Too much information is no information. When the quantity of data becomes too large, users need help and tools to find their path in the information space. Nowadays, any user can browse through Terabytes of data and more. The difficulty is to find the best way among all possible documents.

In this framework, the temperature of a document or a subject reflects its current interest among a community. We propose an architecture that allows proxies not only to manage efficiently cached documents but also to exchange documents with other proxies. Furthermore, these proxies manage meta-data about their partial views of the information space. We show how such an approach fits to enhance the global efficiency of the Web both in terms of access time to relevant documents and in terms of Web content indexing, adding semantic value where raw byte arrays are often considered.
