Method of reducing time to download a web page

Abstract

A method for reducing time to download a web page includes storing a web page and its expiry time, and checking if the web page is expired according to its expiry time after a client delivers a request to a server to download the web page. If the web page is not expired, the server will directly transmit the web page. If the web page is expired, the server will execute programs again to update the web page, and then transmit the updated web page.

Description

technical field [0001] The invention relates to a method for shortening the time for downloading a webpage file, in particular to a method for shortening the downloading time for a webpage with a large number of program operations and a large amount of database data to be read. Background technique [0002] With the advent of the information age, the amount of data has increased rapidly. Early web pages were composed of content stated in hypertext markup language (HTML). However, such webpage content relies on the word-for-word design of webpage engineers, and is not a dynamically rendered page. [0003] But in today's era when e-commerce is prevalent, webpages are no longer just beautifully designed frames, not just fixed pictures and texts. People can operate more on webpages, and the content requirements of webpages have become more complicated. , various dynamic web programming languages, such as Hypertext Processor (PerlHypertext Processor, php), Dynamic Server Pages (...

Problems solved by technology

[0002] With the advent of the information age, the amount of data has increased rapidly. Early web pages were composed of content stated in hypertext markup language (HTML). However, the content of such a web page depends on the word-by-word design of web engineers, and is not a dynamically rendered page

[0003] But in today's era when e-commerce is prevalent, webpages are no longer just beautifully designed frames, not just fixed pictures and texts. People can operate more on webpages, and the content requirements of webpages have become more complicated. , various dynamic web programming languages, such as Hypertext Processor (PerlHypertext Processor, php), Dynamic Server Pages (Active Server Pages, asp), Java Server Pages (Java Server Pages, jsp)... etc. began to compete in different Among the characteristics of these languages ​​with the same purpose in commercial web pages, there is one most worth mentioning: this type of program is completed by the programming language actively controlled and executed by the server, and the more important work of these programs is , is to connect to the database, obtain various sorted and organized data, present them on the web page, and provide them for browsing by people who need them; however, everyone who is familiar with web technology knows that when a client requests the server to read For a certain webpage file, the server executes the webpage program first, and then transmits the execution result and the webpage file to the client. Most of the content of the webpage program needs to connect to the database to read data, but the time required for the database connection is very long, and The load capacity of the database is limited. When there are many clients, it is likely to cause too many database connections and excessive load.

[0004] As mentioned above, in order to design dynamic webpages, it is hoped to reduce the workload of the server when processing webpages. Therefore, VIA Electronics Co., Ltd. proposed a method for reducing the workload of the server when processing webpage files in Taiwan Patent Publication No. 00594500. The method is to record the server-side instructions and client-side instructions in the specific webpage file respectively in the corresponding storage locations in the specific webpage file to form a specific index data, which can make the server directly execute the server-side instructions, respectively. The result after sending the client command and the server command; that is, when the client sends a read request, the server still needs to spend time and resources to execute the server command, connect and read the database content; When the number of clients requesting to read files reaches a certain number, the load on the database connection will become very heavy, which will affect the speed of downloading webpage files
