specific Embodiment

[0044] refer to Figure 4 , a specific embodiment of the filtering caching method of the present invention is as follows:

[0045] 1. WEB Server receives user (access query) request;

[0046]2. The filter of the WEB Server intercepts the request, takes out the URL of the request, uses the URL as the key as a hash code, and modulo the number of cache servers to obtain the remainder, which is the index of the selected cache server;

[0047] 3. The filter uses the URL as the key to query from the selected cache server, and if found, returns it to the user directly;

[0048] 4. If not found in step 3, the business logic will be executed, the business logic will query the database, and use the URL as the key, output the page content as the value, write it to the selected cache server, and output it to the user.

[0049] In the caching technology of the present invention, by using the key as a hashcode, and then modulo-dividing the number of servers, the remainder obtained is the ...

Abstract

The invention discloses a filter cache method and a filter cache device, and a cache system. The filter cache method comprises the following steps of: 1, acquiring a key in a user request according to the user request; 2, selecting a cache server corresponding to the user request according to the key; and 3, querying data requested by a user from the selected cache server, and directly returning the searched data to the user. The filter cache method can improve the cache data hit rate and the cache expansibility.

Description

technical field [0001] The invention relates to the field of Internet data cache, in particular to a filtering cache method, device and cache system. Background technique [0002] In the field of Internet applications, data caching technology is very important, especially page data caching technology, not only to ensure the simplicity of caching, but also to ensure the performance and scalability of caching. Internet caching technology is generally implemented through reverse proxy. Such as figure 1 , in the reverse proxy mode, the proxy server accepts the connection request on the Internet, then forwards the request to the WEB server, and returns the result obtained from the WEB server to the client requesting the connection on the Internet. Provide services to the Internet and shield the WEB server. If the reverse proxy server finds that there is locally cached data content and it has not expired, it will no longer request the WEB server of the internal network, and ret...
