In order to reduce the congestion of the backbone network, the resources accessed by the user can be downloaded and cached locally, so that the user can access the resource locally.

Currently, the Internet resource service system includes a Redirection Subsystem (RSS), a Statistical Analysis Subsystem (SAS), a Dispatching Subsystem (DSS), a Cache Subsystem (CSS), and Management Subsystem (MSS). The RSS is used to obtain an access request sent by the user to the Internet server, and the resource information carried by the access request is sent to the CSS via the SAS and the DSS, to notify the CSS to download and cache the resource to the source station of the resource, or to access the resource. The request is redirected to the CSS so that the user can request access to the resource from the CSS; the CSS is used to download and cache resources from the Internet; the MSS is used to manage the various subsystems. Based on the Internet resource service system, the resource access process specifically includes:

Each website on the Internet analyzes the resources of the website, finds out the resources that the website can cache, identifies them, then develops plug-ins for each website on the Internet and loads the plug-ins into RSS. When the user sends an access request to a resource of a certain website to the Internet server, the RSS obtains the access request, and calls the plug-in of each website to identify the resource. If the plug-in of the website identifies the resource, the access request is resolved. Get a unique identifier for the resource. Further, the RSS may send the unique identifier of the resource to the CSS via the SAS and the DSS to notify the CSS to download and cache the resource to the source station of the resource according to the unique identifier of the resource. When the user sends the access request to the Internet server again, after the RSS obtains the access request, the RSS analyzes the access request, and queries the resource to send a redirect message to the user after the CSS has been cached. The message carries the address of the CSS, so that the user can request the CSS to access the resource according to the address of the CSS, and the CSS returns the resource, thereby implementing access to the resource of the website.

Personnel analyze and obtain.

The process of obtaining the universal identification features of the multiple resource types will be described below by using the processes in step 401a and step 401b, respectively.

401a. For the universal identification feature X1 of the picture type, the acquisition process of the universal identification feature X1 may include steps 401a1 to 401a3:

401a1: Get format information of multiple picture samples.

For each picture sample, the format information of the picture sample is used to indicate the resource type and resource format of the picture sample. For example, the format information of the image sample may be image/jpg, where image indicates that the resource type of the image sample is a picture, and jpg indicates that the resource format of the image sample is a jpg format.

The format information of the plurality of picture samples may be obtained from the download record of the plurality of picture samples, and the format information of the picture sample is saved in the download record of each picture sample. The format information of the plurality of picture samples is counted, and the statistical results are as follows:

Link distribution dimension:

Static link 91%, dynamic link 9%

Traffic from the suffix and contontentype: 91%

Suffix distribution dimension:

Jpg, gif, png, jpeg suffixes account for about 85%

Format information distribution dimension:

Image/jpeg, image/png, image/gif, image/webp, image/jpg accounted for 98%

Format information:

It can be seen from the above statistical results that the proportion of the image samples in the plurality of image samples that are statically linked and dynamically linked is 91% and 9%, respectively, that is, the URLs of the plurality of image samples are almost static links. The picture resource is generally a cacheable static picture resource. Therefore, the picture resource can be identified according to the format information, that is, the format information of the picture resource can be determined as the identification feature of the picture resource.

401a2: For each picture sample, the format information of the picture sample is determined as an identification feature of the picture sample.

The format information of the picture resource may be determined as the identification feature of the picture resource in step 401a1. For each picture sample, the format information of the picture sample may be determined as the identification feature of the picture sample.

Through the step 401a2, the identification features of the plurality of picture samples can be obtained, as shown in the statistical result in step 401a1.

401a3: Determine, according to the identification feature of the plurality of picture samples, a universal recognition feature of the picture type, where the universal recognition feature of the picture type is an identification feature that is greater than a first specified ratio in the identification features of the plurality of picture samples.

The first specified ratio may be selected by the developer. For example, the first specified ratio may be 0.7%. According to the statistical result in step 401a1, the recognition features of the plurality of picture samples whose proportions are larger than the first specified ratio (0.7%) include image/jpeg, image/png, image/gif, image/webp, and image. /jpg, the proportion is 64.0588%, 16.9975%, 15.1025%, 2.31268% and 0.740895%. Therefore, the universal recognition feature X1 of the picture type may include: the format information is image/jpeg, image/png, image/gif, image/jpg, and image/webp.

In the related art, for the identification that the URL is a static link and contains a specific suffix (jpg, gif, png, and jpeg), the recognition rate is 85%, and in the embodiment of the present disclosure, the recognition of the universal recognition feature X1 for the picture type (identification image/ Jpeg, image/png, image/gif, image/webp, and image/jpg), the recognition rate can be increased to 98%.

401b. For the universal recognition feature X2 of the webpage text type, the universal recognition feature X3 of the download type, the universal recognition feature X4 of the audio type, and the universal recognition feature X5 of the video type, the acquisition process of the universal identification feature X2 to X5 may include steps 401b1 to 401b3:

401b1: For each resource type, obtain format information of a plurality of target samples of the resource type and a URL of the plurality of target samples.

The obtaining the format information of the plurality of target samples is the same as the step 401a1, and the URL of each target sample is a link corresponding to the access request of the target sample, and is carried by the access request of the target sample, so In the access request of the target samples, the URLs of the plurality of target samples are obtained.

(1) The resource type is the webpage text type, and the target sample is a webpage text sample as an example, and the format information of the text samples of the plurality of webpages is counted, and the statistical result is as follows:

Link distribution dimension:

Static link 57%, dynamic link 42%

Traffic identification: 34.6217%

Suffix distribution dimension:

Html, html, js, css static link traffic accounted for 20%

Format information distribution dimension:

Text/html, text/plain, text/javascript, text/css, text/xml account for 99% of the total traffic

It can be seen from the above statistical results that the proportions of the webpage text samples in which the URLs are statically linked and dynamically linked in the plurality of webpage text samples are 57% and 42%, respectively. It may be noted that there may be a dynamic link resource that cannot be directly cached in the webpage text resource. Therefore, in order to ensure the accuracy of the identification, the webpage text resource cannot be identified only according to the format information, but the webpage text resource needs to be identified by combining the format information and the URL. That is, the identification information of the webpage text resource can be determined by combining the format information and the URL.

(2) The resource type is the download type, and the target sample is a download sample as an example, and the format information of the plurality of downloaded samples is counted, and the statistical result is as follows:

Link distribution dimension:

Static link 51.1451%, dynamic link 48.8549%

Suffix distribution dimension:

Static link traffic for a specific download suffix is 27%

Format information distribution dimension:
