Background technique

At present, network acceleration technology has become a hot technology. The core focus of technology is how to reduce network bandwidth and provide users with normal web access. In terms of accessing http static resources, the current main method is to deploy a proxy server, obtain a user request resource from a source station through a proxy server, and the proxy server caches the resource and provides user service. When the user accesses the cache resource again, the proxy server provides the user service of the resource, and no longer needs to obtain the requested resource from the source station, thereby reducing the number of times the same resource is acquired from the source station, thereby saving the network bandwidth between the proxy server and the source station.

However, the resources cached by the general proxy server are time-limited. The time limit is usually determined by the source station. When the user accesses the time-efficient cache resource, the user's access to the resource is again obtained from the source station. However, the resource may not be updated or may have been updated. For the unupdated resource, if it is obtained again from the source station, it will occupy the bandwidth resource between the proxy server and the source station.

In view of the problem of large bandwidth resource consumption between the proxy server and the source station in the related art, an effective solution has not been proposed yet.

Cache processing device.

The invention will now be described in detail in conjunction with alternative embodiments and embodiments.

In this alternative embodiment, the proxy server can also use the cached unupdated overdue resources. Providing services to reduce bandwidth consumption between the proxy server and the source station, the basic idea of this alternative embodiment is as follows:

While the proxy server caches the accessed http static resource, the source station returns the detection information that may exist in the http response message for detecting whether the resource is updated, such as last_modify, etag. When the same resource is accessed again through the proxy server, and the resource has expired, 304 termination is set on the proxy server side, and the saved information for detecting whether the resource is updated is sent back to the source station, such as the source station. Update, return the status code 200 and the updated resource to the proxy server, and provide the updated resource to the user terminal; otherwise, return the status code 304 to the proxy server. Since the proxy server side sets the 304 termination, the proxy server will directly serve the user. The terminal provides services, and the proxy server provides services for the user terminal by using the expired resources that have been cached by the proxy server.

This alternative embodiment is achieved by the following technical means.

The proxy server is deployed in the network acceleration system, and the http static resource requested by the user terminal is obtained from the source station through the proxy server, and the proxy server caches the accessed http static resource to provide cache access.

When the proxy server receives the response of the http static resource request, it saves the information in the response message for detecting whether the resource is updated, such as last_modify, etag, etc., and the saved information must be guaranteed to be quickly retrieved, so it is better to save it in the memory.

When the http static resource cached by the proxy server is again accessed by the user terminal, the proxy server determines whether the resource is expired. If not expired, the proxy server caches the hit, and the proxy server uses the cached content to provide services for the user; if the resource expires, the setting 304 ends. And retrieving the saved information for detecting whether the resource is updated, assembling a new http access request, and transmitting it to the source station.

The source station receives an http static resource access request for detecting whether the user terminal access resource is updated, and determines whether the resource is updated. If the resource has been updated, the 200 status code and the updated resource are sent to the proxy server, and the proxy server The user terminal provides the service and caches the updated content; if the resource is not updated, the 304 status code is returned to the proxy server, and the detailed content is not sent. Since the 304 termination is set, the user terminal requests access to be served by the proxy server, and the proxy server uses The cached overdue resources provide services.

FIG. 5 is a schematic diagram of a flow of a proxy server user terminal accessing a http static resource system according to a preferred embodiment of the present invention. As shown in FIG. 5, in the present diagram, the user terminal 1 and the user terminal 2 are used. Each of the user terminals 3 specifically refers to a type of user terminal.

S1001, the user terminal 1, may specifically refer to the user terminal that accesses the http static resource for the first time, and initiates a http static resource access request to the proxy server.

S1002: The proxy server forwards the http static resource access request to the source station.

S1003, the source station responds to the http access request.

S1004: The proxy server saves related information (ie, the above-mentioned update detection information) for determining whether the resource is updated to the memory area.

S1005. The proxy server provides the service to the user terminal by using the resource content provided by the source station.

S1006, the user terminal 2, may specifically refer to the user terminal that accesses the resource in the case that the proxy server cache resource does not expire, and initiates the same http static resource request to the proxy server.

S1007. Detecting that the proxy server determines that the cache resource does not expire.

S1008, directly using the proxy server cache to provide services, that is, cache hits.

S1009, the user terminal 3, may specifically refer to the user terminal that accesses the resource in the case that the proxy server caches the resource expires, and initiates the same http static request to the proxy server.

S1010: It is detected that the proxy server detects that the resource is out of date.

S1011: Set 304 to terminate, and retrieve related information for determining whether the resource content is updated corresponding to the http request resource, reassemble the http access request, and carry relevant information for determining whether the resource content is updated, and send the information to the source station.

S1012: Determine whether the resource is updated. If the resource of the http access request is updated, return a status code of 200 and new content to the proxy server; if the resource of the http access request is not updated, return a status code of 304 to the proxy server and does not include the detailed content. .

S1013, responding to the request of the proxy server.

S1014: The proxy server returns the information according to the source station, and the content update provides the service for the user terminal by using the new resource content, and the resource is updated; otherwise, the proxy server provides the service for the user terminal by using the expired resource content that the server itself has cached.

S1015, responding to http access.

In this alternative embodiment, the core of network acceleration is to interact with the source station as little as possible, and to provide user services through the proxy server cache, which has been able to reduce network bandwidth consumption. In order to reduce the bandwidth used again, if the user terminal accesses the cached unupdated expired resource, if there is a way to detect that the source station is not updated, the cached resource content is used to serve the user terminal. It is also possible to further reduce the bandwidth used. In view of the need for rapid response of network resource access, it is necessary to save information for detecting whether the resource content is updated, and it is necessary to save it to the high-speed device to enable quick access, in order to use less information to obtain the information. Time overhead, reducing the network bandwidth consumption caused by the return source.
