Adaptation-Aware Web Caching: Caching in the Future Pervasive Web

In the upcoming world of Pervasive Computing, content adaptation is an essential concept to meet the heterogeneous requirements of web users using various web access technologies. However, content adaptation interferes with the effectiveness of web caching. Leveraging the advantages of web caching even in the world of Pervasive Computing is the subject of this paper. We present an approach that joins the concepts of web caching and content adaptation in a uniform scheme. We have conceived an architecture of hierarchical, independent caching proxies that are aware of the heterogeneous capabilities of the client population. Content adaptation is performed by adaptation services on behalf of the proxies. By this means, the proxies merge their local cache management with the composition of a distributed adaptation path and avoid the interference between content adaptation and web caching.
