PAGE DOWNLOAD CONTROL METHOD, SYSTEM AND PROGRAM FOR IE CORE BROWSER

TECHNICAL FIELD

The present invention relates to a technical field of a browser, and especially to a method of webpage download control for an IE kernel browser and a system and a program of webpage download control for an IE kernel browser.

BACKGROUND ART

The most important part of a browser is a “Rendering Engine” which might mean “interpreting engine” and which is generally referred to as “browser kernel”. The browser kernel is responsible for interpreting the syntax of the webpage (such as HTML and JavaScript) and rendering (displaying) a webpage. Therefore, the so called browser kernel usually is an engine which performs downloading, parsing, executing and rendering on the webpage. The engine determines that how the browser display the content of the webpage and the format information of a page.

Currently, browsers popular on the market can be roughly divided into two types according to the manners of implementation:

In the first type, the developer of the browser develops not only the development of the browser kernel but also the development of a product. Examples of this type of browser are as follows: the Chrome browser, the Firefox browser, the Safari browser, the Internet Explore browser, and so on.

In the second type, the developer of the browser only develops the product, using the kernel completed by other browser producer and embedding it into its own browser. Examples of this type of browser are as follows: the 360 security browser, the Maxthon browser, TheWorld Browser, the Sogou browser and so on. These browsers often employ the kernel of the Internet Explorer browser and may be commonly referred to as “a browser using an IE kernel”.

Currently, all the IE kernel browsers available on the market were implemented directly by using a WebBrowser module provided by a system. A particular method is: creating the WebBrowser module first by an OleCreate API (Application Programming Interface), acquiring a window created by the module, embedding it into a browser window, then, calling an interface provided by the WebBrowser module to access to a Website. Throughout the process of the access, downloading, parsing, executing and rendering the webpage are performed by a code of the WebBrowser module itself. Shell program is only required to receive a notice returned from the module and accordingly change the content of the page.

For the purpose of facilitating a developers' use, interfaces provided by IE kernel are very limited. Generally, only basic interfaces such as access to webpage, stop, refresh, back and the like are available. Therefore only simple controls on the page, such as access to URL, refresh, stop, back and the like, can be achieved. For many internal situations, browser developers have no information and are unable to control. Especially, page download process can not be controlled, thus affecting the efficiency and stability of the page download.

To sum up, a technical problem needed to be addressed eagerly by the skilled in the art is how to effectively control the page download process of the IE kernel browser, in order to improve the efficiency and stability of the page download.

DETAILED DESCRIPTION OF THE EMBODIMENTS

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

In the embodiment of the present invention, a shell program embedded into IE browser kernel may be allowed to a control download of a browser kernel by itself and transmit downloaded data to an IE kernel to continue the operations of parsing, executing and rendering.

FIG. 1 is a flowchart schematically illustrating a method of webpage download control for an IE kernel browser according to a first method embodiment of the present invention. Referring to FIG. 1, the method may specifically include the following steps:

At step 101, start an IE kernel browser process and start a preset download process;

In the embodiment of the present invention, the IE kernel browser process refers to a browser process employing the kernel of an IE (Internet Explorer) browser. In the prior art, the browser kernel is responsible for downloading, parsing, executing and rendering a webpage; while in this embodiment, the kernel of the IE browser is arranged to complete the operations of parsing, executing and rendering only, and the download operation may be implemented by the preset download process.

As it is well known, a process is a program being executed, which is a routine operating in a computer; the process may be assigned to a processor executed by it as a single entity. From the angle of a user, the browser process can be understood as a process on behalf of the browser being operated in a task manager.

The download process can be understood as an additional process of the IE kernel browser, which is a process specially set for the download operation. That is, the download process is specially set for download, rather than do other operations. As a specific example implemented by the embodiment of the present invention, the interior of the download process may use WinHTTP (Microsoft Windows HTTP Services, which provide a developer with an HTTP client application programming interface (API), through which a request may be sent to other HTTP server by an HTTP protocol) to implement a downloader and a download manager. It means that the download process may include a download manager and downloaders, wherein the download manager can be set to control the page download according to a preset download rule (for example, to order and optimize a request for download a resource); the downloader can be set to implement the specific download operation and report a download state (i.e., download status information) to the IE kernel browser process through the download manager. In practice, the download process, like a service, is waiting to be called at any time after starting.

In the embodiments of the invention, the download process may be started when the IE kernel browser process is started, or in other words, the activation of the IE kernel browser process may trigger the download process to ensure the normal exhibition of a page in the browser.

At step 102, register a communication protocol in the IE kernel browser process, and wait for a page download request based on a corresponding communication protocol;

In the specific implementation, the step of registering a communication protocol in the IE kernel browser process may be: registering the communication protocol in the IE kernel browser process by using the RegisterNameSpace method of an IInternetSession interface. The communication protocol may include a http protocol (HyperText Transmission Protocol), a https protocol (SecureHypertextTransferProtocol), a mailto protocol (e-mail protocol), an FTP protocol (FileTransferProtocol) and so on.

Specifically, the RegisterNameSpace method of the IInternetSession interface requests a fixed format interface, and after registering the communication protocol in the IE kernel browser process by using this method, all the page download request employing the corresponding communication protocol may be sent to a pre-set shell interface. That is, when there is any page download request employing the corresponding communication protocol (such as the http protocol, the https protocol, the mailto protocol and the FTP protocol), the IE kernel may inform or call the preset shell interface.

At step 103, when the IE kernel browser process receives the page download request, trigger the download process to control a page download according to a preset download rule, and return download status information to the IE kernel browser process during the page download procedure.

In the specific implementation, when the IE kernel calls a Start method of the IInternetProtocol interface provided in the procedure of registering the communication protocol, the page download request may be sent to the download process through cross-process communication and an operator E_PENDING is returned to inform the IE kernel of the operation being executed. After data is downloaded, the download process may inform the IE kernel browser process which initiates the download, and then the IE kernel browser process may call a corresponding method of the IInternetProtocolSink interface provided by the IE kernel to inform the IE kernel of the download status information such as download progress and downloaded data.

More specifically, the cross-process communication means transmitting a request of a process to another process. In the present embodiment, it means transmitting the page download request of the IE kernel browser process to the download process, and during the download procedure, the download status information such as download progress and downloaded data is real-time reported to the IE kernel. The cross-process communication can use a Windows message mechanism and perform data transmission with the kernel object cooperated. For example, after the http protocol is registered in the IE browser process, once a page download request based on the http protocol is presented, it will be sent to a preset browser shell. When the IE kernel calls the shell, it may transmit the corresponding information of the page download request thereto, and the shell may pack the information (store it into a data block that mainly includes url, refresh, cookie, etc.) and send this data block to the download process via a standard channel communication provided by a Windows system. A Windows message sent to the browser process during the download procedure mainly informs the browser of the current download progress.

In short, the cross-process communication refers to two sides. Firstly, when the IE kernel browser process receives a page download request, it may inform the download process of a file to be downloaded through the cross-process communication. On the other hand, when the download request is being executed, the download process may send a message to the IE kernel browser process to inform it of the download status information such as the download progress and the downloaded data.

In a preferred embodiment of the present invention, at step 103, the step of, when the IE kernel browser process receives the page download request, triggering the download process to control a page download according to a preset download rule may specifically include the following sub-steps:

At sub-step S11, when the IE kernel browser process receives the page download request, send the page download request to the download process;

At sub-step S12, add, by the download process, the page download request to a pre-generated download task list;

At sub-step S13, acquire a page resource type corresponding to the page download request, and in the download task list, order the page download request according to the page resource type; and

At sub-step S14, sequentially process the page download request in the download task list to execute a corresponding page download operation.

In practice, the page download request may include URL information and the URL information may include extension name information. In this case, the page resource type corresponding to the page download request can be acquired by reading the extension name information.

This embodiment mainly refers to a scheme for optimizing the download by ordering the resource, which is implemented during the control of download by the download process. That is, when the browser process receives the IE download request, the download process is triggered to perform the download, and before starting the download by the downloader, the download manager may order the resource corresponding to the download request.

In a practical application, the type of a text file (such as html, css, js and the like) may be downloaded preferentially, and the type of a multimedia file (such as image, flash and other large-sized files) may be downloaded later because the exhibition of a webpage is not dependent on them. A download task list may be included in the download manager of the download process. The location where a new added download task is to be positioned in the list may be determined according to a priority. For example, since the type of the text file such as html, css and js is necessary when opening a webpage, they are positioned to the top of the list, while other multimedia type of the file such as an image and a flash is located to the end of the list. The downloader may continuously acquire tasks from the head of list to start the download. This may realize the ordering of the resource.

In practice, each of page download requests corresponds to a download task, and each of download tasks corresponds to a page resource type.

For example, assuming that the browser is visiting http://www.360.cn/, the IE kernel will generate 5 download requests, content/type/sequence of which are as follows:

http://www.360.cn/index.htm;

http://www.360.cn/360safe.css;

http://www.360.cn/product.swf;

http://www.360.cn/360safe.png;

http://www.360.cn/frame.htm.

According to a sequence consistent with the IE download request, the page download request may be sent to the download process from the IE kernel browser process.

It is assumed that the download task list in the download process is null now. When the page download request from http://www.360.cn/index.htm is received, since the list is null, it will be directly listed into a queue. As shown in Table 1, only one request is presented in the download task list.

TABLE 1

index.htm

It is known that the following page download request received from http://www.360.cn/360safe.css is a text file through its extension name, which has the same level as htm, and thus it may be positioned directly behind the first item in the download task list. As shown in Table 2, the current status of a request sequence in the download task list is as follows:

TABLE 2

index.htm

360safe.css

It is known that the following page download request received from http://www.360.cn/Product SWF is a flash file through its extension name. Since the size of this type of file is largest, it will be positioned to the bottom of the list.

As shown in Table 3, the current status of the request sequence in the download task list is as follows:

TABLE 3

index.htm

360safe.css

product.swf

It is known that the following page download request received from http://www.360.cn/360safe.png is an image file through its extension name. Since the size of this type of file is larger than the text file but less than the flash file, it may be interposed between the text type and the flash type.

As shown in Table 4, the current status of the request sequence in the download task list is as follows:

TABLE 4

index.htm

360safe.css

360safe.png

product.swf

It is known that the following page download request received from http://www.360.cn/frame.htm is an htm file through its extension name, and then it may be inserted behind all the text files.

As shown in Table 5, the current status of the request sequence in the download task list is as follows:

TABLE 5

index.htm

360safe.css

frame.htm

360safe.png

product.swf

As such, a download task list has been generated. The sequence of the download task list is different from that of an original request. When downloading according to the download task list, preferentially download the text files to ensure texts to be displayed as soon as possible, and then display images and finally the flash files having relatively large sizes.

In another preferred embodiment of the present invention, at step 103, the step of, when the IE kernel browser process receives the page download request, triggering the download process to control a page download according to a preset download rule may specifically include the following sub-steps:

At sub-step S21, when the IE kernel browser process receives the page download request, send the page download request to the download process;

At sub-step S22, acquire, by the download process, file size information corresponding to the page download request; and

At sub-step S23, determine whether the file size information exceeds a preset threshold value of file size, wherein if so, employ a multi-threaded download to perform the download operation of a corresponding page; and otherwise, employ a single-threaded download to perform the download operation of the corresponding page.

The thread can be understood as a download channel. The single-threaded download means to open one download channel for a file, and the multi-threaded download means to simultaneously open a plurality of download channels for a file. Specifically, in fact, the multi-threaded download is to request various portions of a single file to the server at the same time.

This embodiment mainly involves a scheme for optimizing the download by employing the multi-threaded download for a large file in excess of a preset threshold, which is implemented during the control of the download by the download process. That is, when the browser process receives an IE download request, the download process is triggered to perform the download, and when the downloader starts downloading, the download manager may determine whether a current file size exceeds a preset threshold, wherein if so, the downloader is controlled to employ a multi-threaded download to download a file corresponding to a current page download request.

In the specific implementation, upon only once communication to the server (for example, send a standard http request), the information such as a file size and whether to support the multi-threaded download can be obtained. Usually, the multimedia type of a file such as the flash, the image may be relatively large. Therefore, a file size threshold, such as 1M, may be set as necessary. In that case, when the size of a file exceeds 1M, the multi-threaded download may be started.

At sub-step S31, when the IE kernel browser process receives the page download request, send the page download request to the download process; and

At sub-step S32, determine, the download process, whether the requested file has been written into a cache in advance according to the page download request, wherein if so, extract the file from the cache; if not, download a corresponding file from a server according to the page download request and write the file into the cache.

More preferably, the step of, when the IE kernel browser process receives the page download request, triggering the download process to control a page download according to a preset download rule may further include:

Before the step of extracting the file from the cache to download, query whether the time when the file was written into the cache exceeds a preset time period, and if so, download the corresponding file from the server according to the page download request and write the file into the cache.

This embodiment mainly involves a scheme for optimizing download by reading from and/or writing into the cache, which is implemented during the control of the download by the download process. That is, when the browser process receives an IE download request, trigger the download process to perform the download, and before the downloader starts downloading, the download manager may determine whether to read from the cache or to real-time download; after the downloader starts downloading, the downloaded data may be written into the cache.

In a specific application, it may be decided whether to write a file into the cache and to directly use a file that has been stored in the cache, as needed in practice. For example, if a file has just been updated in a local cache, there is no need to do a server communication in a few minutes but directly read the file from the local cache instead. Or for example, before the browser visits http://www.360.cn/index.htm, it may check whether the files are stored in the cache, wherein if not, download and store them in the cache; or if so, there is no need to do the server communication but directly use them, thereby increasing the speed of access.

More preferable action of the present embodiment in practice is in that, the operation of requesting whether the corresponding cache expires to the server is not performed every time when the IE is started, but a user is allowed to use a cache access first. After the access, check and update the cache. Of course, reference may be further made here to the last time the cache updated. If the cache has just been updated (such as a few minutes or a few hours ago), the cache may be used followed by being checked. On the other hand, if the cache was updated a few days ago, a cache check could be made at the time of being started to avoid the user from obtaining outdated contents.

Above-mentioned schemes for optimizing download can also be combined. In order for the skilled person in this art to better understand the present invention, there is provided several examples of combinations:

Example 1

The step of, when the IE kernel browser process receives the page download request, triggering the download process to control a page download according to a preset download rule may specifically include the following sub-steps:

At sub-step S76, sequentially process the page download request in the download task list to acquire file size information corresponding to the page download request; and

At sub-step S77, determine whether the file size information exceeds a preset threshold value of file size, wherein if so, employ a multi-threaded download to perform the download operation of the corresponding page; and otherwise, employ a single-threaded download to perform the download operation of the corresponding page.

Of course, above-mentioned schemes for optimizing the download of various embodiments and combinations thereof are used only for illustration. It is feasible for a person skilled in the art to employ other optimized download methods, and thus there is no need for the present invention to limit it.

In a specific implementation, the embodiments of the present invention may also comprise the following steps:

At step 104, the IE kernel browser process performs parsing, executing and/or rendering operations on the downloaded page data based on the download status information.

When the download operation is completed by the download process, return the downloaded data to the IE kernel to continue the operations of parsing, executing and rendering.

FIG. 2 is a flowchart schematically illustrating a method of webpage download control for an IE kernel browser according to a second method embodiment of the present invention. Referring to FIG. 2, the method may specifically include the following steps:

At step 201, start an IE kernel browser process and start a preset download process;

In the embodiment of the present invention, the IE kernel browser process refers to a browser process employing the kernel of an IE (Internet Explorer) browser. In the prior art, the browser kernel is responsible for downloading, parsing, executing and rendering a webpage; while in this embodiment, the kernel of an IE browser is arranged to perform the operations of parsing, executing and rendering only, and the download operation may be implemented by the preset download process.

The download process can be understood as an additional process of the IE kernel browser, which is a process specially set for the download operation. That is, the download process is specially set to download, rather than do other operations. As a specific example implemented by the embodiment of the present invention, the interior of the download process may use WinHTTP (Microsoft Windows HTTP Services, which provide developers with an HTTP client application programming interface, through which a request may be sent to other HTTP servers by an HTTP protocol) to implement a downloader and a download manager. It means that the download process may include a download manager and downloaders, wherein the download manager can be set to control the page download according to a preset download rule (for example, to order and optimize requests for download a resource); the downloaders can be set to implement the specific download operation and report a download state (i.e., download status information) to the IE kernel browser process through the download manager. In practice, the download process, like a service, is waiting to be called at any time after being started.

At step 202, register a communication protocol in the IE kernel browser process, and wait for a page download request based on a corresponding communication protocol;

In the specific implementation, the step of registering a communication protocol in the IE kernel browser process may be to register the communication protocol in the IE kernel browser process by using the RegisterNameSpace method of an IInternetSession interface. The communication protocol may include an http protocol, an https protocol, a mailto protocol, an FTP protocol and so on.

Specifically, the RegisterNameSpace method of the IInternetSession interface requests a fixed format interface, and after registering the communication protocol in the IE kernel browser process by using this method, all the page download requests employing the corresponding communication protocol may be sent to a pre-set shell interface. That is, when there is any page download request employing the corresponding communication protocol (such as the http protocol, the https protocol, the mailto protocol and the FTP protocol), the IE kernel may inform or call the preset shell interface.

At step 203, when the IE kernel browser process receives the page download request, send the page download request to the download process;

At step 204, add, by the download process, the page download request to a pre-generated download task list;

At step 205, acquired page resource type corresponding to the page download request, and in the download task list, order the page download request according to the page resource type;

In practice, the page download request may include URL information and the URL information may include the extension name information. In this case, the page resource type corresponding to the page download request can be acquired by reading the extension name information.

At step 206, sequentially process the page download request in the download task list to perform a corresponding page download operation;

At step 207, return download status information to the IE kernel browser process during the page download procedure.

When data is downloaded, the download process may inform the IE kernel browser process which initiates the download, and then the IE kernel browser process may call a corresponding method of the IInternetProtocolSink interface provided by the IE kernel to inform the IE kernel of the download status information such as download progress and downloaded data.

More specifically, the cross-process communication means to transmit a request of a process to another process. In the present embodiment, it means to transmit the page download request of the IE kernel browser process to the download process, and during the download procedure, the download status information such as the download progress and the downloaded data is real-time reported to the IE kernel. The cross-process communication can use a Windows message mechanism and perform data transmission with the kernel object cooperated. For example, after the http protocol is registered in the IE browser process, once the page download request based on http protocol is presented, it will be sent to a preset browser shell. When the IE kernel calls a shell, it may transmit the corresponding information of the page download request thereto, and the shell may pack the information (store it into a data block that mainly includes url, refresh, cookie, etc.) and send this data block to the download process via a standard channel communication provided by a Windows system. A Windows message sent to the browser process during the download procedure mainly inform the browser of the current download progress.

In short, the cross-process communication refers to two sides. Firstly, when the IE kernel browser process receives a page download request, it may inform the download process of the file to be downloaded through the cross-process communication. On the other hand, when the download request is being executed, the download process may send a message to the IE kernel browser process to inform it of the download status information such as the download progress and the downloaded data.

This embodiment mainly refers to a scheme for optimizing the download by ordering a resource, which is implemented during the control of the download by the download process. That is, when the browser process receives the IE download request, trigger the download process to perform the download, and before starting the download by the downloader, the download manager may order the resource corresponding to the download request.

In practical applications, the type of a text file (such as html, css, js and the like) may be downloaded preferentially, and the type of a multimedia file (such as image, flash and other large-sized files) may be downloaded later because the exhibition of the webpage is not dependent on them. A download task list may be included in the download manager of the download process. The location where a new added download task is to be positioned in the list may be determined according to a priority. For example, since the type of the text file such as html, css and js is necessary when opening a webpage, an is positioned to the top of the list, while other multimedia type of a file such as an image and a flash are located to the end of the list. The downloader may continuously acquire tasks from the head of list to start the download. This may realize the ordering of the resource.

In practice, each of page download requests corresponds to a download task, and each of download tasks corresponds to a page resource type.

In a preferred embodiment of the present invention, at step 206, the step of performing the corresponding page download operation may include the following sub-steps:

At sub-step S21, acquire file size information corresponding to the page download request;

At sub-step S22, determine whether the file size information exceeds a preset threshold value of file size; if yes, go to sub-step S23, and if not, go to sub-step S24;

At sub-step S23, employ a multi-threaded download to perform the download operation of a corresponding page; and

At sub-step S24, employ a single-threaded download to perform the download operation of the corresponding pages.

This embodiment mainly involves a scheme for optimizing the download by employing the multi-threaded download for a large file in excess of a preset threshold, which is implemented during the control of the download by the download process. That is, when the browser process receives an IE download request, the download process is triggered to perform the download, and when the downloader starts downloading, the download manager may determine whether the current file size exceeds a preset threshold, wherein if so, the downloader is controlled to employ the multi-threaded download to download a file corresponding to a current page download request.

In the specific implementation, upon only once communication to the server (for example, send a standard http request), the information such as the file size and whether to support the multi-threaded download can be obtained. Usually, the multimedia type of the file such as the flash, the image and the like may be relatively large. Therefore, a file size threshold, such as 1M, may be set as necessary. In that case, when the size of a file exceeds 1M, the multi-threaded download may be started.

FIG. 3 is a flowchart schematically illustrating a method of webpage download control for an IE kernel browser according to a third method embodiment of the present invention. Referring to FIG. 3, the method may specifically include the following steps:

At step 301, start an IE kernel browser process and simultaneously start a preset download process;

At step 302, register a communication protocol in the IE kernel browser process, and wait for a page download request based on a corresponding communication protocol;

At step 303, when the IE kernel browser process receives the page download request, send the page download request to the download process;

At step 304, determine, by the download process, whether the requested file has been written into a cache in advance according to the page download request, wherein if yes, go to step 305; otherwise go to step 307;

At step 305, query whether the time when the file was written into the cache exceeds a preset time period, wherein if not, go to step 306; or if yes, go to step 307;

At step 306, extract the file from the cache;

At step 307, add, by the download process, the page download request to a pre-generated download task list;

At step 308, acquire a page resource type corresponding to the page download request, and in the download task list, order the page download request according to the page resource type;

At step 309, sequentially process the page download request in the download task list to perform a corresponding page download operation;

At step 310, write the downloaded file into the cache.

At step 311, return download status information to the IE kernel browser process during the page download procedure.

In specific applications, it may be decided whether to write a file into the cache and to directly use a file that has been stored in the cache, as needed in practice. For example, if a file has just been updated in a local cache, there is no need to do a server communication in a few minutes but directly read the file from the local cache instead. Or for example, before the browser visits http://www.360.cn/index.htm, it may check whether the files are stored in the cache, wherein if not, download and store them in the cache; or if so, there is no need to do the server communication but directly use them, thereby increasing the speed of access.

More preferable action of the present embodiment in practice is in that, the operation of requesting whether the corresponding cache expires to the server is not performed every time when the IE starts, but a user is allowed to use the cache access first. After the access, check and update the cache. Of course, reference may be further made here to the last time the cache updated. If the cache has just been updated (such as a few minutes or a few hours ago), the cache may be used followed by being checked. On the other hand, if the cache was updated a few days ago, a cache check could be made at the time of starting to avoid the user from obtaining outdated contents.

In a specific implementation, the embodiments of the present invention may also comprise the following step:

At step 312, the IE kernel browser process performs parsing, executing and/or rendering operations on the downloaded page data based on the download status information.

When the download operation is completed by the download process, return the downloaded data to the IE kernel to continue the operations of parsing, executing and rendering.

FIG. 4 is a flowchart schematically illustrating a method of webpage download control for an IE kernel browser according to a fourth method embodiment of the present invention. Referring to FIG. 4, the method may specifically include the following steps:

At step 401, start an IE kernel browser process and start a preset download process;

The download process can be understood as an additional process of the IE kernel browser, which is a process specially set for the download operation. That is, the download process is specially set to download, rather than do other operations. As a specific example implemented by the embodiments of the present invention, the interior of the download process may use WinHTTP (Microsoft Windows HTTP Services, which provides a developer with an HTTP client application programming interface (API), through which a request may be sent to other HTTP servers by an HTTP protocol) to implement a downloader and a download manager. It means that the download process may include the download manager and the downloader, wherein the download manager can be set to control the page download according to a preset download rule (for example, to order and optimize requests for download resources); the downloader can be set to implement the specific download operation and report a download state (i.e., download status information) to the IE kernel browser process through the download manager. In practice, the download process, like a service, is waiting to be called at any time after being started.

In the embodiments of the invention, the download process may be started when the IE kernel browser process is started to ensure the normal exhibition of a page in the browser.

At step 402, register a communication protocol in the IE kernel browser process, and wait for a page download request based on a corresponding communication protocol;

Specifically, the RegisterNameSpace method of the IInternetSession interface requests a fixed format interface, and after registering the communication protocol in the IE kernel browser process by using this method, all the page download requests employing the corresponding communication protocol may be sent to a pre-set shell interface. That is, when there is any page download request employing the corresponding communication protocol (such as the http protocol, and the https protocol), the IE kernel may inform or call the preset shell interface.

At step 403, when the IE kernel browser process receives the page download request, send the page download request to the download process;

At step 404, acquire, by the download process, file size information corresponding to the page download request;

At step 405, when the file size information exceeds a preset threshold value of the file size, employ a multi-threaded download to perform the download operation of a corresponding page;

At step 406, return, by the download process, download status information to the IE kernel browser process during the page download procedure.

In a preferred embodiment of the embodiments of the present invention may also include the following step:

when the file size information is equal to or less than the preset threshold value of the file size, employ a single-threaded download to perform the download operation of the corresponding page.

In the specific implementation, when the IE kernel calls a Start method of the IInternetProtocol interface provided in the procedure of registering the communication protocol, the page download request may be sent to the download process through the cross-process communication and return an operator E_PENDING to inform the IE kernel of the operation being executed. When data is downloaded, the download process may inform the IE kernel browser process which initiates the download, and then the IE kernel browser process may call a corresponding method of the IInternetProtocolSink interface provided by the IE kernel to inform the IE kernel of the download status information such as download progress and downloaded data.

More specifically, the cross-process communication means to transmit a request of a process to another process. In the present embodiment, it means to transmit the page download request of the IE kernel browser process to the download process, and during the download procedure, the download status information such as download progress and downloaded data is real-time reported to the IE kernel. The cross-process communication can use a Windows message mechanism and perform data transmission with the kernel object cooperated. For example, after the http protocol is registered in the IE browser process, once the page download request based on the http protocol is presented, it will be sent to a preset browser shell. When the IE kernel calls the shell, it may transmit the corresponding information of the page download request thereto, and the shell may pack the information (store it into a data block that mainly includes url, refresh, cookie, etc.) and send this data block to the download process via a standard channel communication provided by a Windows system. A Windows message sent to the browser process during the download procedure mainly inform the browser of the current download progress.

In short, the cross-process communication refers to two sides. Firstly, when the IE kernel browser process receives a page download request, it may inform the download process of files to be downloaded through the cross-process communication. On the other hand, when the download request is being executed, the download process may send a message to the IE kernel browser process to inform it of the download status information such as the download progress and the downloaded data.

This embodiment of the present invention mainly involves a scheme for optimizing the download by employing the multi-threaded download for a large file in excess of a preset threshold, which is implemented during the control of the download by the download process. That is, when the browser process receives an IE download request, trigger the download process to perform the download, and when the downloader starts downloading, the download manager may determine whether a current file size exceeds a preset threshold, wherein if so, the downloader is controlled to employ the multi-threaded download to download a file corresponding to current page download request.

In the specific implementation, upon only once communication to the server (for example, send a standard http request), the information such as the file size and whether to support the multi-threaded download can be obtained. Usually, the multimedia type of files such as the flash and the image may be relatively large. Therefore, a file size threshold, such as 1M, may be set as necessary. In that case, when the size of a file exceeds 1M, the multi-threaded download may be started.

In the specific implementation, the embodiments of the present invention may also comprise the following step:

At step 407, the IE kernel browser process performs parsing, executing and/or rendering operations on the downloaded page data based on the download status information.

When the download operation is completed by the download process, return the downloaded data to the IE kernel to continue the operations of parsing, executing and rendering.

FIG. 5 is a flowchart schematically illustrating a method of webpage download control for an IE kernel browser according to a fifth method embodiment of the present invention. Referring to FIG. 5, the method may specifically include the following steps:

At step 501, start an IE kernel browser process and start a preset download process;

At step 502, register a communication protocol in the IE kernel browser process, and wait for a page download request based on a corresponding communication protocol;

At step 503, when the IE kernel browser process receives the page download request, send the page download request to the download process;

At step 504, add, by the download process, the page download request to a pre-generated download task list;

At step 505, acquire a page resource type corresponding to the page download request, and in the download task list, order the page download request according to the page resource type;

In practice, the page download request may include URL information and the URL information may include extension name information. In this case, page resource type corresponding to the page download request can be acquired by reading the extension name information.

At step 506, sequentially process the page download request in the download task list;

At step 507, acquire file size information corresponding to the page download request;

At step 508, determine whether the file size information exceeds a preset threshold value of file size; if yes, go to step 509, and if not, go to step 510;

At step 509, employ a multi-threaded download to perform the download operation of a corresponding page and then go to step 511;

At step 510, employ a single-threaded download to perform the download operation of the corresponding page and then go to step 511;

At step 511, return download status information to the IE kernel browser process during the page download procedure.

This embodiment mainly involves a scheme for optimizing the download by employing the multi-threaded download and ordering a resource, which is implemented during the control of the download by the download process. That is, when the browser process receives an IE download request, trigger the download process to perform the download, and before the downloader starts downloading, the download manager may order the resource corresponding to the download request and determine whether the current file size exceeds the preset threshold, wherein if so, the downloader is controlled to employ a multi-threaded download to download the file corresponding to current page download request.

In practical applications, the type of text file (such as html, css, js and the like) may be downloaded preferentially, and the type of multimedia file (such as image, flash and other large-sized files) may be downloaded later because the exhibition of the webpage is not dependent on them. A download task list may be included in the download manager of the download process. The location where a new added download task is to be positioned in the list may be determined according to a priority. For example, since the type of text file such as html, css and js is necessary when opening a webpage, they are positioned to the top of the list, while other multimedia type of files such as the image and the flash are located to the end of the list. The downloader may continuously acquire tasks from the head of list to start the download. This may realize the ordering of the resource.

In practice, each of page download requests corresponds to a download task, and each of download tasks corresponds to a page resource type.

When processing is provided to a large-sized file (such as, the last file, product.swf) in the download task list, it may be determined whether its size exceeds a preset threshold (such as 1M). If so, the multi-threaded download may be started. The multi-threaded download means to simultaneously open a plurality of download channels for a single file. Specifically, in fact, the multi-threaded download is to request various portions of a single file to the server at the same time.

FIG. 6 is a flowchart schematically illustrating a method of webpage download control for an IE kernel browser according to a sixth method embodiment of the present invention. Referring to FIG. 6, the method may specifically include the following steps:

At step 601, start an IE kernel browser process and start a preset download process;

At step 611, return the download status information to the IE kernel browser in the download operation process of the page, and then write the downloaded file into the cache,

This embodiment mainly involves a scheme for optimizing download by employing the multi-threaded download and reading from and/or writing into the cache, which is implemented during the control of the download by the download process. That is, when the browser process receives an IE download request, trigger the download process to perform the download, and before the downloader starts downloading, the download manager may determine whether to read from the cache or to real-time download; and determines whether the current file size exceeds the preset threshold, wherein if so, the downloader is controlled to employ the multi-threaded download to download a file corresponding to a current page download request. After the downloader starts downloading, the downloaded data may be written into the cache.

More preferable action of the present embodiment in practice is in that, the operation of requesting whether the corresponding cache expires to the server is not performed every time the IE starts, but users are allowed to use the cache access first. After the access, check and update the cache. Of course, reference may be further made here to the last time the cache updated. If the cache has just been updated (such as a few minutes or a few hours ago), the cache may be used followed by being checked. On the other hand, if the cache was updated a few days ago, a cache check could be made at the time of starting to avoid the user from obtaining outdated contents.

FIG. 7 is a flowchart schematically illustrating a method of webpage download control for an IE kernel browser according to embodiments of the present invention, and the method may specifically include the following steps:

At step S1, start an IE kernel browser process and start a preset download process;

In the embodiment of the present invention, the IE kernel browser process refers to a browser process employing the kernel of an IE (Internet Explorer) browser. In the prior art, the browser kernel is responsible for downloading, parsing, executing and rendering a webpage; while in this embodiment, the kernel of an IE browser is arranged to complete the operations of parsing, executing and rendering only, and the download operation may be implemented by the preset download process.

The download process can be understood as an additional process of the IE kernel browser, which is a process specially set for the download operation. That is, the download process is specially set to download, rather than do other operations.

It means that the download process may include the download manager and the downloader, wherein the download manager can be set to control the page download according to a preset download rule (for example, to order and optimize requests for download resources); the downloader can be set to implement the specific download operation and report the download state (i.e., download status information) to the IE kernel browser process through the download manager. In practice, the download process, like a service, is waiting to be called at any time after being started.

In the embodiment of the invention, the download process may be started when the IE kernel browser process is started to ensure the normal exhibition of a page in the browser.

At step S2, register a communication protocol in the IE kernel browser process, and wait for a page download request based on a corresponding communication protocol;

In a specific implementation, the step of registering a communication protocol in the IE kernel browser process may be to register the communication protocol in the IE kernel browser process by using the RegisterNameSpace method of an IInternetSession interface. The communication protocol may include the http protocol, an https protocol, a mailto protocol, an FTP protocol and so on.

Specifically, the RegisterNameSpace method of the IInternetSession interface requests a fixed format interface, and after registering the communication protocol in the IE kernel browser process by using this method, all the page download requests employing the corresponding communication protocol may be sent to a pre-set shell interface. That is, when there is any page download request employing the corresponding communication protocol (such as the http protocol and the https protocol), the IE kernel may inform or call the preset shell interface.

At step S3, when the IE kernel browser process receives the page download request, send the page download request to the download process;

At step S4: determines, by the download process, whether the requested file has been pre-written into a cache according to the page download request; if yes, execute step S5; otherwise, execute steps S6, S7, and S8;

At step S5: extract the file from the cache;

At step S6: download a corresponding file from a server according to the page download request;

At step S7: return the download status information to the IE kernel browser process in the download procedure;

At step S8: write the downloaded file into the cache.

In the specific implementation, when the IE kernel calls a Start method of the IInternetProtocol interface provided in the procedure of registering the communication protocol, the page download request may be sent to the download process through a cross-process communication and return an operator E_PENDING to inform the IE kernel of the operation being executed. When data is downloaded, the download process may inform the IE kernel browser process which initiates the download, and then the IE kernel browser process may call a corresponding method of the IInternetProtocolSink interface provided by the IE kernel to inform the IE kernel of the download status information such as download progress and downloaded data.

More specifically, the cross-process communication means to transmit a request of a process to another process. In the present embodiment, it means to transmit the page download request of the IE kernel browser process to the download process, and during the download procedure, real-time report the download status information such as the download progress and the downloaded data to the IE kernel. The cross-process communication can use a Windows message mechanism and perform data transmission with the kernel object cooperated. For example, after the http protocol is registered in the IE browser process, once the page download request based on the http protocol is presented, it will be sent to a preset browser shell. When the IE kernel calls the shell, it may transmit the corresponding information of the page download request thereto, and the shell may pack the information (store it into a data block that mainly includes url, refresh, cookie, etc.) and send this data block to the download process via a standard channel communication provided by a Windows system. A Windows message sent to the browser process during the download procedure mainly inform the browser of the current download progress.

In short, the cross-process communication refers to two sides. Firstly, when the IE kernel browser process receives a page download request, it may inform the download process of file to be downloaded through the cross-process communication. On the other hand, when the download request is being executed, the download process may send a message to the IE kernel browser process to inform it of the download status information such as the download progress and the downloaded data.

In a specific implementation, before step S5, it may also include the following steps:

At step S41, query whether the time when the file was written into the cache exceeds a preset time period, and if so, go to steps S6, S7 and S8; otherwise, execute step S5.

More preferable action of the present embodiment in practice is in that, the operation of requesting whether the corresponding cache expires to the server is not performed every time when the IE starts, but a user is allowed to use the cache access first. After the access, check and update the cache. Of course, reference may be further made here to the last time the cache updated. If the cache has just been updated (such as a few minutes or a few hours ago), the cache may be used followed by being checked. On the other hand, if the cache was updated a few days ago, a cache check could be made at the time of starting to avoid the user from obtaining outdated contents.

In the specific implementation, the embodiments of the present invention may also comprise the following steps:

At step S9, perform, by the IE kernel browser process, parsing, executing and/or rendering operations on the downloaded page data based on the download status information.

When the download operation is completed by the download process, return the downloaded data to the IE kernel to continue the operations of parsing, executing and rendering.

In a preferred embodiment of the present invention, the step S6 may specifically also include the following sub-steps:

At sub-step S11, add, by the download process, the page download request to a pre-generated download task list;

At sub-step S12, acquire a page resource type corresponding to the page download request, and in the download task list, order the page download request according to the page resource type; and

At sub-step S13, sequentially process the page download request in the download task list to execute a corresponding page download operation.

This embodiment mainly refers to a scheme for optimizing the download by ordering the resources, which is implemented during the control of download by the download process. That is, when the browser process receives the IE download request, trigger the download process to perform the download, and before starting the download by the downloader, the download manager may order the resource corresponding to the download request.

In a practical application, the type of text file (such as html, css, js and the like) may be downloaded preferentially, and the type of multimedia file (such as image, flash and other large-sized files) may be downloaded later because the exhibition of the webpage is not dependent on them. A download task list may be included in the download manager of the download process. The location where a new added download task is to be positioned in the list may be determined according to a priority. For example, since the type of text file such as html, css and js is necessary when opening a webpage, they are positioned to the top of the list, while other multimedia type of files such as the image and the flash are located to the end of the list. The downloader may continuously acquire tasks from the head of list to start the download. This may realize the ordering of the resource.

In practice, each of page download requests corresponds to a download task, and each of download tasks corresponds to a page resource type.

More preferably, in the step S13, the steps of sequentially processing the page download request in the download task list, and implementing the corresponding page download operation also includes:

At sub-step S13-1, acquire, by the download process, file size information corresponding to the page download request;

At sub-step S13-2, determine whether the file size information exceeds a preset threshold value of file size, wherein if so, employ a multi-threaded download to perform the download operation of a corresponding page; and otherwise, employ a single-threaded download to perform the download operation of the corresponding page.

This embodiment mainly involves a scheme for optimizing the download by employing the multi-threaded download for a large file in excess of the preset threshold, which is implemented during the control of the download by the download process. That is, when the browser process receives an IE download request, trigger the download process to perform the download, and when the downloader starts downloading, the download manager may determine whether the current file size exceeds the preset threshold, wherein if so, the downloader is controlled to employ the multi-threaded download to download the file corresponding to a current page download request.

In the specific implementation, upon only once communication to the server (for example, send a standard http request), the information such as the file size and whether to support multi-threaded download can be obtained. Usually, the multimedia type of the file such as the flash, the image and the like may be relatively large. Therefore, a file size threshold, such as 1M, may be set as necessary. In that case, when the size of a file exceeds 1M, the multi-threaded download may be started.

It should be explained that, for the sake of simplicity of description, the method embodiments are described as combination of a series of actions, whereas a person skilled in the art should be aware that the present invention is not limited by the described action sequence, and certain steps may be performed in other orders or simultaneously according to the present invention. Secondly, a person skilled in the art should be aware that the embodiments described in the specification are all preferred embodiments, while the involved actions and modules are not certainly necessary in the present invention.
