The search engine is a system for collecting information from the internet by using a specific computer program according to a certain policy and organizing and processing the collected information. After organizing and processing the information, the search engine provides retrieval service for the user and displays the relevant information retrieved by the user to a system used by the user, so that the user can conveniently and quickly locate the interested resources, and the target resources can be located by searching keywords. In addition, in the website of e-commerce and online ticket booking type, the query of resources by using a search engine is a core module of a service.

When accessing the target resource, when a user inputs a keyword in an input box, the script embedded in the page sends a request to the source station according to the keyword input by the user, so that the aim of prefetching the resource is fulfilled. However, due to the limitation of the front-end script, the pre-fetched keywords cannot be checked and corrected, for example, when the user wants to input the keyword "apple", but actually inputs the keyword "flat fruit", the pre-fetched resources are obtained through the actually input "flat fruit", and have a certain gap from the keyword "apple". For another example, the user wants to input the keyword "refrigerator", but actually inputs the keyword "bingxiang", and the prefetched resource is obtained through the actually input "bingxiang", so that the prefetched resource and the resource to which the user needs to respond have a certain difference, the accelerating effect on the dynamic page is not obvious, and the access speed to the target resource is low.

On the other hand, the existing dynamic access request has certain problems, for example, if the time for the source station database to respond to the request is long or the network condition is poor, the corresponding resource loading time is easily long, the access speed to the target resource is low, the normal operation of the website service is affected, the website income is reduced, and the user experience is reduced.

It should be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the application described herein may be used. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The embodiment of the invention provides a method for accessing a target resource on one side of a dynamic identification system.

Fig. 1 is a flowchart of a method for accessing a target resource according to an embodiment of the present invention. As shown in fig. 1, the access method of the target resource includes the following steps:

step S102, in the content distribution network, the dynamic identification system receives the first request forwarded by the node server.

In the technical solution provided in step S102 of the present invention, in a content distribution network, a dynamic identification system receives a first request forwarded by a node server, where the first request carries a first keyword used by a client to search for a resource through a first preset page.

A Content Distribution Network (CDN) is a layer of intelligent virtual Network on the internet basis formed by placing node servers throughout the Network. The CDN system can redirect the user request to the service node closest to the user in real time according to the network flow, the connection of each node, the load condition, the distance to the user, the response time and other comprehensive information, thereby quickly transmitting the website resources from the source station to the client, enabling the user to obtain the required content nearby and improving the access speed of the target resources. The content distribution network divides website content into static content and dynamic content through dynamic and static automatic separation. The static content can be the content displayed by pictures and the like, cannot be changed according to the difference of the permission, the type and the situation of a viewer, and cannot be changed within a long period of time. Dynamic content is the opposite of static content. Therefore, static content can be directly responded by the edge server in a distributed cache manner, and for dynamic content, a user needs to request corresponding resources from the source station through the CDN network and perform preloading.

A Dynamic Identification System (DIS) is a Dynamic access Identification System based on a content delivery network, and is deployed on a source-returning parent node of a CDN network to accelerate access to a target resource. The dynamic identification system receives a first request sent by a client forwarded by a node server, and the first request can be received through a system interface, wherein the node server can be a CDN network edge node, the first request carries a first keyword, the first keyword is used for the client to search resources through a first preset page, for example, a user inputs the first keyword in an input box through the client, a preset script embedded in a website page can generate a first request carrying the first keyword aiming at the first keyword, the first request is sent to the node server, and the dynamic identification system receives the first request forwarded by the node server. Optionally, the dynamic identification system receives a plurality of first requests forwarded by a plurality of node servers.

The first keyword is a pre-fetched keyword, that is, the first keyword is an original keyword actually displayed on the client, and may not be a keyword that the user really wants to input, for example, when the user wants to input the keyword "apple", but actually inputs the first keyword "flat fruit", and for example, the user wants to input the keyword "refrigerator", but actually inputs the first keyword "bingxiang".

And step S104, the dynamic identification system responds to the first request and processes the first keyword according to a preset rule to obtain a second keyword.

In the technical solution provided in step S104 of the present invention, the dynamic identification system responds to the first request, and processes the first keyword according to a preset rule to obtain the second keyword.

After the dynamic identification system receives the first request forwarded by the node server, the dynamic identification system responds to the first request, processes the first keyword according to a preset rule, and can process the first keyword through a preset system in the dynamic identification system, so that the first keyword is verified and corrected. For example, the hotword matching system performs hotword matching on a first keyword according to a hotword matching rule, and the fuzzy matching system performs module matching on the first keyword according to a fuzzy matching rule, so that the first keyword is processed into a second keyword capable of searching a target resource, wherein the second keyword is a keyword which a user actually wants to input in order to obtain the target resource, and the target resource comprises a picture resource. For example, a dynamic identification system receives a first request carrying a first keyword "flat fruit" forwarded by a node server, the dynamic identification system responds to the first request and processes the first keyword "flat fruit" according to a preset rule to obtain a second keyword "apple", and the second keyword "apple" is a keyword actually desired to be input by a user through a client; for another example, the dynamic identification system receives a first request carrying a first keyword "bingxiang" forwarded by the node server, the dynamic identification system responds to the first request, and processes the first keyword "bingxiang" according to a preset rule to obtain a second keyword "refrigerator", which is a keyword actually desired to be input by the user through the client, so that the dynamic identification system checks and corrects the pre-fetched keyword, and the first keyword is prevented from being directly sent to the source station server to access the resource with the gap from the target resource.

And step S106, the dynamic identification system sends a second request carrying a second keyword to the source station server.

In the technical solution provided in step S106 of the present invention, the dynamic identification system sends a second request carrying a second keyword to the source station server, where the source station server is configured to respond to the second request and send the target resource to the client according to the second keyword, and the client is configured to preload the target resource.

And after the dynamic identification system responds to the first request and processes the first keyword according to a preset rule to obtain a second keyword, the dynamic identification system generates a second request according to the second keyword and sends the second request to the source station server. And after receiving the second request, the source station server responds to the second request, and acquires a target resource according to a second keyword carried by the second request, wherein the target resource can be a dynamic page, that is, a response page obtained by responding to the second request by the source station server sends the target resource to the client, and the client preloads the target resource after receiving the target resource.

Optionally, the dynamic identification system receives the target resource sent by the source station, forwards the target resource to the client, and the client preloads the target resource after receiving the target resource, so as to improve the access speed of the target resource.

After receiving a search request for a target resource, a client can directly obtain the target resource from an edge node or a local node of the CDN, so that the loading time of the resource to be accessed by a user is shortened, the efficiency of target resource access is improved, and the user experience is further improved.

In the embodiment, a dynamic identification system receives a first request forwarded by a node server in a content distribution network, wherein the first request carries a first keyword used by a client for searching resources through a first preset page; the dynamic identification system responds to the first request and processes the first keyword according to a preset rule to obtain a second keyword; the dynamic identification system sends a second request carrying a second keyword to the source station server, wherein the source station server is used for responding to the second request and sending a target resource to the client according to the second keyword, the client is used for preloading the target resource, and the dynamic identification system receives the first request forwarded by the node server, responds to the first request, processes the first keyword according to a preset rule to obtain the second keyword, sends the second keyword back to the source station server, and returns the target resource to be preloaded by the source station server, so that the problem that the difference between the pre-fetched resource and the resource required by a user is large due to the fact that the keyword is not processed is solved, the problem of low access speed of the target resource is solved, and the effect of improving the access speed of the target resource is achieved.

As an optional implementation manner, the first request is generated by a preset script added to a first preset page, and before the dynamic identification system receives the first request sent by the node server, the dynamic identification system receives a third request which is sent by the client and carries a second preset page, where the second preset page is a page which is used by the client for searching for a target resource and to which the preset script is not added; the dynamic identification system responds to the third request and judges whether the second preset page meets the preset rule or not; if the dynamic identification system judges that the second preset page accords with the preset rule, the preset script is added to the second preset page to obtain a first preset page; the dynamic identification system sends a first preset page to the client through the node server.

Optionally, the preset script can also analyze the resources embedded in the page, for example, the image resources embedded in the page are analyzed to obtain a Uniform Resource locator (Uniform Resource L oscillator, abbreviated as UR L) of the image resources, wherein the first preset page can be a website page, the preset script can be a javascript script (JS script), before the dynamic identification system receives the first request sent by the node server, the dynamic identification system receives a third request carrying a second preset page sent by the client, the third request is a page request initiated by the client, the second preset page is a page request used by the client for searching a target Resource and not added with the preset script, the HTM L page responded by the source station server can be determined through a domain name accessed by the client, the dynamic identification system responds to the third request, judges whether the second preset page script conforms to the preset page script used for searching the target Resource and does not add the preset page script to the preset source server, and judges whether the second page meets the preset event and the preset page, if the preset page is not met with the preset event, the preset page is obtained by the dynamic identification system, and the second page is obtained by adding the preset event to the preset page to the preset source server, and the preset page.

As an optional implementation manner, before the dynamic identification system adds the preset script to the second preset page to obtain the first preset page, the dynamic identification system receives a page chain which is sent by the source station server and meets the preset rule, wherein the page chain comprises the first preset page; and dynamically identifying a system memory page chain to a preset memory position.

Before the dynamic identification system adds the preset script to the second preset page to obtain the first preset page, establishing an adding rule for the page needing to be added with the preset script. And the dynamic identification system receives a page chain which is sent by the source station server and needs to be added with a preset script, wherein the page chain comprises the second preset page and is a page with a searching function. After the dynamic identification system receives the page chain, the page chain is stored to a preset storage position, for example, the page chain is stored to a system database as an adding rule of a page needing to be added with a preset script, so that the rule of adding the preset script to the page is established, the preset script is added to a second preset page, and the purpose of monitoring and capturing the event of the first keyword according to the preset script is achieved.

As an optional implementation manner, the dynamic recognition system responds to the first request, and processes the first keyword according to a preset rule to obtain the second keyword, including: and the dynamic identification system responds to the first request and processes the first keyword according to the keyword popularity and/or the fuzzy search rule to obtain a second keyword.

The first keyword carried by the first request may not be a keyword which is used for searching the target resource and is input by the user, and the dynamic identification system processes the first keyword according to a preset rule after receiving the first request forwarded by the node server to obtain a second keyword so as to verify and correct the first keyword. The preset rules comprise keyword popularity rules and fuzzy search rules. The keyword popularity rule can be a rule for processing the first keyword according to the number of times the keyword is searched, and the fuzzy search is a rule for automatically performing fuzzy search according to synonyms of the first keyword so as to obtain more search results. The dynamic identification system responds to the first request, processes the first keyword according to the keyword popularity and/or the fuzzy search rule to obtain the second keyword, so that the purpose that the dynamic identification system responds to the first request, processes the first keyword according to the preset rule to obtain the second keyword is achieved, the purpose of checking and correcting the first keyword is achieved, the situation that the difference between the pre-fetched resource and the resource required by the user is large is avoided, and the access efficiency of the target resource is improved.

As an optional implementation manner, after the dynamic identification system sends the second request carrying the second keyword to the source station server, the dynamic identification system forwards the source station server to the client to respond to the second request, and obtains the target resource according to the second keyword.

After the dynamic identification system sends a second request carrying a second keyword to the source station server, the source station server responds to the second request and sends the target resource to the dynamic identification system according to the second keyword, the dynamic identification system sends the target resource to the client, and the client preloads the target resource, so that the access speed of the target resource is increased.

The node server searches whether a target resource is cached after receiving the resource request, if the target resource is cached, the target resource is directly sent to the client, if the target resource is not cached or the cached target resource is overdue, the target resource is requested from the source station server, the source station server responds to the request to send the target resource to the client, and after the client acquires the target resource, the target resource is cached locally to wait for the next access to the target resource, so that the access speed of the target resource is improved.

Optionally, after the user clicks the search button through the client, the browser initiates a dynamic request to the source station server through the CDN network to obtain a response page generated by the source station server, and the browser parses the response page and loads the target resource, and if the target resource is already stored locally, the target resource is directly loaded, so that the access speed to the target resource is increased; otherwise, the resources are requested and loaded through the CDN network until the page rendering is finished, so that the access efficiency of the target resources is improved.

The embodiment of the invention also provides an access method of the target resource from the client side.

FIG. 2 is a flow chart of another method for accessing a target resource according to an embodiment of the invention. As shown in fig. 2, the access method of the target resource includes the following steps:

step S202, in the content distribution network, the client is used for obtaining a first keyword for searching resources through a first preset page.

In the technical solution provided by step S202 of the present invention, in the content distribution network, the client is configured to obtain a first keyword for searching for a resource through a first preset page.

The CDN system can redirect the user's request to the service node closest to the user in real time according to the network flow and the comprehensive information such as the connection of each node, the load condition, the distance to the user, the response time and the like, thereby quickly transmitting the website resources from a source station to a client, enabling the user to obtain the required content nearby and improving the access speed to the target resources. The content distribution network divides website content into static content and dynamic content through dynamic and static automatic separation. The static content can be directly responded by the edge server in a distributed cache mode, and for the dynamic content, a user needs to request corresponding resources from the source station through a CDN (content delivery network) and perform preloading.

The client is used for acquiring a first keyword for searching resources through a first preset page, for example, a user inputs the first keyword in an input box through the client, a preset script embedded in a website page generates a first request carrying the first keyword aiming at the first keyword, and the first request is sent to the node server. The client may be a browser.

Step S204, the client is used for sending a first request carrying a first keyword to the dynamic identification system through the node server.

In the technical solution provided in step S204 of the present invention, the client is configured to send a first request carrying a first keyword to the dynamic identification system through the node server.

The dynamic access identification system is based on a content delivery network, is deployed on a source returning father node of the CDN, and is used for accelerating the access of target resources. After the client is used for acquiring a first keyword for searching resources through a first preset page, the client generates a first request according to the first keyword and sends the first request to a dynamic identification system through a node server, and the dynamic identification system can receive the first keyword through a system interface. Alternatively, the node server may be a CDN network edge node.

The dynamic identification system responds to the first request, processes the first keyword according to a preset rule, and can process the first keyword through a preset system in the dynamic identification system, so that the first keyword is verified and corrected. For example, the hotword matching system performs hotword matching on a first keyword according to a hotword matching rule, and the fuzzy matching system performs module matching on the first keyword according to a fuzzy matching rule, so that the first keyword is processed into a second keyword capable of searching a target resource, and the second keyword is a keyword which a user actually wants to input in order to obtain the target resource, so that the pre-fetched keyword is verified and corrected by the dynamic identification system, and the condition that the first keyword is directly sent to the source station server to access a resource with a gap with the target resource is avoided.

And step S206, the client receives the target resource sent by the source station server according to the second keyword by responding to the second request.

In the technical solution provided in step S206 of the present invention, the client receives the target resource sent by the source station server by responding to the second request and according to the second keyword, where the second request carries the second keyword obtained by the dynamic identification system by responding to the first request and processing the first keyword according to the preset rule.

After the client is used for sending a first request carrying a first keyword to the dynamic identification system through the node server, the dynamic identification system responds to the first request and processes the first keyword according to a preset rule to obtain a second keyword, and then the dynamic identification system generates a second request according to the second keyword and sends the second request to the source station server. After receiving the second request, the source station server responds to the second request, and obtains a target resource according to a second keyword carried in the second request, where the target resource may be a dynamic page, that is, a response page obtained by the source station server responding to the second request, and the client receives the target resource sent by the source station server according to the second keyword by responding to the second request.

Step S208, the client pre-loads the target resource.

In the technical solution provided by step S208 of the present invention, the client pre-loads the target resource.

And after the client receives the target resource sent by the source station server by responding to the second request and according to the second keyword, the client pre-loads the target resource. The client receives the search operation submitted by the user, and can acquire the target resource from the edge node or the local of the CDN, so that the loading time of the target resource required by the user is shortened, the access speed of the target resource is increased, and the user experience is finally improved.

The technical solution of the present invention will be described below with reference to preferred embodiments.

The embodiment of the invention is a network architecture based on a content distribution network, aims to solve the problem that the waiting time for loading resources is long when a user searches through keywords, and improves the user experience and indirectly improves the website income by reducing the loading time for the user to wait for pages. The embodiment of the invention mainly improves the existing CDN dynamic acceleration network from the following two aspects:

the JS script is embedded in the website page to realize event monitoring and capturing of the keywords input by the user in the browser.

And constructing a dynamic identification system in the CDN, wherein the dynamic identification system is based on a content delivery network, the dynamic identification system can process the keywords captured by the script according to a certain processing rule, the processed keywords are sent to a source station server, the source station server sends target resources according to the processed keywords, and the client receives the target resources and preloads the target resources. The system can intelligently analyze target resources in a user page through the script, for example, elements such as static pictures and the like are analyzed, the target resources are pre-fetched before the user accesses the page, and the loading time of the user accessing a website is shortened through the pre-loading of the client to the target resources.

FIG. 3 is a schematic diagram of a target resource access system according to an embodiment of the invention. As shown in fig. 3, the target resource access system includes: the system comprises a source station server, a dynamic identification system, a node server and a client.

After the JS script is added to the page, when a client accesses the webpage, event monitoring and capturing of key words input by a user in a browser are realized through the JS script embedded in the page.

The dynamic identification system is deployed on a source returning father node of the CDN, can receive a request of a CDN edge node, and returns a source request to a source station server to obtain a target resource. After receiving a request sent by a CDN network edge node, the dynamic identification system processes a keyword carried by the request sent by the CDN network edge node according to a keyword popularity rule and/or a fuzzy search rule, and sends the request carrying the processed keyword to a source station server.

The client receives the target resource returned by the source station server, and the client may include a plurality of clients, such as client a and client B. The client preloads the target resource. After a user submits a search request through a client, a target resource can be directly obtained from an edge node or the local of the CDN, optionally, the target resource is a picture resource, so that the loading time required for accessing the target resource is shortened, the efficiency of request response is improved, and the user experience is finally improved.

FIG. 4 is a flow diagram of another method for accessing a target resource in accordance with an embodiment of the present invention. As shown in fig. 4, the access method of the target resource includes the following steps:

in step S401, the client receives a keyword.

The user initiates a page request through the client, the dynamic identification system embeds the JS script into an HTM L page responded by the source station and then issues the JS script to the edge node server, and the edge node server sends the HTM L page embedded with the JS script to the client.

And step S402, the client is used for monitoring the keyword through the JS script and sending a request carrying the keyword to the dynamic identification system.

After the client receives the HTM L page embedded with the JS script, the JS script monitors the input box in real time, when the user inputs the keyword through the input box, the JS script captures the content of the keyword input by the user, and a request carrying the keyword is sent to the dynamic identification system through an edge node server of the CDN.

Step S403, the dynamic identification system processes the keywords carried by the request and sends the processed keywords to the source station server, and the source station server sends the response page to the client according to the processed keywords.

The dynamic identification system receives keywords forwarded by the edge node server, re-generates source return keywords through real-time heat matching and fuzzy matching rules, sends a request carrying the source return keywords to the source station server, the source station server receives the request carrying the source return keywords and sends a response page to the client, and the source station server can send the response page through the dynamic identification system.

Step S404, the client is used to parse UR L of the resource in the response page through the script.

After receiving the response page, the client may parse the UR L of the resource in the response page through the script, and may parse the UR L of the corresponding picture resource in the HTM L page.

In step S405, the client receives an instruction for searching for a keyword.

After the client receives the keyword, a search instruction for searching the keyword is received through the input box.

Step S406, the client performs a dynamic request, and sends a source return request to the source station server through the CDN network.

And the client side carries out dynamic request according to the search instruction and sends a source return request to the source station server through the CDN.

Step S407, the source station server generates a response page according to the back-to-source request, and sends the response page to the client through the CDN network.

In step S408, the client parses the UR L of the response page.

In step S409, the client determines whether or not to cache UR L.

After step S404 and step S408, the client determines whether to cache UR L, if the client determines that UR L is cached, step S412 is performed, and if the client determines that UR L is not cached, step S410 is performed.

Step S410, the client sends a request for obtaining the target resource to the CDN network node server.

And if the client does not have the UR L cache, sending a request for obtaining the target resource to an edge node server of the CDN network.

Step S411, the network node server directly responds to the resource or requests the target resource back according to the caching condition of the target resource.

The network node server searches whether the target resource is cached in the network node server. If the node server caches the target resource, the target resource is directly sent to the client; and if the network node server does not cache the target resource, sending a request for acquiring the target resource to the source station server, and responding to the request by the source station server to send the target resource to the client.

Step S412, the client loads the target resource.

The client analyzes, loads and renders the received target resource, so that the access speed of the target resource is improved.

As for the above-mentioned steps S405 to S408, which are processes of dynamic response after the client receives the keyword, steps S402 to S404 are processes of static response after the client receives the keyword. Steps S405 to S408 may be performed after steps S402 to S404.

FIG. 5 is a diagram illustrating a process of a dynamic access recognition system according to an embodiment of the present invention. As shown in fig. 5, the dynamic identification system is deployed on a source return father node of the CDN network, has an independent database, and can perform logical judgment and operation by a page for a request of an edge node server and a response of a source station server. And the source station server sends the page chain to which the JS script needs to be added to the dynamic identification system as a pre-stored addition rule. When a JS script is added to a page of a client through a system interface of a dynamic identification system, the client is used for capturing a keyword through the JS script and forwarding the keyword to the system interface of the dynamic identification system through an edge node of a CDN network, the dynamic identification system processes the keyword, the keyword can be processed according to a hot word matching rule according to a hot word matching system, the keyword can be processed according to a fuzzy matching rule through the fuzzy matching system to obtain the processed keyword, a request carrying the processed keyword is sent to a source station, the source station responds to the request carrying the processed keyword, and a response page is sent to the client.

FIG. 6 is a flow chart of another method for accessing a target resource according to an embodiment of the invention. As shown in fig. 6, the access method of the target resource includes the following steps:

in step S601, the client acquires the page W to which the script is added.

When a user A accesses a page W with a search frame in a domain name X, a dynamic identification system adds a script into the page W and sends the page W with the script added to the user according to rules negotiated with a source station (the source station gives a series of page chains with a search function, and the dynamic identification system stores the rules into a system database of the dynamic identification system), and when the dynamic identification system finds that the page W accords with the addition rules, the client receives the page W with the script added.

In step S602, the client receives a first keyword input by the user through the input box.

The user a may input a first keyword "flat fruit" in the search box, the client receives the first keyword "flat fruit", the first keyword "flat fruit" is not a keyword that the user a wants to input, and the resource loaded by the first keyword "flat fruit" is not a target resource that the user really wants to obtain.

Step S603, capturing the first keyword by the script of the page of the client and sending the first keyword to the dynamic identification system.

Capturing a first keyword by a script of a page of a client, when capturing the first keyword 'pingguo' input by a user, sending a request carrying the first keyword 'pingguo' to an edge node of the CDN, identifying the request carrying the first keyword 'pingguo' as a pre-query request by the edge node of the CDN, and sending the request to a dynamic identification system

Step S604, the dynamic identification system processes the keyword to obtain a second keyword.

The dynamic identification system processes the keywords in the received request, and the keywords can be processed by a hot word matching system and a fuzzy matching system to obtain a second keyword, for example, the first keyword "flat fruit" is corrected to be the second keyword "apple", the second keyword "apple" is the keyword that the user wants to input, and the target resource that the user really wants to obtain is loaded through the second keyword "apple".

Step S605, the dynamic identification system sends the second keyword to the source station server.

After the dynamic identification system processes the keywords to obtain second keywords, the dynamic identification system sends the second keywords to the source station server, and the dynamic identification system can send a dynamic request carrying the second keywords "apple" to the source station server.

Step S606, the source station server sends the page Y to the client according to the second keyword.

And the source station server receives the dynamic request, generates a dynamic page Y according to the second keyword, and sends the page Y to the dynamic identification system.

In step S607, the client is configured to perform resource pre-fetching on UR L of page Y through the script.

After the source station server sends the page Y to the client according to the second keyword, the client is configured to perform resource pre-fetching on the UR L of the page Y through the script, for example, the JS script analyzes the intra-page embedded picture resource to obtain the UR L address of the picture resource.

In step S608, the client receives a search instruction for the user to search for the first keyword through the search button.

After the client receives the first keyword input by the user through the input box. The client receives a search instruction of a user for searching the first keyword through a search button.

Step S609, the client acquires the page Z sent by the source station server according to the search instruction.

After the user a clicks the search button, the client initiates a dynamic request to the source station server through the CDN network according to the search instruction, and obtains a page Z generated by the source station in response to the dynamic request.

In step S610, the client determines whether the target resource is cached locally.

After step S607 and step SS609, the client determines whether the target resource in page Y or page Z is already cached locally. If the target resource is cached locally, step S611 is performed, and if the target resource is not cached locally, step S611 is performed. If the target resource is not cached locally, the client is configured to initiate a resource request through an edge node of the CDN network, so as to request the node server to obtain the target resource, and if the node server is cached in the target resource, perform step S611. Or under the condition that the node server does not cache the target resource, or under the condition that the node server caches the target resource but the target resource is expired, the node server requests the source station to acquire the target resource, the source station server sends the target resource to the client, and the client caches the requested target resource locally.

Step S611, the client loads and renders the target resource.

And under the condition that the client receives the target resource, the client loads and renders the target resource. Otherwise, the client is used for requesting and loading the target resource through the CDN network until the page rendering is finished, so that the access speed of the target resource is increased.
