Referring to Fig. 2, the structure chart of child resource optimization module according to an embodiment of the invention is shown.Child resource optimizes Module 130 includes：Child resource size analyzes submodule 132 and child resource modification submodule 134.

Child resource size analyzes submodule 132, is suitable to the son money of the uncached webpage in judged result is cache module 120 During source, the child resource is cached in cache module 120 according to the size of the child resource of webpage in response message.

Child resource changes submodule 134, is suitable in judged result is cache module 120 child resource of cache web pages When, the response message for receiving is modified according to the child resource for having cached, client 200 is made by amended response message Obtain child resource.

In one embodiment, child resource size analyzes submodule 132 in the child resource according to webpage in response message Size determine cache the child resource after, record webpage URL with caching the child resource corresponding relation.

Child resource changes the corresponding relation of URL of the submodule 134 according to the webpage of record and the child resource of caching, modification The response message of reception.

Proxy module 110, is further adapted for for child resource modification 134 amended response message of submodule being sent to client 200。

Cache module 120, is suitable to the child resource included by cache web pages.

Referring to Fig. 3, the structure chart of child resource optimization module in accordance with another embodiment of the present invention is shown.Child resource is excellent Changing module 130 also includes de-redundancy submodule 136.De-redundancy submodule 136, is suitable to after it is determined that caching child resource, to the son Resource carries out de-redundancy, and the child resource after de-redundancy is cached in cache module 120.

For example, blank character in CSS child resources and Javascript child resources can be got rid of, it is also possible to will Annotate in CSS child resources and Javascript child resources and get rid of.Thereby, it is possible in CSS child resources and Javascript moneys In the case that source is lossless, reaches and CSS child resources and Javascript child resources are optimized, save webpage flow, to webpage Access the effect for accelerating.

In one embodiment, the child resource for including inside the html pages in the response message returned by website When size is excessive, the inside child resource is converted to into outside child resource.

In the present embodiment, client 200 is carried out the request sent by web page access and is transmitted to the net by proxy module 110 The response message that website returns is transmitted to the client 200 by the website belonging to page.

The inside child resource of the webpage that child resource size analysis submodule 132 is included in judging the response message that website returns Size whether be more than or equal to the first pre-set threshold value, if it is, extract the inside child resource being delayed in cache module 120 Deposit.

The inside child resource for having cached in the response message that proxy module 110 is received by child resource modification submodule 134 Content modification is links corresponding with the inside child resource of caching.

Amended response message is sent to client 200 by proxy module 110, receives the son money that client 200 sends Source is asked, according to the inside child resource that being linked in cache module 120 in the child resource request searches caching, by what is found Internal child resource returns to client 200.

For example, when client 200 accesses webpage first, client 200 is carried out web page access by proxy module 110 The request for being sent is transmitted to the website belonging to the webpage, and the response message that website returns is transmitted to the client 200.This Outward, after proxy module 110 receives the response message of website return, child resource size analysis submodule 132 judges that website returns Response message in CSS child resources inside the webpage that includes size whether more than or equal to pre-set threshold value CSSOutlineMinBytes, if it is, extract the CSS child resources being cached in cache module 120.Or, agency After module 110 receives the response message of website return, child resource size analysis submodule 132 judges the response letter that website returns Whether the size of the JavaScript child resources inside the webpage included in breath is more than or equal to pre-set threshold value JsOutlineMinBytes, if it is, extracting the JavaScript child resources, is cached in cache module 120. Above-mentioned process can be made to CSS child resources and JavaScript child resources simultaneously.

When client 200 accesses webpage again, client 200 is carried out what web page access was sent by proxy module 110 Request is transmitted to the website belonging to the webpage, after receiving the response message of website return, indicates child resource modification submodule 134 Modification response message.Child resource change submodule 134 by the CSS child resources for having cached in response message and/or Javascript child resource content modifications are the chain corresponding with the CSS child resources and/or Javascript child resources of caching Connect.Amended response message is sent to client 200 by proxy module 110, and the child resource for receiving the transmission of client 200 please Ask, according to CSS child resources and/or Javascript that being linked in cache module 120 in the child resource request searches caching The CSS child resources for finding and/or Javascript child resources are returned to client 200 by child resource.

So, by above-described embodiment, solve the child resource included inside the webpage size it is excessive when, download webpage The probability retransmitted after data transmission fails during primary resource increases, the problem that transmission cost increases.Therefore, it is possible to obtain in sub- money In the case that the application effect in source is not damaged, increase webpage access speed, reduce server back end website pressure it is beneficial Effect.

In one embodiment, when the html pages in the response message returned by website outside child resource size When too small, the outside child resource is converted to into internal child resource.

The outside child resource of the webpage that child resource size analysis submodule 132 is included in judging the response message that website returns Size whether be less than or equal to the second pre-set threshold value, if it is, the outside child resource is cached in cache module 120.

With the outside child resource for caching in the response message that proxy module 110 is received by child resource modification submodule 134 Corresponding link is revised as the outside child resource content for having cached.

Amended response message is sent to client 200 by proxy module 110.

For example, when client 200 accesses webpage first, the proxy module 110 of server 100 is by client 200 Carry out the request sent by web page access and be transmitted to the website belonging to the webpage, receive the response message that website returns, judge Do not have to cache the child resource in the response message in the cache module 120 of server 100, the response message forwarding that website is returned Give the client 200.Client 200 parses the link of outside child resource from response message, by the son money including the link Source request is sent to server 100, and the proxy module 110 of server 100 forwards a request to website, and website is returned comprising outside The corresponding information is returned to client 200 by the response message of child resource content, proxy module 110.Additionally, proxy module 110 After receiving the response message of website return, the child resource size analysis submodule 132 in child resource optimization module 130 judges net Whether the size of the CSS child resources outside webpage included in the response message for returning of standing is less than or equal to pre-set threshold value CSSInlineMaxBytes, if it is, extract the CSS child resources being cached in cache module 120.Or, Dai Limo After block 110 receives the response message of website return, child resource size analysis submodule 132 judges the response message that website returns In JavaScript child resources outside the webpage that includes size whether less than or equal to pre-set threshold value JsInlineMaxBytes, If it is, extract the JavaScript child resources being cached in cache module 120.Can also be simultaneously to CSS child resources Make above-mentioned process with JavaScript child resources.

When client 200 accesses webpage again, client 200 is carried out webpage visit by the proxy module 110 of server 100 Ask that sent request is transmitted to the website belonging to the webpage, after receiving the response message of website return, child resource optimization mould The child resource modification modification response message of submodule 134 in block 130.Child resource change submodule 134 by response message with The link that the CSS child resources and/or Javascript child resources of the outside of caching are corresponding is revised as the outside for having cached The content of CSS child resources and/or Javascript child resources.Amended response message is sent to client by proxy module 110 End 200.Thus, client 200 directly obtains CSS child resources from the response message after receiving the amended response message And/or Javascript child resources.

So, by above-described embodiment, solve outside child resource when webpage size it is too small when, be which sets up TCP The cost of connection is excessive with respect to for its data transfer so that the problem of the inefficiency of transmission data.Therefore, it is possible to obtain In the case that the application effect of child resource is not damaged, increase webpage access speed, reduce the website pressure of server back end Beneficial effect.

URL is accessed as http with client below:As a example by the webpage of //www.a.com, the server of the present invention is carried out Illustrate.

Step S710, the request of the access webpage that client is sent by server are transmitted to the website belonging to webpage, receive The response message that website returns.

Whether step S720, server judge in the server child resource of cache web pages, if in the server not The child resource of cache web pages, then execution step S730, if the child resource of cache web pages, execution step in server S770。

The response message that website returns is transmitted to client by step S730, server.

Step S740, the size of the inside child resource of webpage that server is included in judging the response message that website returns is It is no to be more than or equal to the first pre-set threshold value, if it is, execution step S750, otherwise, execution step S760.

Step S750, server are extracted the inside child resource and are cached.

Step S760, server are not cached to response message inside child resource.

Step S770, server by the inside child resource content modification for having cached in response message be with caching this is interior Amended response message is sent to client by the corresponding link of portion's child resource.

Step S780, server receive the child resource request that client sends, according to being linked in the child resource request The inside child resource of caching is searched in server, the inside child resource for finding is returned to into client.

For example, when client accesses webpage first, server by client carry out that web page access sent please Ask and be transmitted to website belonging to the webpage, the response message that website returns is transmitted to into the client.Additionally, server is received After the response message that website returns, the size of the CSS child resources inside webpage included in judging the response message that website returns Whether pre-set threshold value CSSOutlineMinBytes is more than or equal to, if it is, extract the CSS child resources carrying out in the server Caching.Or, whether the size of the JavaScript child resources inside webpage included in judging the response message that website returns More than or equal to pre-set threshold value JsOutlineMinBytes, if it is, the JavaScript child resources are extracted, in the server Cached.Above-mentioned process can also be made to CSS child resources and JavaScript child resources simultaneously.

When client accesses webpage again, client is carried out the request sent by web page access and is transmitted to this by server Website belonging to webpage, after receiving the response message of website return, judge to be cached with the CSS child resources and/or Javascript child resources, then repair the CSS child resources for having cached and/or Javascript child resource contents in response message It is changed to the CSS child resources with caching and/or Javascript child resources is corresponding links.Server is by amended response Information is sent to client, receives the child resource request that client sends, according to being linked at server in child resource request The middle CSS child resources and/or Javascript child resources for searching caching, by the CSS child resources for finding and/or Javascript Child resource returns to client.

Show referring to Fig. 8 and according to an embodiment of the invention outside child resource in webpage is converted to into internal child resource Method flow chart.The method comprises the steps.

Step S810, the request of the access webpage that client is sent by server are transmitted to the website belonging to webpage, receive The response message that website returns.

Whether step S820, server judge in the server child resource of cache web pages, if in the server not The child resource of cache web pages, then execution step S830, if the child resource of cache web pages, execution step in server S870。

The response message that website returns is transmitted to client by step S830, server.

Step S840, the size of the outside child resource of webpage that server is included in judging the response message that website returns is It is no to be less than or equal to the second pre-set threshold value, if it is, execution step S850, otherwise, execution step S860.

Step S850, server are extracted the outside child resource and are cached.

Step S860, server are not cached to outside child resource in response message.

Step S870, server will be revised as delaying with corresponding the linking of outside child resource for caching in response message Amended response message is sent to client by the outside child resource content deposited.

For example, when client accesses webpage first, server by client carry out that web page access sent please Ask and be transmitted to website belonging to the webpage.Server receives the response message that website returns, and judges no caching in server The response message that website returns is transmitted to the client by the child resource in the response message.Client is solved from response message The link of outside child resource is separated out, the child resource request including the link is sent to into server, server is forwarded a request to Website, website return the response message comprising outside child resource content, and the corresponding information is returned to client by server.This Outward, after server receives the response message of website return, CSS outside webpage included in the response message that website returns Whether the size of resource is less than or equal to pre-set threshold value CSSInlineMaxBytes, if it is, extracting the CSS child resources in clothes Cached in business device.Or, after server receives the response message of website return, in judging the response message that website returns Comprising webpage outside the size of JavaScript child resources whether be less than or equal to pre-set threshold value JsInlineMaxBytes, such as Fruit is then to extract the JavaScript child resources to be cached in the server.Can also simultaneously to CSS child resources and JavaScript child resources make above-mentioned process.

When client accesses webpage again, client is carried out the request sent by web page access and is transmitted to this by server Website belonging to webpage, receives the response message of website return.Server by response message with the CSS of outside for caching The corresponding link of child resource and/or Javascript child resources be revised as the CSS child resources of the outside for having cached and/or The content of Javascript child resources.Amended response message is sent to client by server.Thus, client is received After the amended response message, CSS child resources and/or Javascript child resources are directly obtained from the response message.
