A cache refresh system and cache refresh method based on http protocol

Abstract

The invention relates to a system for refreshing caches on the basis of an HTTP (hypertext transfer protocol). The system is communicated with at least one host monitor, and comprises a host information table module, a host display page module, a cache scheduler, a refreshing monitor and a cache information table module; the host information table module is used for storing URLs (uniform resource locators) of all the host monitors and comprises host IPs (internet protocols) and refreshing ports corresponding to the host IPs; the host display page module is used for reading the URLs of the host monitors and displaying the host IPs and the refreshing ports corresponding to the host IPs to a user; the cache scheduler is used for analyzing the certain host IP selected by the user and the refreshing port corresponding to the certain host IP to form HTTP information, and then transmits the HTTP information to the refreshing monitor; the refreshing monitor is used for calling the HTTP information transmitted by the cache scheduler and reading HTTP information, which is processed by the corresponding port, in the cache information table module; and the cache information table module is used for storing all refreshable ports. The system has the advantage that the caches can be remotely refreshed in real time in a batch manner.

Description

technical field [0001] The invention relates to the technical field of cache processing, in particular to a cache refresh system and a cache refresh method based on the HTTP protocol. Background technique [0002] At present, most applications use caching technology for performance considerations. Generally, when the system starts, some commonly used data is read from data sources such as configuration files and cached. If the original data is modified, it needs to be refreshed. cache. [0003] By investigating various channels, we can learn that there are two main ways to refresh the existing cache: [0004] 1. Timing refresh, which uses the apache-configuration framework, which provides a FileChangedReloadingStrategy timing refresh scheme, that is, checking the configuration file modification date at regular intervals. The disadvantages are: 1. The refresh interval is not easy to control. If the setting is too small, it will consume a lot of useless system; if the settin...
