The desktop-centric design of most of the current web contents pose many difficulties for pervasive browsing. In this paper, we present our study on the problem to support pervasive browsing in the heterogeneous environment of today’s Internet. A system solution – Adaptive Web Content Delivery (AWCD), is presented to overcome the problems existed in present web infrastructure. The system designed is extensible for the further development of Internet. The two major subsystems of AWCD, client profile learning and adaptation, are described in detail. Experiment results of our system are also shown.
