Abstract

FIELD: information technology.

SUBSTANCE: during first user access to a web page, a web server executes program code to generate html code which includes static part html code and dynamic part html code. The web server outputs the html code of the web page to user equipment. The web server detects dynamic parts in the html code and replaces said parts with JS to form composite code. The composite code is stored in a storage device. The JS contains instructions to obtain relevant dynamic part code from the web server. During repeated accessing of the web page by the user equipment, the web server outputs the composite code from the storage device to the user equipment. A browser in the user equipment displays said dynamic parts in corresponding fields of the already output static part of the web page.

EFFECT: enabling fast display of web pages to a user, which is achieved by using, in the web pages, dynamic parts which are processed on the user equipment.

Description

Technical field

This invention relates to the field of web technologies and, in particular, to the field of providing data via computer networks based on the World Wide Web, such as the Internet, Intranet, etc. The object of protection is the method of issuing web pages to user equipment, as well as corresponding thereto the way the system.

State of the art

One of the most important parameters of work on the World Wide Web is the time taken by the system to deliver web pages to the user's browser from the moment the user equipment sends a client request to the corresponding page to the web server on which this page is located. The shorter the specified time, the more successful and comfortable browsing and manipulation of web pages occurs.

According to the current level of technological development, thanks to the use of fiber optic and multiplexed communication lines, it was possible to provide an extremely high data transfer rate of, for example, tens of Tbit / s. As a result, the main limiting factor that increases the display time of a web page in the user's browser is not the speed of data transfer over the Internet channel, but the speed of processing the requested page on the web server that stores it, which is carried out to generate the code for this page and translate it into An appropriate format that is understandable to the software installed on the user's computer.

If the requested webpage is static, i.e. the information transmitted through it is always the same and does not depend on the time and viewing conditions, the server sends the code to the user's computer quickly, because in this case the server has to solve the simplest task - send the user a ready-made html file.

However, at the current level of the Internet, this situation is extremely rare, and given the further development of web technologies, it can generally be considered a thing of the past. The reason is that web pages hosted on servers, in the vast majority of cases, in addition to static parts, also contain dynamic parts, the processing of which takes a very substantial amount of time, hundreds or more times longer than the processing of static parts. By dynamic parts or dynamic content in this technical field, it is customary to understand the information posted on the site that is updated at least every few minutes, or information that may differ in terms of the request for different users. Examples of dynamic content include audio and video data, counters and stopwatch, polling and voting forms, animations, games, shopping carts and other dynamic objects that almost all modern websites abound in.

The management of sites containing dynamic-looking content is traditionally built using CMS-systems (content management system from the English. Content Management System). CMS-system is a computer program that provides site developers with convenient tools for storing and publishing text, graphic and other content of the site. Such systems facilitate the task of managing content for unskilled programming employees of companies and website owners.

One of the features of the CMS-system is that working with it does not require the installation of any additional software on the computer from which the site is being worked on. The CMS system itself is located on the provider's server, and the user just needs to have a normal browser in order to access the site and manage it. When editing / adding content to the site, the user operates with simple and understandable tools, without resorting to the html code or program code y. These tools include, in particular, administrative sections, modules, components with templates, etc.

The main tools for displaying information on the pages of the site created by the CMS-system are components with templates. The specified components are the program code responsible for the interaction of the CMS system and the information managed by the component. A component template is a kind of shell that is responsible for the form and method of outputting information managed by a component. Templates can be modified by changing the way and form of output.

Meanwhile, for the indicated simplification of working with web pages containing dynamic content, you have to pay extra load on the web server. In this case, the web server is forced to generate the html code of the page sent to the user from the program code of the CMS system. As a rule, php code is used as the code of the CMS system. Other examples of program code include perl, asp, jsp, etc. The server takes a lot of time to generate the final html-code of the page, since it has to convert all the dynamic parts of the page from the program code (for example, php-code) to html-code and correctly combine them with the html code of the static part. As a result, the page for the user opens with a significant delay, up to several seconds, which, of course, is unacceptable.

In the art, as part of the solution to the problem of delays when viewing pages, it was proposed to create a page cache during the first visit of this page by a user, followed by saving the cache in a special file on the server’s disk. In this case, the return of the web page to each user, starting from the second one, occurs quite quickly, by issuing its stored cache.

However, very often a website has to display only slightly modified pages for users. For example, to display one price on one and the same product page for one user and another for another, in particular, taking into account the discount due to that user. Both pages can be almost the same, the difference can be only one figure in the price.

In such a situation, according to the prior art, it is envisaged either to create several copies of virtually the same page, or to reprocess the page as a program script, i.e. re-create a dynamic page. However, both of these decisions have significant disadvantages. In the first case, numerous copies occupy a large place on the server’s disk, and working with the created files slows down the site as a whole. In the second, huge computing resources of the server are spent, and the page is still issued to the user with a delay.

A more effective means of the prior art for accelerating the delivery of web pages to user equipment is Full Page Cache technology from Magento Enterprise, which can be considered as the closest analogue of the present invention. This technology is applicable only to work with web pages whose code contains labels indicating the presence of all dynamic parts in a web page. When a user first accesses such a web page, the Full Page Cache program module executes the page in dynamic mode, sends the user its code and saves the page cache in the server’s storage device with the removal of information from its dynamic zones. The second time the user accesses this page, the server executes the code of the dynamic parts, glues the cache of the page, taken from the storage device, with the generated code of the dynamic parts and gives the page to the user.

Full Page Cache technology speeds up the process of delivering pages to the user to some extent, but it also has a number of disadvantages. For example, the output of the code of the requested page to the user equipment cannot begin until the gluing of the page cache with the generated code of the dynamic parts is completed, which eliminates the possibility of taking advantage of the background load and increases the peak load on the server. As a result, the ability to accelerate the downloading of pages to user equipment is not fully realized. In addition, Full Page Cache technology has problems with periodic cache obsolescence and the inability to cache pages when they are modified by the user.

Taking into account the foregoing, the applicant formulates the objective of the present invention as the development of technical means for issuing web pages to a user that would be free from the disadvantages of the prior art, i.e. It would combine the advantages of quickly delivering pages to the user with the flexibility of displaying information depending on the time and on various conditions of the page request, for example, access rights and user status.

Disclosure of invention

The object of the present invention is solved by developing a method for generating and displaying web pages to a user and a system corresponding to this method.

The proposed method of issuing web pages containing at least one dynamic part to user equipment corresponding to the first aspect of the present invention includes the following steps:

- the first time a user equipment accesses a web page hosted on a web server:

- execution by the web server of the program code of the web page, including the dynamic parts available on it, with the formation of the html code of the web page, including the html code of the static part and the html code of the dynamic parts;

the web server issuing the html code of the web page to the user equipment for displaying the web page by a browser installed on the user equipment;

- detection by the web server in the html code of the web page obtained at the stage of generating the html code, the code related to the dynamic parts;

- replacement by the web server in the html code of the web page of the specified code related to the dynamic parts with a JS script containing a prescription for receiving the actual code of these dynamic parts from the web server, with the formation of the composite code and saving this composite code in a memory device

- at the second and subsequent calls of the user equipment to the web page:

- issuance by the web server of the user equipment to the composite code stored in the storage device for display by the browser installed on the user equipment, the static part of the web page;

- the web server receives from the browser a request for up-to-date data for the dynamic parts sent by the browser by following the instruction contained in the composite code JS script;

- execution by the web server of the program code of the dynamic parts to obtain the current html-code corresponding to these parts;

- sending by the web server the actual html code of the dynamic parts to the user equipment for display by the browser installed on the user equipment, the indicated dynamic parts in the corresponding fields of the already displayed static part of the web page, according to the generated html code of these dynamic parts.

According to one embodiment of the invention, the step of detecting by the web server in the html code of the web page the code related to the dynamic parts is carried out using the instructions in the code of the web page marking these parts of the page as dynamic.

According to another embodiment of the invention, before the step of issuing the composite code to the user equipment, the web server checks for the presence of this composite code in the storage device, and if there is no composite code, the web server considers this user equipment access to the web page as the first and proceeds to the steps, relating to the first appeal.

In a preferred case, the web server at the stage of issuing to the user equipment a composite code stored in the storage device, additionally sends to the user equipment an object code intended for temporarily replacing the dynamic parts of the web page.

In accordance with another embodiment of the invention, the method further comprises the step of calculating the checksum of the composite code by the web server, carried out after the step of generating the first time the user equipment accesses the web page, as well as the following steps performed after the step of sending the actual html by the web server code of dynamic parts for user equipment:

generation by the web server of the updated html code of the web page including the actual html code of the static part and the specified current html code of the dynamic parts;

- replacement by the web server in the updated html code of the web page of the specified code related to the dynamic parts with a JS script containing a prescription for receiving the actual code of these dynamic parts from the web server, with the formation of the updated composite code;

- calculating by the web server the checksum of the updated composite code and reconciling the sum of the updated composite code with the previous sum of the composite code and, if the amounts do not match, then the server stores the updated composite code in the storage device for future use.

According to another embodiment of the invention, if the sum of the updated composite code and the previous sum of the composite code do not match, the web server issues the updated html code of the web page to the user equipment for displaying the updated web page by the browser installed on the user equipment.

In a preferred case, the method further comprises the step of re-saving the previous composite code with assigning a new name to it.

Alternatively, the method further comprises the step of a web server simulating a user’s first access to a web page.

The proposed system for issuing web pages containing at least one dynamic part to user equipment in accordance with the second aspect of the present invention includes a web server with web pages located thereon and a storage device, the web server being configured to:

- upon the first access of the user equipment to the web page, perform the following actions:

- execution, upon request from the browser, of the program code of the dynamic parts with the receipt of the current html-code corresponding to these parts;

- sending the actual html code of the dynamic parts to the user’s equipment for display by the browser installed on the user’s equipment in the corresponding fields of the already displayed static part of the web page, according to the generated html code of these dynamic parts.

According to one embodiment of the invention, the web server is also configured to detect in the html code of the web page the code relating to the dynamic parts using the directions in the web page code marking these parts of the page as dynamic.

According to another embodiment of the invention, the web server is also configured to check, before the step of issuing the composite code to the user equipment, the presence of this composite code in the storage device, and if there is no composite code, the web server considers this user equipment access to the web page as the first .

In a preferred case, the web server is also configured to, during the issuance to the user equipment of the composite code stored in the storage device, send to the user equipment an additional object code for temporarily replacing the dynamic parts of the web page.

In accordance with another embodiment of the invention, the web server is also capable of calculating the checksum of the composite code after the stage of its generation when the user equipment first accesses the web page, as well as the ability to perform the following actions after the web server sends the actual html code of dynamic parts for user equipment:

generating an updated html-code of the web page including the actual html-code of the static part and the specified actual html-code of the dynamic parts;

- replacement in the updated html code of the web page of the specified code related to the dynamic parts with a JS script containing an instruction to receive the actual code of these dynamic parts from the web server, with the formation of the updated composite code;

- calculating the checksum of the updated composite code and reconciling the sum of the updated composite code with the previous sum of the composite code and, if the amounts do not match, then saving the updated composite code in the storage device for future use.

According to another embodiment of the invention, the web server is also configured to provide updated html code of the web page to the user equipment for displaying the updated web page by a browser installed on the user equipment, if the sum of the updated composite code and the previous sum of the composite code do not match.

In a preferred case, the web server is also configured to resave the previous composite code with a new name.

Alternatively, the web server is also configured to simulate a user’s first access to a web page.

Composite code in this application is understood to mean code containing the code of the static part of the web page and a special JS-script (script in JavaScript) containing a prescription for the user equipment to receive from the web server the actual code of all the dynamic parts included in this web page .

A brief description of the graphic materials

The invention is further disclosed in more detail by way of example of preferred embodiments thereof described with reference to the attached graphic materials, of which:

- figure 1 depicts a block diagram of the inventive system for issuing web pages to user equipment and schematically illustrates the operation of this system;

- figure 2 depicts a screenshot of a web page containing static and dynamic parts;

- figure 4 depicts a table reflecting the time of delivery to the user of the components shown in figure 2 of the page using the technology proposed in the present invention.

The implementation of the invention

A block diagram of the inventive system is shown in the right part of figure 1 circled by a dashed line. As follows from this figure, the system 1 for issuing web pages to user equipment 50, in particular to a stationary computer, laptop, smartphone, tablet, etc., contains a web server 10 with web pages 100 and a storage device 15 In special cases, system 1 may also include separate transceivers, switches, routers, consoles, power supplies, controllers, disk arrays, etc. However, we note that it is generally accepted in the art that a standard web server contains Functions of the above devices, hardware implemented thereon and / or software. In some embodiments of the invention, the web server 10 may include a storage device 15 (memory).

If you define it, web server 10 is a software and hardware complex accessible to the user via the Internet and configured to receive http-requests from users, usually from web browsers, and give them http-answers, usually together with an html page, image, file, media stream or other data. As specific examples of web server 10, Apache, US, Cherokee, and Resin http servers based on Linux, BSD, Mac OS, Microsoft Windows, Novell NetWare, BeOS operating systems can be named. A non-exhaustive list of features on a standard web server includes the following:

- Receiving requests from web browsers using the HTTP standard protocol using TCP / IP network protocols;

- Performing searches and sending files with hypertext or any documents to the browser via HTTP;

- Service and processing of requests, such as: mailto: ..., FTP, Telnet, etc .;

- Launching applications on a web server with subsequent transfer and return of processing parameters through the standard CGI interface;

- Work and maintenance of navigation image maps (Image map);

- Download Java applications;

- Authorization of users and their authentication;

- Maintaining a registration log of user requests to various resources;

- Automated operation of web pages;

- Support for pages that are generated dynamically;

- Support for HTTPS protocol for secure connections with clients.

The storage device 15 used in the system 1 is intended for recording and storing data used by the web server 10, in particular, composite html pages, dynamic and static parts of html pages, content necessary for filling html pages, supporting information, etc. As the storage device 15 can be used the hard drive of the web server, the RAM of this web server or the memory of other computers located on the Internet, and can also be used databases, software products such as Memc ache etc.

According to the principles of the present invention, the web server 10 included in the proposed system for issuing web pages to user equipment is configured to perform the following actions:

- when the user equipment first accesses the web page 100, perform the following actions:

- execution of the program code of the web page 100, including all the dynamic parts 101, 102, 103 present on it, with the formation of the html code of the web page 100, including the html code of the static part and the html code of the dynamic parts 101, 102, 103;

- issuing the html code of the web page 100 to the user equipment for displaying this web page 100 by a browser installed on the user equipment;

- detection in the html code of the web page 100, obtained at the stage of generating the html code, the code related to the dynamic parts 101,102, 103;

- replacement in the html code of the web page 100 of the specified code relating to the dynamic parts 101, 102, 103, with a JS script containing a prescription for receiving the actual code of these dynamic parts 101, 102, 103 from the web server 10, with the formation composite code 110 and storing this composite code 110 in memory 15;

- during the second and subsequent calls of the user equipment to the web page 100 to perform the following actions:

- issuing to the user equipment a composite code 110, stored in the storage device 15, for display by the browser installed on the user equipment, the static part of this web page 100;

- receiving from the browser a request for relevant data for the dynamic parts 101, 102, 103 sent by the browser by following the instruction contained in the JS script of composite code 110;

- execution, upon request from the browser, of the program code of the dynamic parts 101, 102, 103 to obtain the actual html code corresponding to these parts 101, 102, 103;

- sending the actual html code of the dynamic parts 101, 102, 103 to the user’s equipment for display by the browser installed on the user’s equipment, in the corresponding fields of the already displayed static part of the web page 100, according to the generated html code of these dynamic parts 101, 102,103 .

Due to such a configuration of the web server, the inventive system and method allows downloading web pages to user equipment, firstly, faster than when using means of the prior art, and secondly, more smoothly and with less load on the server. The static part of the page is issued to the user almost instantly, whereby the user can almost immediately start viewing the page. Soon, the user will also see the dynamic parts of the page sequentially and in the background. The process of page output proceeds smoothly and evenly, without overloading the equipment used.

These and other advantages of the invention are easier to understand by referring to FIGS. 2-4, illustrating a specific example of loading a web page containing dynamic parts.

Figure 2 shows a screenshot (i.e., screenshot) of a web page 100 containing static and dynamic parts. As you can see from the above example, the page shown refers to an online clothing store. Three dynamic parts 101, 102, 103 are provided on this page, each of which is highlighted by a rectangular frame.

Part 101 denotes a shopping cart; part 102 - telephone and opening hours of the delivery point; part 103 - the price. These parts may vary depending on the conditions and time of requesting page 100. For example, the price, telephone and working conditions corresponding to parts 102 and 103 may vary depending on the status of the client. In particular, wholesale customers and customers with the status of a "golden" customer can work at one price and be served at one business hours, while other customers will be served at another time and at different prices. The content of the part 101 relating to the user's basket depends on the price of the goods and on the number of units of goods ordered by the user.

The rest of page 100 is static, i.e. is unchanged and does not depend on the conditions and time of the request.

The web pages 100 stored on the web server 10 can be created using components with CMS system templates or other output modifiers. Alternatively, the code of the pages 100 can be written by a programmer in a low-level language, without using a CMS system or other similar software that manages the content of a web page.

Consider first what happens when a user tries to open this page 100 using prior art technology.

So, the user equipment browser sends a client request to the web server with the page address of 100. The web server, having received the request to page 100, takes steps to assemble the html code of this page, during which the following is performed:

- execution of the program code of the dynamic parts 101, 102, 103 related to the calculation of the basket for a given user, the output of the phone and the opening hours of the delivery point and the price of the goods. This stage can be carried out taking into account the status and access rights of the user, as well as other possible conditions for the formation of the page, and includes the selection of necessary data from databases related to customers, prices and assortment, filtering and sorting of these data and other actions necessary for generating the html code of parts 101, 102, 103. The php code is usually used as the program code, but perl, asp, jsp, etc. can also be used. The result of the execution of the program code of the dynamic parts is to obtain the html code a, corresponding to the indicated parts 101, 102, 103;

- the formation of the html code of the web page 100, including the html code of the static part and the html code of the dynamic parts 101, 102, 103 obtained in the previous step by executing their program code;

- the issuance of the generated html code of the web page 100 to the user equipment, followed by the display of the web page 100 by the user's browser.

As follows from figure 3, in this very simple example, the time elapsing from the moment the user accesses page 100, which contains only three dynamic parts 101, 102, 103, until it is displayed in the user's browser, is 483 ms, of which the actual display the page takes 26 ms, and the rest of the time it takes to assemble the final html code. All this time, the user sits in front of a blank screen of his equipment, waiting for the completion of the process of generating the page 100 code, as well as forwarding and displaying it.

Now consider the user receiving the same page 100 using the technology proposed in the present invention. As indicated above, the actions performed by the present invention to generate and issue a page upon first access to a user’s page are different from similar actions on subsequent user accesses to this page.

When the user equipment 50 first accesses the web page 100, the actions of the claimed system 1 essentially coincide with similar actions of the prior art system. The sequence of steps in this case is as follows. Browser of user equipment 50 sends a client request to web server 10 with page address 100. Web server 10, having received a request to page 100, takes steps to assemble the html code of this page, during which the following is performed:

- execution of the program code of the dynamic parts 101, 102, 103 related to the calculation of the basket for a given user, the output of the phone and the opening hours of the delivery point and the price of the goods. This stage can be carried out taking into account the status and access rights of the user, as well as other possible conditions for the formation of the page, and includes the selection of necessary data from databases related to customers, prices and assortment, filtering and sorting of these data and other actions necessary for generating the html code of parts 101, 102, 103. The php code is usually used as the program code, but perl, asp, jsp, etc. can also be used. The result of the execution of the program code of the dynamic parts is to obtain the html code a, corresponding to the indicated parts 101, 102, 103;

- generation of the html code of the web page 100, including the html code of the static part and the html code of the dynamic parts 101, 102, 103, obtained in the previous step by executing the program code of the dynamic parts 101, 102, 103 (this step in the general case may be combined with the previous step of the method of issuing web pages of the present invention);

- the issuance of the generated html code of the web page 100 to the equipment 50 of the user, followed by the display of the web page 100 by the user's browser.

The user's browser displays page 100 in the same 483 ms. However, for the web server 10, the processing steps for page 100 are not finished. He in the background performs two more steps, additional in comparison with the method of the prior art. The first of these stages is the detection in the html code of the web page 100, obtained at the stage of generating the html code, of the code related to the dynamic parts 101, 102, 103. The second additional step is to replace the specified code in the generated html code of the page relating to the dynamic parts 101, 102, 103, to a special JS-script containing a prescription for receiving the actual code of these dynamic parts 101, 102, 103 from the web server 10, with the formation of the composite code 110 as a result and saving this composite code 110 in its memory 15. After creating and saving the composite code 110, the actions of the proposed system 1 for generating and issuing the web page 100 to the first user are considered completed.

At the second and subsequent calls of the user to page 100, it doesn’t matter the same or new, using the same equipment or new, the actions of the system are as follows. The user browser sends a client request to the web server 10 with a page address of 100. The web server 10 sends the composite code 110 of the page 100 stored in the storage device 15 to the user equipment 50. Before sending, the web server 10 usually checks if the storage device 15 has file with code 110 corresponding to the page requested by the user. Such a check is advisable to exclude emergency situations. If there is no file, then the further execution of the method occurs, as indicated above in relation to the first user call. If there is a file, then it is sent to the user. Having received the code 110, the user's browser displays it to the user, and starting from this moment, the user can already see the requested page on his monitor, so far, however, only its static part, not filled with dynamic content.

Along with the procedure for displaying the static part of the page to the user, the browser, guided by the instruction contained in the JS script, sends a background request to the web server for the user to receive relevant data for the dynamic parts 101, 102, 103. After receiving the second request from the browser, the web the server 10 executes the program code of the dynamic parts 101, 102, 103, acting essentially in the same way as described in the corresponding part of this method relating to the first user access to the web page 100. The result of the step The completion of the program code of the dynamic parts is to obtain the html code corresponding to the indicated parts 101, 102, 103.

Further, the web server 10 sends the html-code of the dynamic parts 101, 102, 103 to the user's computer, containing up-to-date information about the user's basket, phone and the time of the delivery point and the price of the goods. The user browser immediately after receiving the html code of the dynamic parts displays these dynamic parts, for example, sequentially as they are received, for the user in the corresponding fields of the already displayed static part of the web page100.

If you turn to figure 4, you can see that during the second and subsequent calls to page 100, the user receives a saved page in just 15 ms, of which the actual display of the page takes 13 ms. Comparing this with 483 ms for the method of outputting pages known from the prior art, it is easy to understand that the present invention provides significant benefits in displaying even such simple pages, characterized by a relatively small number of dynamic parts. The following dynamic data comes to the user and is displayed for him after 500 ms, but since the human brain and organs of vision are not able to control such a transient change in visual information in different parts of the displayed web page, the user does not notice the process of updating the page, and he has the full impression of instantly loading the requested page, i.e. almost immediately after contacting the server for it. As a result, according to the technical solution proposed in the present invention, work with web pages occurs in a quick, comfortable mode, regardless of the amount of dynamic content on the requested page. In addition, due to the separation of the processes of outputting the static and dynamic parts of the web page to the user’s equipment, the web server loads more evenly, which favorably affects its service life.

In the general case, the step of detecting in the html code of the web page 100 the code related to the dynamic parts is performed by the web server 10 by analyzing its html code using the corresponding recognition software module. Moreover, according to a preferred embodiment of the invention, the detection of dynamic parts occurs according to special instructions placed in the code of the page by the developers of the site. For example, a CMS system installed on a web server analyzes the code of a web page while saving it to the server. If the CMS-system meets the program instructions set by the website developer, then the system replaces them with its own labels, by which it subsequently determines where to replace obsolete data with current ones. In this case, the stages of detecting dynamic parts and replacing them with a JS script proceed most quickly, which gives an additional gain in speed when displaying a web page.

According to another preferred embodiment of the invention, the web server 10, at the stage of issuing to the user equipment 50 a composite code 110 stored in the storage device 15, sends to the user equipment an additional object code for temporarily replacing the dynamic parts of the web page 101, 102, 103, i.e. e. until the moment when the actual information related to these dynamic parts comes from the server 10. This is done so that the user can determine by the appearance of the displayed static part that the page display process is not completed to the end. In accordance with some typical cases, at the place of the dynamic parts in a web page, for example, some information informing the user, in particular, the word “Download”, or information that was displayed during the last visit to the page, or may not be reflected at all, can be temporarily displayed . The code of the object displayed in the dynamic part before the JS script contacts the server, as a rule, depends on the preferences of the site developer. It can be adjusted programmatically when configuring component templates.

In a preferred case, the web server 10, when issuing web pages to user equipment, checks to see if the static part of the page has changed. The fact is that the static parts of the page can also sometimes change. These changes occur much less frequently than in the case of dynamic parts. They are not systematic, but episodic in nature and are usually associated with updating the style of the site by its creators. For example, the site developer decided to replace any picture on the page or simply changed the background of the entire site. For more correct operation of the proposed method and system, it is advisable to track these changes in the static part of the pages and make corrections accordingly. For these purposes, it is customary to use a checksum mechanism that works according to the following principle. The checksum of the static part is calculated and stored in the storage device in the cache overhead. When the user visits the page again, when the dynamic part is executed, the checksum of the updated page is re-calculated and compared with the old amount. If they do not match, then the server concludes that the static part of the page is out of date and a new page is being rewritten to the cache. Thus, the system automatically, without human intervention, monitors such changes in the static part.

In this regard, in order to correctly take into account possible changes in the static part of the requested web page, the proposed method (and, hence, the proposed system with corresponding changes) may include an additional step of calculating the checksum of the composite code 110 by the web server 10 after the step its formation when the user first accesses the web page 100, as well as the following steps that are performed after the web server 10 sends the actual html code of the dynamic parts 101, 102, 103 to the equipment 50 floors zovatelya:

- the formation by the web server 10 of the updated html code of the web page 100 including the actual html code of the static part and the specified actual html code of the dynamic parts 101, 102, 103;

- replacement by the web server 10 in the updated html code of the web page 100 of the indicated code relating to the dynamic parts 101, 102, 103, with a JS script containing a prescription for receiving the actual code of these dynamic parts 101, 102, 103 from the web server 10, with the formation of an updated composite code 110;

- calculating by the web server 10 the checksum of the updated composite code 110 and reconciling the sum of the updated composite code with the previous sum of the composite code and, if the amounts do not match, then the server 10 stores the updated composite code 110 in the storage device 15 for future use.

With this configuration of the web server, it will automatically monitor for possible changes in the static part. Moreover, if the amount of the updated composite code and the previous amount of the composite code are different, the web server 10 may issue the updated html code of the web page 100 to the user equipment 50 to display the updated web page 100 by a browser installed on the user equipment 50. In this case, the user equipment will redraw the web page 100 displayed in the browser, making allowance for the change in the static part of the web page. The last action, however, is not strictly necessary, since the subsequent user will in any case receive the web page in its updated form by updating the saved composite code, while the only case of a mismatch between the displayed static part and the real part can be neglected in view of its extreme rarity.

In addition, if you replace the old composite code with an updated one, the previous composite code may not be deleted, but rewritten with a new name. Thus, the developer gets the opportunity to compare the old and new code to identify the reasons for the appearance of the updated cache file, which is very informative when finding errors in programming.

According to another embodiment of the invention, the web server 10 can be configured to simulate a first access of the user equipment 50 to the web page 100. In particular, this can be done using a software module that simulates a user access to the web page. In this case, the web server generates a composite code 110 of web pages in advance without waiting for requests from real users, so that the next user who accesses the page can take advantage of the technology proposed in the present invention.

Meanwhile, this option, although it has the right to exist, is not preferred. From a practical point of view, it is better if the first access to the page comes from a real user. There are several reasons for this. Firstly, as a rule, there are a lot of pages on a site, and for them to be bypassed by a software module, significant computing resources are required. Secondly, many pages are not particularly attractive to the user, and there is no point in specially crawling and caching them. Thirdly, pages may become outdated, and again they need to be updated, which again entails computational overhead. The main embodiment of the invention is much simpler and more practical - users themselves by their visit vote for the most interesting and frequently requested pages. Accordingly, they themselves define and create important, from the point of view of Internet users, composite pages. It turns out more economically and efficiently, and easier for site developers.

The present invention has been disclosed above by way of example only certain embodiments thereof, which should not be construed as conditions limiting the scope of legal protection of the invention. The Applicant considers it appropriate to note that various changes, additions and modifications may be made to the indicated presented options that do not lead to a change in the essence of the present invention, and therefore all these changes, additions and modifications should be regarded as falling within the scope of the claims of the invention defined by its attached claims .
