Abstract
A method of caching web content, performed by a network node such as a caching proxy, is disclosed. The method comprises receiving, from a client, a Domain Name System (DNS) resolution request comprising a hostname. The DNS resolution request is forwarded to a DNS server. A DNS resolution response comprising an Internet Protocol (IP) address corresponding to the hostname is received from the DNS server. The DNS resolution response is forwarded to the client. The method further comprises determining if the DNS resolution request relates to a web session, and if so, retrieving an index page from a web server associated with the received IP address, and caching the retrieved index page. Thereby, a subsequent initial Hyper Text Transfer Protocol (HTTP) request from the client for that index page can be accelerated.
