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. |
