Data caching method and system for network request

Abstract

The invention relates to a data caching method and system for a network request, and the method comprises the steps: adding a data caching device between a client and a server, and receiving data request information which is transmitted on a network and has a URL identifier; the caching device intercepts and caches the URL identifier of each piece of data request information and establishes a caching database; when the client sends a data request to the server, the client sends data request information to the data caching device for judgment: when the URL identifier corresponding to the current data request information sent by the client is located in the caching database, the data caching device sends cached response data corresponding to the current URL identifier to the client; otherwise, the data caching device forwards the data request information sent by the client to the server; the server sends response data corresponding to the data request information URL identifier to the data caching device for caching; and the data caching device sends the cached corresponding response data to the client, so that the client can receive the requested data.

Description

technical field [0001] The invention relates to the network field, in particular to a data cache method and a data cache system for network requests. Background technique [0002] With the development of information network technology, various clients for different applications have been developed one after another. In order to improve the performance of the client, a data cache layer is usually added to the client or a data layer is added to the server. These clients pre-fetch data from the server and save it in memory; when the client sends a data request, the client retrieves the data from the data cache and returns the corresponding data to the client. [0003] Of course, the traditional data caching method for the above data caching mainly adopts a pre-batch data caching method for data and a real-time filling data caching method for data. For example, when the pre-batch data cache method is used, before the client starts to request data, the data cache will be filled...

Problems solved by technology

[0004] However, there are still some shortcomings in the above two traditional data caching methods: the pre-batch data caching method is actually a blind data caching. When the client needs to request a large amount of data, the data caching cannot save all the data In the memory, and it will also occupy a large amount of memory space; when the real-time filling data cache method is used, the first data request for the client will consume a lot of response time, causing the delay of the data requested by the client, and it is difficult to meet the data obtained by the client. real-time data
