Abstract

Methods and apparatus for obtaining web content are disclosed. The method includes identifying resources identified by domain name references that a user may request, obtaining a status of at least one operating condition that affects operations of the communication device, fetching, in advance of the user requesting the content, network addresses of the resources so as to resolve the domain name references, and adapting a level of the fetching based upon the at least one operating condition. The network addresses of the resources are cached so as to generate cached network addresses, and if the user requests the content, the cached network addresses are utilized to access the resources associated with the content.
