Description
Technical field
The application relates to data communication field, more particularly, to web page transmission,
The display device of web page and the transmission of web page and display system.
Background technology
Growing along with computer networking technology, people can be hundreds of by access to the Internet
The website of ten thousand and billions of web pages.When user desires access to certain web page,
Browser can be opened in address field, input the URL of this web page.Browser is based on this
URL sends the request accessing this web page to web server.Web server is in response to clear
Look at the request of device, the source code file (such as, html file) of this web page is sent to
Browser.It can be resolved after receiving the source code file of this web page by browser,
Afterwards can be for each resource (such as, Javascript file, picture, the literary composition in web page
Word, CSS etc.) send resource request to web server respectively, and from web server
After getting requested resource, corresponding content of pages is presented to user.
One web page can present polytype content, such as word, static figure
Shape, animation etc..But, browser often need not the full content in certain web page
It is concurrently presented in face of user.Each web page exists Consumer's Experience is risen decisive work
Object small set.Such as, user compares the content of care and user makes higher interior of expenditure
Hold and need preferentially to present to user, and the most unessential content and user make
The relatively low content of expenditure can slightly be delayed and presents to user.In order to user is compared care content and
The content priority that user makes expenditure higher presents to user, thus wishes to obtain from web server
To the resource relevant to this content.Therefore, it is intended that according to the content needing display in web page
Importance and make expenditure etc., to corresponding resource mark priority so that priority is higher
Resource request preferentially obtains the response of web server.
To this end, Google develops a kind of new procotol SPDY(sound together
" speedy ") agreement.SPDY agreement is the enhancing to http protocol, and it allows data stream
Multiplexing, Request Priority and HTTP Header compression.According to SPDY agreement,
Browser is the priority of appointment requested resource when asking resource, and the side of assigned priority
Case is according to predetermined rule, specifies, such as according to the different file types of different resource
* the priority of .htm file is minimum, and the priority of the script files such as * .js is taken second place, and * .jpg, * .gif,
* the priority of the picture file such as .png is the highest.
But, browser (such as Chrome and Firefox of existing support SPDY agreement
Browser) specified scheme of resource prioritization is only relied upon to the file type of resource, at certain
User cannot be met in the case of Xie different resource in different types of web page is presented preferentially
The demand of level.Such as, browse and be rendered as the user of main website with picture and wish presenting of picture
Priority is higher than word, and the user browsing the website based on information wishes that presenting of word is excellent
First level is higher than picture.And according to the resource prioritization specified scheme of SPDY agreement, to this two class
Picture in website all gives the highest priority, thus is presented to user at first.So will
The actual demand of the user of this two classes website can not be met.
Additionally, do not allow web page designer to layout not in existing web technology
With part mark priority, the most there is not the priority that can operationally carry out web content
Problem, proposes a kind of control web page in No. 200710003983.4 Chinese patent application
The method of display on the client, each content in wherein said web page is assigned not
Same priority.Described method includes: send the visit to web page from user end to server
Ask request, in response to described request, server will be used for realizing in described web page each in
The control parts of the prioritization held are sent to client, and described control parts are according to described
In web page, the order of the priority of each content is fetched content from server and shows.
But, the program is largely dependent upon the control that server returns to the support of priority
Parts processed, browser needs the most in unison, just can complete the priority scheduling of resource.
And in this scenario, the executor of priority scheduling has been placed on browser, it is browser undoubtedly
Page loading procedure with the addition of increasingly complex process logic, it is contemplated that browser place terminal sets
Standby disposal ability, may increase the page and load time delay.Meanwhile, the program do not account for right
The situation of the concurrent request of resource in one page, and during current web page browses, to one
Individual main frame is set up multiple TCP and is connected that to carry out the concurrent request of resource the most universal, merely by
The resource prioritization scheduling that browser controls, it is impossible to realize the Synchronization Control between each TCP connection,
The resource request initiated according to the order of priority not necessarily arrives service according to the order sent
Device, is the most sequentially responded by server even if sequentially arriving server, it is clear that this scheme
Cannot ensure browser in actual pages browses, the order of priority desirably gets
Resource, the most just cannot the strict priority of resource described in guarantee scheme.
Summary of the invention

Accompanying drawing explanation
Fig. 1 shows the flow chart of the web page transmission according to the application first aspect;
Fig. 2 shows the square frame of the web page display device of the second aspect according to the application
Figure.
Detailed description of the invention
The web page transmission of the first aspect according to the application is described in detail below with reference to Fig. 1
Method.
As it was previously stated, the full content in web page is not required to be concurrently presented in face of user.
Each webpage exists the object small set playing a decisive role Consumer's Experience.Such as, use
The content that the content of care is compared at family and user makes expenditure higher needs preferentially to present to user, and
The content that the most unessential content and user make expenditure relatively low can slightly delay in
Now give user.
To achieve it, according to the application, the developer of web page creating web
Importance according to resource during the page, is pre-configured with priority for different contents.As one
Concrete example, the developer of web page can be with HTML(HTML) language
Create web page, and in the label of html document, add self-defining attribute, to show
Priority with the resource that described label associates.For example, it is possible to html document link or
The labels such as img add a self-defining attribute priority, the such as following institute of the mode of interpolation
Show:
<link href=" main.css " rel=" stylesheet " type=" text/css " priority=" 1 "/>
Below only as a example by html language to create web page process how as the page in not
It is pre-configured with priority with content to have carried out exemplarily illustrating.Those skilled in the art can manage
Solve, use other Languages or mode to create web page and for the page during creating
In different content to be pre-configured with priority be also easily to realize, thus omit at this relevant
The detailed description of content.
Afterwards, the web clothes that the web page created can be disposed by the developer of web page
On business device.
Hereafter, when user desires access to this web page, browser can be opened at address field
The URL of middle this web page of input.Browser sends visit based on this URL to web server
Ask the request of this web page.Web server is in response to the request of browser, by this Web page
The source code file in face is sent to browser.Browser obtains described Web page from web server
The source code file (step 101 in Fig. 1) in face.Such as, described web page be with
In the case of html language creates, the source of the web page that browser obtains from web server
Code file is the html document of this web page.
It follows that the source code file of acquired web page is resolved by browser, with
Therefrom extract the priority (step 102) of resource in web page.For example, referring to as above
A described specific embodiment, if the developer of web page creates with html language
Web page, and in the link label of html document, with the addition of a self-defining attribute
Priority, to show the priority of related content, then the browser HTML to this web page
The value of link label, its attribute and each attribute can be separated during resolving by document,
Thus extract the value of attribute priority.
Then, browser sends resource request to web server, carries in described request
State the priority (step 103) of resource.
According to an embodiment, browser i.e. can pass through in the way of concurrent Frame
Simultaneous streaming under single TCP connection, sends described resource request to web server.The most just
It is to say, after browser is that web server establishes a TCP connection, simultaneously to web
Server sends multiple resource request.Further, described Frame comprises for indicating described money
The field of the priority in source, and the value of this field is civilian with the source code from described web page
The value of the priority of the resource extracted in part is consistent.Such as, browser can be based on SPDY
Agreement, asks described resource by sending SYN_STREAM frame to web server, its
Described in SYN_STREAM frame include the Priority of the priority for indicating described resource
Field, the value of described Priority field carries with from the source code file of described web page
The value of the priority of the resource taken out is consistent.Such as, if the developer of web page is with HTML
Language creates web page, and with the addition of one in the link label of html document and make by oneself
The attribute priority of justice, to show the priority of related content, then SYN_STREAM frame
The value of Priority field consistent with the value of the attribute priority of link label.
According to another embodiment, browser can also be to web in the way of serial data frame
Server sends described resource request.It is to say, browser can be sequentially to web services
Device sends multiple resource request.
Afterwards, web server is in response to the request of browser, according to the priority of described resource
Order sends described resource (step 104) to browser.
Such as, if browser have sent 5 resource request to web server concomitantly, point
Not with SYN_STREAM (" GET " resource1 [priority1]), SYN_STREAM
(" GET " resource 2 [priority2]), SYN_STREAM (" GET " resource
3 [priority3]), SYN_STREAM (" GET " resource 4 [priority4]),
SYN_STREAM (" GET " resource 5 [priority5]) represents.Web server is receiving
After request SYN_STREAM (" GET " resource 1 [priority1]), quickly it is carried out
Process and have sent corresponding response to browser.And process request SYN_STREAM
(" GET " resource2 [priority2]) needs to spend the more time, and its excess-three resource
Request is simultaneously in pending queue.Now web server can be according in pending queue
The sequence of the priority of three requests processes request.Such as, priority3, priority4,
The value of priority5 is respectively 2,1,3, then web server completes request
After the process of SYN_STREAM (" GET " resource2 [priority2]), meeting prioritizing selection is excellent
The SYN_STREAM (" GET " resource4 [priority4]) that first level is the highest processes.
