Content refreshing system

Abstract

The invention discloses a content refreshing system, which comprises a central task server and a plurality of proxy refreshing servers, wherein the central task server is used for receiving tasks submitted by a user, processing the tasks according to system configuration and transmitting the processed tasks to the proxy refreshing servers in a multi-threading way; and the proxy refreshing server is used for refreshing the tasks transmitted by the central task server and feeding an operating result back to the central task server. In the content refreshing system provided by the embodiment of the invention, the proxy refreshing server is used as a task refreshing main body, so that the problem that cache contents cannot be refreshed in time due to a plurality of situations such as over high load pressure and the like of a local server is solved, and real-time refreshing of the cache contents is realized effectively.

Description

technical field [0001] This application relates to the field of network applications, in particular to a content refreshing system. Background technique [0002] The content refresh system is one of the necessary support systems for the business and operation support system of the CDN (content delivery network, content distribution network) service provider; most of the acceleration services in the CDN service are formed in the form of cache (high-speed buffer memory) , so the content refresh system is very important for updating the cache content. [0003] Traditional content refresh generally adopts the following three methods: [0004] 1. Use the method of logging in to the server to run local commands on the server to refresh the content; in this way, when there are many servers and a lot of refreshed content, or when the content directory needs to be refreshed, the pressure on the central task server will increase, because through SSH (secure shell, a security protoco...

Problems solved by technology

[0005] 2. Set up a timing service on the refresh device to clear all caches on the machine regularly. The biggest problem with this is that the cache cannot be cleaned up in time, and there may be caches that do not need to be cleaned up.

[0006] 3. Set the cache timeout time and wait for the cache to automatically expire to clear the cache. The problem with doing this is similar to the second method. The problem is that the cache cannot be cleared in time, and the cache that does not need to be cleared may also be cleared

[0007] After studying the above three refresh methods, the inventor found that the traditional content refresh method cannot refresh the content that needs to be refreshed in time, which affects the refresh efficiency
