Embodiment

For the application's above-mentioned purpose, feature and advantage can be become apparent more, below in conjunction with the drawings and specific embodiments, the application is described in further detail.

The application's core idea is, makes to embed the shell of IE kernel browser, can control voluntarily the download of browser kernel, and sends the data after downloading back to IE kernel, allows it continue to carry out the work of resolving, carrying out, playing up.

With reference to figure 1, show the flow chart of steps of page-downloading control method embodiment of a kind of IE kernel browser of the application, specifically can comprise the following steps:

Step 101, startup IE kernel browser process, and start preset downloading process;

In the embodiment of the present application, described IE kernel browser process refers to and adopts IE(Internet Explorer) browser process of browser kernel.In prior art, browser kernel is responsible for the page to download, resolve, carry out, play up, and in the present embodiment, the only operation for completing parsing, carrying out, play up of IE browser kernel, the operation of download is completed by preset downloading process.

Be well known that, process is a program of carrying out, the program example moving in computing machine; It can be distributed to processor and be carried out by processor as an entity.From the user point of view, browser process can be understood as the process of the browser representative starting in task manager.

Described downloading process can be understood as the another one process of IE kernel browser, is a process that is specifically designed to down operation.Be that described downloading process is specifically designed to download, and do not do other operations.A kind of example as the embodiment of the present application specific implementation, it is Microsoft Windows HTTP Services that the full name of WinHTTP(WinHTTP can be used in described downloading process inside, it offers HTTP client application program interface of developer, by this API, by http protocol, send request to other http server) realize a downloader, and a download manager.Be in described downloading process, to comprise a download manager and some downloaders, wherein, described download manager can be controlled page-downloading for the download rule according to default, such as the request to downloaded resources sort, optimization etc.; Downloader can be for realizing concrete down operation, and by download manager to IE kernel browser process report download situation, i.e. download status information.In practice, this downloading process, just as a service, is waited for called at any time after startup.

In the embodiment of the present application, during described IE kernel browser process initiation, described downloading process also can start, and in other words, described IE kernel browser process initiation can trigger described downloading process and start, to guarantee the page normally representing in browser.

Step 102, in described IE kernel browser process registering communication agreement, wait for the page-downloading request based on respective communication agreement;

In specific implementation, described in IE kernel browser process the step of registering communication agreement can be, use the RegisterNameSpace method of IInternetSession interface, registering communication agreement in IE kernel browser process, described communication protocol can comprise http agreement, https agreement, mailto agreement and File Transfer Protocol etc.

Particularly, the RegisterNameSpace method of IInternetSession interface, required the interface of a set form, use this method in IE kernel browser process after registering communication agreement, the page-downloading request of all employing respective communication agreements, capital is sent to default shell interface, when there is the page-downloading request of any employing respective communication agreement (as http, https agreement, mailto agreement, File Transfer Protocol), default shell interface can be notified or call to IE kernel.

Step 103, when described IE kernel browser process is received page-downloading request, trigger described downloading process and control page-downloading according to default download rule, and to IE kernel browser process, return to download status information in described page-downloading process.

In specific implementation, during the Start method of the IInternetProtocol interface providing in communication protocol registration process when IE kernel calls, by striding course, communicate by letter, page-downloading request is sent to downloading process, and return to operational character E_PENDING, notice IE kernel operations is just in commission.After downloading to data, downloading process can be notified the IE kernel browser process of initiating download, the correlation technique of the IInternetProtocolSink interface that IE kernel browser process transfer IE kernel provides, notice IE kernel download progress, the download status information such as data that download to.

More specifically, striding course communication, refer to and forward the request of a process to another process, refer in the present embodiment forward the page-downloading request of IE kernel browser process to downloading process, and in downloading process, in real time to download status information such as IE kernel report download progress and downloading datas.Striding course communication can be used windows message mechanism, and coordinates kernel objects to carry out data transmission.For example, in IE browser process, registered after http agreement, once there be the page-downloading request based on http agreement will deliver in default browser shell.When described in IE kernel calls when shell, the relevant information of this page-downloading request all can be passed over, shell can (be put into these information package in a data block, in data block, mainly comprise url, refresh, cookie etc.), then the standard pipe providing by Windows system is communicated by letter, and this data block is sent to downloading process.The windows messaging sending to browser process in downloading process is mainly the progress of telling the current download of browser.

In brief, striding course communication is both sides, and first, IE kernel browser process is received after page-downloading request, can communicate by letter by striding course, tells that those files of downloading process need to download.On the other hand, in download request implementation, downloading process can send message to IE kernel browser process, notifies the download status information such as its download progress, downloading data.

In a preferred embodiment of the present application, in described step 103, when IE kernel browser process is received page-downloading request, trigger described downloading process and specifically can comprise following sub-step according to the step of default download rule control page-downloading:

Sub-step S11, when IE kernel browser process is received page-downloading request, described page-downloading request is sent to downloading process;

Sub-step S12, downloading process are added into described page-downloading request in the download task list generating in advance;

Sub-step S13, obtain page resource type corresponding to described page-downloading request, in described download task list, according to described page resource type to page-downloading request sort;

Sub-step S14, process the page-downloading request in described download task list successively, carry out corresponding page-downloading operation.

In practice, described page-downloading request comprises URL information, and described URL information comprises extension name information, and in this case, page resource type corresponding to described page-downloading request can be by reading described extension name acquisition of information.

The present embodiment relates generally to by resource and sorts and download the scheme of optimizing, to control in the process of downloading and realize in downloading process, that is to say, when browser process receives IE download request, trigger downloading process and carry out download, before formal download the by downloader, download manager can sort to resource corresponding to download request.

In actual applications, the preferential file of download text type (as the file of the types such as html, css, js), by the file of multimedia type (as the file of the large resources such as picture, flash) by rear download, because the representing and do not rely on them of webpage.In download manager in downloading process, have a download task list, according to priority, can determine the downloading task newly increasing is put into that position in this table.Such as, the file of html, css, these text of js is all that webpage is necessary while opening, thus can put into this table before.The file of the multimedia types such as other picture, flash is put into table tail.Downloader can be from gauge outfit ceaselessly the task of getting start to download.So just realized resource sequence.

In practice, the corresponding downloading task of each page-downloading request, each downloading task resource type is a kind of.

For example, suppose to access http://www.360.cn/ in browser, IE kernel can produce 5 download requests, and the content/type of request/order is 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 producing consistent order with IE download request, above-mentioned page-downloading request is sent to downloading process from IE kernel browser process.

Suppose that the download task list in present downloading process is sky.When we receive the page-downloading request of http://www.360.cn/index.htm, because table is empty, directly put into queue.As shown in table 1, in current download task list, only have a request.

Table 1:

index.htm

Next receiving the page-downloading request of http://www.360.cn/360safe.css, by its extension name, can learn that this is a text, is the same rank with htm, so be directly put into the back location of first list item in download task list.As shown in table 2, the request sequence situation in current download task list is:

Table 2:

index.htm
	360safe.css

Continue to receive the page-downloading request of http://www.360.cn/product.swf, by its extension name, can learn that it is a flash file, because the file of this type is maximum, so put into the most end position of table.

As shown in table 3, the request sequence situation in current download task list is:

Table 3:

index.htm
	360safe.css

product.swf

Continue to receive the page-downloading request of http://www.360.cn/360safe.png, by its extension name, can learn that it is a picture file, because the size of this type of file is greater than text but is less than the file of flash type, so be inserted into the centre of text and flash type.

As shown in table 4, the request sequence situation in current download task list is:

Table 4:

index.htm
	360safe.css
360safe.png
	product.swf

Continue to receive the request of http://www.360.cn/frame.htm, by its extension name, can learn that it is a htm file, so be inserted into the back location of all text.

As shown in table 5, the request sequence situation in current download task list is:

Table 5:

index.htm
	360safe.css
frame.htm
	360safe.png
product.swf

So just generated download task list.This download task list is different from raw requests order, according to this download task list, downloads, and the preferential download text of meeting, guarantees that word shows as early as possible, next Shows Picture, and finally just takes turns to larger flash.

In another preferred embodiment of the present application, in described step 103, when IE kernel browser process is received page-downloading request, trigger described downloading process and specifically can comprise following sub-step according to the step of default download rule control page-downloading:

Sub-step S21, when IE kernel browser process is received page-downloading request, described page-downloading request is sent to downloading process;

Sub-step S22, downloading process are obtained document size information corresponding to described page-downloading request;

Sub-step S23, judge that whether described document size information surpasses default file size threshold value, the mode that if so, adopts multithreading to download is carried out the down operation of respective page, otherwise, adopt the mode of single-threaded download to carry out the down operation of respective page.

Thread can be understood as the passage of download, single-threaded download is exactly for download channel of a file opening, multithreading is downloaded and for a file, is opened a plurality of download channel exactly simultaneously, and particularly, it is exactly that the while is to the different piece of the single file of server request in fact that multithreading is downloaded.

The present embodiment relates generally to the download prioritization scheme that carries out multithreading download by the large file for surpassing predetermined threshold value, to control in the process of downloading and realize in downloading process, that is to say, when browser process receives IE download request, trigger downloading process and carry out download, in formal download the by downloader, download manager can judge whether current file size surpasses predetermined threshold value, if so, controlling downloader adopts the mode of multithreading download to download file corresponding to current page download request.

In specific implementation, only need to server communication once, as send the http request of a standard, can get file size, and, whether support the information such as multithreading download.By such as flash, the file of the multimedia types such as picture can be larger, for actual demand, file size threshold value can be set, and such as 1M, when surpassing 1M, starts multithreading and download.

Sub-step S31, when IE kernel browser process is received page-downloading request, described page-downloading request is sent to downloading process;

Whether the file that sub-step S32, downloading process are asked according to described page-downloading request judgement is write in buffer memory in advance, if so, from buffer memory, extracts this document; If not, according to described page-downloading request, from server, download corresponding file, and this document is write to buffer memory.

More preferably, described when IE kernel browser process is received page-downloading request, trigger described downloading process and also comprise according to the step of default download rule control page-downloading:

Before the step of downloading at extraction document from buffer memory, whether the time that inquiry this document writes buffer memory surpasses the default time limit, if so, according to page-downloading request, from server, downloads corresponding file, and this document is write to buffer memory.

The present embodiment relates generally to the download prioritization scheme of buffer memory read-write, to control in the process of downloading and realize in downloading process, that is to say, when browser process receives IE download request, trigger downloading process and carry out download, before formal download the by downloader, download manager can judge it is to read or download in real time from buffer memory, after formal download the by downloader, the data after downloading are write to buffer memory.

In concrete application, can decide according to the actual requirements certain file whether write buffer memory, certain file buffer memory whether can directly use etc.For example, if certain file had just carried out renewal in local cache, in a few minutes, can not remove server communication completely, directly read the file in local cache.Or as, with browser access http://www.360.cn/index.htm, first check that this file whether in buffer memory, if not, first downloads and then put into buffer memory.If had, can needn't remove server communication completely, directly use, so just accelerated access speed.

The present embodiment in practice more preferred way is, when each IE starts, do not carry out to the whether expired operation of the corresponding buffer memory of server request, but allows user first use cache access.After access, then carry out inspection and the renewal of buffer memory.Certainly, when the strategy here also can finally upgrade with reference to used buffer memory.If just upgraded soon, such as only clock or several hours in a measure, just can first use buffer memory to reexamine.If but buffer memory is before several days, also can just carry out buffer memory inspection when starting, to avoid user to be old content.

The all right applied in any combination of above-mentioned download prioritization scheme, for making those skilled in the art understand better the application, below provides the example of several applied in any combination:
