page of a browser. The device comprises a proxy service end, a proxy client and a cache manager. The method for accelerating the display of the web page of the browser comprises the following steps: transmitting an IE request packet to the proxy client through the proxy service end by the browser; analyzing whether a web page corresponding to link information exists in cache or not by the proxy client; if the web page exists in the cache, displaying the page via a remote server; if the web page does not exist in the cache, determining the web page is failed or not, if the web page is failed, displaying the page via the remote server; if the web page is not failed, transmitting the web page to an updated IE response packet,and adding the link of the web page into an updated queue managed by cache at the same time; further analyzing each page element in the web page; and transmitting an updated IE request packet for thepage element which is not a static file. The device and the method adopt the method of separating display and update, and simulate the remote server to transmit the IE response packet, thereby reducing data interaction between the browser and the remote server, and accelerating the display of the web page of the browser.

Description

technical field [0001] The invention relates to a device for browsing network information, in particular to a device for accelerating the display of browser web pages. The invention also relates to a method for speeding up displaying web pages of a browser. Background technique [0002] Using a browser to access the Internet is one of the most basic applications of computer network technology. At present, there are various types of browsers such as IE, firefox, NetScape, Opera, Maxthon, etc., but they are all affected by two factors: access speed and real-time performance. The access speed requires that the browser can respond to the user's URL request in the shortest time, and the real-time nature requires that the latest content is presented to the user every time. [0003] A very important part of a browser is caching. How to use the caching mechanism is an important indicator for evaluating the performance of a browser. The caching mechanism is to save the pages visit...

AI Technical Summary

Problems solved by technology

There are two extreme situations. One is that as long as there is something in the cache, it will no longer request the service, but directly extract the page in the cache and display it. This situation is the fastest but the real-time performance is the worst.

The second is to request the target page from the remote server regardless of whether the target page exists in the cache. This is the slowest speed, but the highest real-time performance

[0007] Chinese Invention Patent Publication CN101075236A (published on November 21, 2007) discloses a device and method for accelerating browser web page display, by predicting the links in the current page, pre-downloading the web pages of each link and saving them to the local cache, Thereby speeding up the browsing speed of the browser. Although the above technology separates the display and the update, when the browser displays the locally cached page every time, it still needs to establish communication with the remote server according to the conventional operation and receive the confirmation returned by the remote server. The page is the IE response packet 304 of the latest page, and the browser displays the locally cached page. This interactive process is sometimes very fast and sometimes very slow, and the speed is affected by comprehensive network factors.

And the update of the above technology is pre-downloaded according to all the links of each page, and the queue for downloading updates becomes very large, and many of them are not visited by users. Downloading many redundant web pages wastes bandwidth and cache space
