Abstract

The present invention provides a method and a system for network caching, a Domain Name System (DNS) redirection sub-system thereof. The method includes: receiving a DNS resolution request sent from a client, parsing out a domain name carried by the DNS resolution request, and determining that the domain name is in a white list; obtaining the Internet Protocol (IP) address of the cache sub-system corresponding to the domain name, and sending the IP address of the cache sub-system to the client to enable the client to request data from the cache sub-system according to the IP address of the cache sub-system. The embodiments of the present invention can avoid the problem of network caching based on the policy route.

Description

Technical field [0001] The present invention relates to network communication technology, in particular to a network caching method and system, and a domain name system (DNS) redirection subsystem. Background technique [0002] With the development of the Internet, netizens will become more and more critical of the quality of their visits. On the one hand, they hope that the content provided by the website will become more and more abundant, and on the other hand, they hope that the speed of visiting the website will become faster and faster. Since the network architecture of the web server is a point-to-multipoint transmission, the network transmission contains a lot of duplicate content, and more than 80% of users frequently access 20% of the content, so caching is the best solution to the above problems Program. The Cache solution is to cache the content frequently accessed by users on the cache server, and the cache server provides services to the user without occupying the ...
