Fig. 1 is the system construction drawing that improves according to an embodiment of the invention web page browsing speed.With reference to Fig. 1, described system can comprise: browser, a plurality of web proxy gateway (there is shown 3, comprise 1 dynamic multiple domain name rewriting server and 2 domain name expansion servers) and web server (source station), web proxy gateway is between browser and web server.Wherein, browser is arranged in client, and browser refers to the html file content that can show web server or file system, and allows a kind of software of user and these file interactions, can be the browsers such as IE, firefox, chrome.Browser is mainly mutual by http agreement and web server and obtain webpage, and these webpages are specified by URL(uniform resource locator) (url), and file format is generally html, and is indicated in http agreement by MIME.Client can be wired or wireless communication device, for example, and computer, mobile phone, personal digital assistant (PDA) etc.In web server, store one or more webpages.
Web proxy gateway is a kind of reverse proxy, browser can obtain the webpage in web server by web proxy gateway, that is to say, to the page request of web server, first (for example http request) can arrive web proxy gateway to browser, by web proxy gateway, the page request of browser is responded, for example, return to browser after obtaining webpage from web server or local cache.In embodiments of the present invention, web proxy gateway can also be modified to html file, makes browser can from a plurality of web proxy gateways, obtain a plurality of same domain name page elements in same webpage.
Particularly, be by revising the url of element in the html page, to connect to increase browser access domain concrete number simultaneously on web proxy gateway, improve the concurrent download performance of browser.Further, can also concurrent domain concrete number be set according to http page elements type, as picture is used multiple domain name, video is used single domain name etc.Further, can also different concurrent domain concrete numbers be set according to different browsers, thus performance browser optimum performance.
Below provide the specific implementation of web proxy gateway.
Fig. 2 is the structure drawing of device that improves according to an embodiment of the invention web page browsing speed.Described application of installation, in web proxy gateway (DDNS in Fig. 1 is rewritten server), comprises the first acquiring unit 10, second acquisition unit 20, html file modification unit 30 and transmitting element 40.
The operation principle of this device is:
When the first acquiring unit 10 receives the http request of browser transmission, can obtain described http and ask corresponding html file.Whether the first acquiring unit 10, when the http request that receives browser transmission, can first judge in buffer memory and exist this http to ask corresponding html file, if so, from buffer memory, to obtain described html file; Otherwise (web server) obtains described html file from source station, and the html file getting is added in buffer memory to the html file of buffer memory (if can).
20 pairs of described html files of second acquisition unit are resolved, and obtain the same domain name page elements that described html file is quoted, and so-called with domain name page elements, refer to, the url of a plurality of page elements points to same domain name.Second acquisition unit 20 also further obtains the first quantity of the page elements that described same domain name page elements comprises.
First html file modification unit 30 judges whether described the first quantity is greater than default thresholding, if described the first quantity is greater than default thresholding, described html file is modified, the url of the second quantity page elements in described same domain name page elements is revised as and points to other web proxy gateways, wherein, described the second quantity is the poor of described the first quantity and described default thresholding.For example, in Fig. 1, DDNS is rewritten server and is received described html request, and after getting corresponding html file, described html file is rewritten, and the url of partial page element is wherein revised as and points to two other domain name expansion servers.If described the first quantity is less than or equal to default thresholding, html file is not carried out to above-mentioned modification, by transmitting element 40, directly send it to browser.
Wherein, the quantity of described other web proxy gateways is one or more, and alternatively, the quantity of the corresponding page elements of each web proxy gateway is less than or equal to described default thresholding.That is to say, when 30 pairs of html file modification unit url modifies, can be revised as and point to a plurality of web proxy gateways, and browser still can be followed the restriction of number of concurrent to the access of each proxy gateway.
Transmitting element 40 is for sending to browser by amended html file.After browser receives amended html file, described html file is resolved, the url (url of unmodified) that finds that there is partial page element points to source station, so initiate the request to this page elements to source station, this request can arrive web proxy gateway (DDNS in Fig. 1 is rewritten server); The url that browser also finds that there is partial page element points to other web proxy gateways (the domain name expansion servers in Fig. 1), so initiate the request to this page elements to other web proxy gateways.Like this, browser just can obtain described same domain name page elements from a plurality of web proxy gateways, has been equivalent to increase the domain name number that browser is accessed simultaneously, thereby has improved the concurrent download performance of browser.
