FR2779594A1 - Method for optimizing the access speed for an internet web site - Google Patents

Abstract

The method optimizes the speed access a web page. At the time a visitor makes an access request, a web page (i) is loaded by the internet navigator. This page (i) is integrated or attached a data solution, interpreted by the internet navigator, which effects an anticipated loading into cache memory (C) of the page (i+1). The page (i+1) is defined as the page which directly succeeds the page (E) displayed.

  Method for optimizing the speed of consultation of a website

Description

  Technical Field The present invention relates to a method for optimizing

  the speed of consultation of a website.

  State of the Prior Art General A website is a collection of linked computer pages

  between them by links called "hypertext links" and organ-

  established in a tree structure. The computer pages present

  texts, images and videos on the computer screen.

  A website can be consulted through the use of software

  viewer says internet browser.

  The website can be consulted either online on the Internet by making a remote request on the server computer

  hosting the website or offline for example on CD-

  Rom. In both cases, the browser loads in its memory-

  re hides and displays on the screen the requested website page

by the user.

  The page display is rarely immediate because the website page is successively loaded and displayed at

  from remote digital media. The display time

  Age of the page, which determines the speed of consultation of the website, is a function of the loading time of the digital data constituting the page (or pages). The speed of consultation of the website is therefore a function, on the one hand, of the connection bandwidth available on the Internet at the time of the loading of a page of the website and, on the other hand, the intrinsic performance of the website. user's computer. -2 The invention relates to websites consulted online on the Internet or offline, whether on CD-Rom or any

  other digital recording media.

  Devices of the prior art In the devices of the prior art so that the speed of consultation of the website is optimized: On the server side, use is made of servers

  "proxy", which are large capacity storage units

  intermediate cities between the user and the server

  hosting the website. This process requires enormous capacities.

storage cities.

  On the user side, the website visitor can do the

  quisition of dedicated software that he installs on his computer

  nator. These dedicated software then add an acceleration function to the browser's cache. They function as a proxy server for an individual computer and automatically copy all pages to the visitor's disk

  linked to those being consulted.

  Among the devices of the prior art, the software referenced

  mentioned at the end of the description is one of the devices

  putting to optimize the speed of consultation of the website.

  This process requires the installation of software on the computer.

nator of each visitor.

  None of the devices of the prior art mentions a process on the website side. The present invention consists of a

  intrinsic process to the website with the aim of optimizing

  ser the speed of consultation of the website by taking advantage

browser cache memory.

- 3 - Statement of the invention

  The present invention relates to a method for optimizing

  ser the speed of consultation of a website.

  The website is consulted page by page. At the moment the visitor requests it, a page (i)

  of the website is loaded by the Internet browser.

  Attached to this page (i) in reading is an IT solution which performs an early loading in cache memory of the page browser (i + 1). The page (i + l) is defined as the page which succeeds directly in reading at

the page (i) displayed.

  The process takes advantage of the time taken by the visitor to read the page (i) in order to make the best use of the bandwidth of the connection and to carry out the anticipated loading in

page cache memory (i + l).

  When the visitor requests to read the next page (i + l), the page (i + 1) is immediately displayed because this page (i + 1) will have been "pre" loaded in the browser's cache when reading the previous page (i) thanks to an attached IT solution. The page (i + l) contains the IT solution for loading the page (i + 2), each page being programmed to "preload" the following pages. If page (i) leads to more than one

  pages, these are the several pages that will be "pre" loaded

  aged. The process thus optimizes the speed of consultation of a website by taking advantage, in a relevant way, of the time

  of the visitor's reading which offers the possibility of

  follow the loading of pages by the browser.

  - 4 - This process is characterized in that, when the user

  consult the website, the pages are themselves program-

  mées to optimize the speed of consultation of the site whether online (website on remote server) or offline (website recorded on any digital medium such

than CD-Rom, hard drive).

  The problem of consulting a website is that the speed of display of the page in reading is related to the bandwidth of the connection or the speed of access to the

  website storage medium (e.g. CD-Rom, hard drive).

  As a result, the display of the page in reading of the website is rarely immediate. The method of the invention overcomes this drawback by desynchronizing in two

  separate times loading and display of pages.

  Figure 1/1 schematically illustrates the tree structure of a

  website, in which the information process is implemented

  vention. In this figure are presented the pages (i, i + l, i + 2,

  i + 3 and i '+ l, i' + 2, i '+ 3) of the website.

  The cache memory of the Internet browser is designated by the

letter "C".

  The letter "E" indicates the computer screen. At the letter E

  is annexed the page which is viewed by the visitor.

  The arrow system indicates the page cache loading operation. Example: - If the visitor sees the page (i) on the screen, the page (i) automatically orders the loading in cache memory

"C" of pages (i + l) and (i '+ l).

  - If the visitor views the page (i + 2) on the screen, the page (i + 2) automatically commands loading into memory

cache "C" of the page (i + 3).

  tick attached to page (i) being read.

  The IT solution can be written in a programming language (example: Javascript or Java) interpreted

by Internet browsers.

  The Javascript programming lines below defined-

  feels an IT solution for the process integrated on page (i): <HTML><HEAD> <TITLE> page (i) </TITLE> </HEAD>

<BODY>

HTML layout code (i)

</BODY>

  <SCRIPT LANGUAGE = "JavaScript"> <! - function precache () {precachel = new Image precachel.src = "imga.jpg" precache2 = new Image precache2.src = "imgb.jpg" precache3 = new Image precache3.src = "imgc.gif" etc ...} precache () // ->

</SCRIPT>

</HTML>

  The IT solution is placed at the end of the HTML code of

  the web page (i) to run only at the end of the affi-

  layout chage (i). The IT solution cor-

  responds to the programming of a function here called "precache" which is initialized and then executed "precache ()" The computer files loaded imga.jpg, imgb.jpg,

  imgc.gif etc ... are constitutive of the page (i + l).

Claims (5)

Claims   1. Method intended to optimize the speed of consultation of a website comprising the following principle: At the moment when the visitor requests it, a page (i) of the website is loaded by the Internet browser. On this page (i) in reading is integrated (or attached) a   IT solution interpreted by the Internet browser which performs an early loading in the browser's cache memory of the page (i + l). The page (i + 1) is defined as the page which directly succeeds in reading the page (i) displayed.   2. Method according to claim 1, characterized in that during the reading time of the visitor to the page (i), the page (i + l) is loaded automatically into the memory browser cache.   3. Method according to claim 1, characterized in that during the reading time of the visitor to the page (i), the Internet browser remains active while loading its cache memory.   4. Method according to claims 1, 2 and 3, characterized   in that if the page (i) comes to lead to several pages (i + l, i '+ l, i' '+ l), it is these several pages which will be "pre" loaded.   5. Method according to claims 1, 2, 3 and 4, character-   risky in that the IT solution is functional online (website on a remote server) and offline (website recorded on any digital medium such as CD-Rom, Hard disk).
