Description

Method and device for accelerating website access

technical field

The present application relates to the field of Internet technologies, in particular to a method and device for accelerating website access.

Background technique

In the Internet age, how to improve the website access rate is the primary issue to improve the user's online experience. The process from the user’s access request to the website’s return of content resources to the user is affected by many factors, including both the user’s side and the website’s own factors, as well as factors in the communication link between the two sides. On the one hand, various website access acceleration technologies have also been produced.

The interconnection bottleneck between different logical networks is an important factor affecting the network connection rate. Taking the domestic network environment as an example, there are multiple logical networks such as China Telecom, China Unicom, Railcom, and Education Network, which are affected by objective conditions. The internal communication is very smooth, but once it involves the interconnection between networks, there will be various situations such as excessive delay, packet loss or even failure to connect. To solve this problem, the existing technical solution is to build a proxy server with multi-line bandwidth, as shown in Figure 1, the user equipment and the website server are located in different logical networks A and B, if the user directly accesses the website, the rate will be affected The impact of A and B network interconnection bottlenecks. After the proxy server is set up, the interaction between the user device and the website server can be forwarded through the proxy server. Since the proxy server has the dual-line bandwidth of both network A and network B, it can accelerate the process of users accessing the website.

The problem with the above solution is that it has poor versatility. It only has an acceleration effect for scenarios where there is a network interconnection bottleneck between the user device and the website server. For the case where the connection bottleneck does not lie in the network interconnection, it cannot accelerate the effect, and may even cause additional Forwarding delay, proxy server hardware resources are not fully utilized.

detailed description

In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described in detail below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only It is a part of the embodiments of this application, not all of them. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in this application shall fall within the protection scope of this application.

The existing proxy server acceleration technology is to achieve the effect of Internet access acceleration from the perspective of improving the network connection bandwidth or connection quality. If the bottleneck of the Internet access rate does not lie in the network connection, for example: the user device and the website server are located on the same logical network, or in the Different logical networks with relatively smooth connections, or the rate at which user equipment and website accelerators can access the network are limited. In these cases, the existing technology cannot effectively achieve the acceleration effect.

Aiming at the problems existing in the prior art, the present application realizes the acceleration effect of surfing the Internet from the perspective of improving communication efficiency. Through the research, it is found that the delay overhead of the process from the user sending the access request to the website returning the content resource to the user is mainly reflected in the following aspects:

1) The user device and the website server need to establish HTTP connections multiple times to obtain different HTTP resources;

2) When the user side accesses the website based on the domain name, the delay caused by domain name resolution;

3) Downlink transmission of website resources;

This application provides corresponding Internet access acceleration solutions for the above aspects, and the corresponding system architecture is shown in Figure 2:

The website server 30 is the owner of the resources;

The user device 10 is a resource demander, and uses the website domain name to initiate a resource access request to the website server 30;

The proxy server 20 is logically located between the user equipment 10 and the website server 30, and the communication connection can be realized through various forms of networks between the proxy server 20 and the user equipment 10, the proxy server 20 and the website server 30, and the proxy server 20 can Communicate with multiple different user devices and multiple different web servers respectively.

According to the solution of the present application, the proxy server 20 can intercept the resource access request initiated by any user device 10 to any website server 30, and accelerate the subsequent access process based on the request.

When the network communication adopts the TCP protocol, the connection modes of the communication parties can be divided into two types: long connection and short connection. The so-called long connection means that multiple data packets can be sent continuously on a TCP connection. During the maintenance period of the TCP connection, if no data packets are sent, both parties need to send detection packets to maintain the connection. A short connection means that when the communication parties have data interaction, a TCP connection is established, and after the data transmission is completed, the TCP connection is disconnected.

The HTTP protocol is a typical application of the TCP protocol, and it is also the most widely used protocol on the Internet. Many websites use HTTP connections when providing services to users. The HTTP connection is a short connection. Each request sent by the user device requires the server to send back a response. After the request ends, the connection will be released actively. The purpose of this is to avoid a large number of concurrent connections caused by a large number of users visiting the website, thereby reducing the resource consumption of the website server. But from another perspective, since various resources on the website page, such as pictures, audio, video, etc., are provided in the form of HTTP links, each time the user device requests a resource, it needs to establish an HTTP connection with the website server. , the server needs to wait until the connection is successfully established before it can feed back resources to the user device. This method of frequently establishing HTTP connections will inevitably increase the interaction delay between the user device and the website server.

From the perspective of third-party acceleration, it is impossible to change the connection strategy of the website itself, but under the proxy server acceleration mechanism, the user device actually establishes a connection with the proxy server and obtains resources from the proxy server. Connections between servers to reduce connection overhead.

As shown in Fig. 3, it is a flow chart of the method for accelerating website access provided by the present application. The method is based on a proxy server and may include the following steps:

S101, obtaining an access request for a target website resource sent by a user device;

S102. Confirm that a Socket connection has been established between the user equipment and the proxy server;

S103. Obtain the target website resource according to the access request;

S104, using the Socket connection to feed back the acquired target website resources to the user equipment.

Compared with the existing proxy acceleration scheme, this application replaces the default HTTP connection mode between the user equipment and the proxy server with the Socket connection mode. Compared with the HTTP connection, the Socket connection is a long connection, that is, unless both parties actively required, otherwise the connection will not be disconnected automatically after it is established. Using this feature, the proxy server can transfer the content that originally needs to be transmitted through multiple HTTP connections through one Socket connection, thereby avoiding the extra delay caused by frequent establishment of HTTP connections.

The application premise of this application scheme is that the proxy server needs to be able to intercept the resource access request initiated by the user device to the website server. At the practical application level, many products have such conditions, such as browsers, search engines, website navigation, public platforms, Comprehensive business service window, etc., as a comprehensive network service provider, these application products can provide users with convenient website access portals on the one hand, and on the other hand can bring more users to the website. On this basis, if you can Further providing the website access acceleration function is of great significance to both the user and the website. Of course, the present application does not need to limit the specific implementation manner of the application level.

According to S101, the proxy server can be used as the bearer of the application, and directly obtain the resource access request initiated by the user equipment to the website server, and can also obtain the user access request forwarded by other application servers.

According to S102, the proxy server needs to confirm that the user equipment has established a Socket connection with itself, and there may be two situations here:

One situation is that the Socket connection has already been established. For example, when the proxy server itself is used as the application hosting device, even if there is no need to visit the website, the Socket connection between the user device and the proxy server may be pre-established for other functions. , in this case, the established Socket connection can be maintained and further utilized to achieve subsequent website access acceleration functions;

Another situation is that the Socket connection between the user equipment and the proxy server has not yet been established. In this case, the proxy server needs to execute the operation of establishing the Socket connection.

For the specific manner of establishing a Socket connection, reference may be made to the description of the prior art, which will not be described in detail in this application.

According to S103, the proxy server obtains the corresponding target website resource according to the access request from the user side; this application provides two ways for the proxy server to obtain the target website resource:

1) Obtained locally by the proxy server.

As shown in FIG. 4 , the proxy server can obtain resource caches from other websites in advance and store them locally, and identify them in a specific way. According to S103a, after obtaining the resource access request of the user side, according to the content to be accessed, the corresponding resource is fetched from the local cache and fed back to the user side. Since the proxy server is not required to interact with the website side in real time, this method can significantly reduce the response time to the user side.

In practical applications, for products that provide relatively fixed website entrances, such as public platforms and comprehensive business service windows, the website resources corresponding to these fixed entrances can be directly pre-stored in advance, and for products such as browsers, users can Define configuration or user habits and other information to select several websites and pre-store their resources.

In addition, in order to ensure the timeliness of the locally pre-stored resources of the proxy server, the website resources stored locally on the proxy server may be updated according to a certain strategy. For example, periodically update, or actively monitor the website side and update after discovering changes in the content of website resources. If you have a relatively close cooperative relationship with the website side, you can also update according to the reminder sent by the website side. Of course, the present application does not need to limit the specific update mechanism.

2) Obtain from the website server in real time.

Referring to S103b in FIG. 5 , after obtaining the access request from the user side for the target website, the proxy server establishes a connection with the target website server in real time, and obtains resources from the target website server;

Compared with method 1), this resource acquisition method takes longer to respond to the request from the user side, but can better ensure the timeliness of resources. Moreover, for some real-time interaction requirements, such as authentication, authorization, etc., it is also necessary to obtain resources in real time.

In a specific implementation manner provided by the present application, the method of pre-storing the domain name resolution result in the proxy server may be used to further reduce the time overhead caused by the real-time interaction between the proxy server and the website server.

According to the usage habits of general users, the website domain name is used to access website resources. Even if the third-party application provides users with quick access to the website, the URL corresponding to the background is mostly based on the information stored in the website domain name. Therefore, when the proxy server establishes a connection with the target website server according to the user's request, the operation of resolving the website domain name into an IP address will take a certain amount of time. Aiming at this problem, the solution provided by this application is: store the domain name resolution result of the website (i.e. the IP address of the website) locally in the proxy server in advance, and when the proxy server needs to establish a connection with the website server, directly use the IP address of the website to communicate with the website The server establishes a connection, thereby avoiding the interaction delay caused by domain name resolution.

In practical applications, the proxy server can obtain the domain name resolution result of the website from a dedicated domain name resolution server, and can also implement the domain name resolution operation locally on the proxy server. In the portal application, the URL corresponding to the website quick access portal provided for the user may be directly saved as an IP address.

Similar to the pre-stored website resources, the proxy server can selectively save the IP addresses corresponding to some website URLs according to actual application requirements. At the same time, in order to ensure the correctness of the domain name resolution result, the domain name resolution result stored locally in the proxy server can also be updated according to a certain strategy.

The above provides two methods for the proxy server to obtain the resources of the target website, among which method 1) is more suitable for the acquisition of relatively static resources such as pictures, audio and video files, and method 2) is more suitable for scenarios that require dynamic interaction such as verification and authorization. . In practical applications, the two methods can often be used in combination, that is, for a user's access request, according to actual needs, some resources can be obtained locally from the proxy server, and other resources can be obtained from the website server in real time. . In fact, in the process of data transmission, resources such as pictures, audio and video files need to occupy most of the transmission bandwidth. Therefore, this combined resource acquisition method cannot completely avoid the delay caused by the interaction between the proxy server and the website server. When , it can still effectively reduce the amount of transmitted data between the proxy server and the website server, thereby improving the response rate of the proxy server to the user side.

In S104, the proxy server uses the established Socket connection to feed back the obtained target website resources to the user equipment, so as to respond to the access request from the user side.

In a preferred implementation manner of the present application, the proxy server may compress the resources obtained from the website server before providing them to the user side. In practical applications, the resources provided by many websites can be compressed without affecting the actual use of users to reduce the amount of data transmission between the proxy server and the user's device, thereby further reducing the transmission delay. This method is of great significance for user equipment with limited access bandwidth (such as mobile phones using wireless mobile access to the Internet), and can also reduce the data traffic of the user equipment. The compression processing operation can be completed in advance with respect to the locally pre-stored resources of the proxy server. If the benefit brought by the compression processing operation is greater than the time consumed, it can also be completed before feeding back to the user equipment. The present application does not need to limit the specific compression objects and compression algorithms, and those skilled in the art can flexibly select them according to actual needs.

It can be seen that the website access acceleration solution provided by this application improves the speed of user access to the website through multiple links such as establishing a Socket connection, pre-storing website resources in the proxy server, pre-storing website domain name analysis results, and compressing and transmitting website resources. Compared with existing acceleration solutions, the proxy server in this application does not simply play the role of resource forwarding and network interconnection, so it can obtain more obvious acceleration effects in more application scenarios. Of course, there is no conflict between the acceleration scheme of the present application and the existing acceleration scheme itself, and those skilled in the art can combine the scheme of the present application with the existing technical scheme according to actual needs.
