Embodiment

[0038] The method that Squid according to the present embodiment clears the cache file according to the directory format, the method includes:

[0039] S1, combine redis with squid, when the cache misses, convert the URL accessed by the client into the key-value correspondence between domain name and directory structure, and store it in redis;

[0040] S2, when receiving an instruction to clear a set of caches, Squid first fetches a set of eligible URLs from redis, clears them one by one, and then clears the storage information related to the target URL stored in redis.

[0041] (1) Reference figure 1 with figure 2 , step S1, specifically implemented according to the following steps:

[0042] S11, as the server, squid receives the access domain name sent by the client, combines the access control list of squid to judge whether the access domain name sent by the client meets the configuration rules of squid, if yes, then allows access, and enters S12; if not, then do not al...

Abstract

The invention discloses a squid cache file clearing method according to a catalog format. The method comprises the steps of combining redis with the squid: when a cache misses, converting a URL accessed by a client to a key-value corresponding relation of a domain name-catalog structure, and storing in the redis; when a command of clearing any group of caches is received, the squid first catching a group of URLs that meet requirements in the redis, clearing one by one, then clearing related storage information of the group stored in the redis that meet the requirements. As for the scence of squid cache clearing, high performance memory server like the redis is used in the method, which not only has high performance, but also can improve the safety of data by configuration. When clearing the caches of the catalog, the method does not need to stop and clear, users access without perception, and the operation personnel basically have no learning cost.

Description

technical field [0001] The invention relates to the field of computer software, in particular to a method for Squid to clear cache files according to the directory format. Background technique [0002] Squid is a popular open source software with a wide range of uses and is often used as a cache server. When a user wants to access the web and download data, the user computer sends an application to Squid, and Squid connects to the applied website and requests the data, and then transfers the data to the user while keeping a backup. When other users apply for the same data, Squid immediately transfers the saved backup to the user, saving the back-end request link, resulting in faster response and better user experience. [0003] But when users complain about always receiving outdated data (cache), or a certain cache of Squid needs to be updated and modified, it needs to be solved by clearing the cache. [0004] However, when you want to clear the cache under the same direct...
