Abstract

In this paper, we would like to address the consistency problem for web content presentation through explicit ownership schemes when its information is retrieved and reused through the Internet. Our previous study [4] on the real-time monitoring of web content already showed that for most content distribution networks (including Content Distribution Network (CDN), replica, web mirroring, and peer-to-peer), consistency problem often arises, which results in unpredictable caching behavior, performance loss, and content presentation errors. And as the client requester, current validation schemes are not enough due to the assumption on the equivalence of the content distribution address to content ownership. Our solution covers both protocols and supports for most of the necessary functions such as validation, delegation, presentation,..., etc. that need to be done in the network.
