But a considerable part of the tremendous information in the internet is digital works which are entitled to copyright. The process of operating the "web cache" is suspected of direct invasion to the exclusive rights of the digital works. So how should we deal with the technology which should be neutral originally? There are lots of controversies in academic and practical world both in China and aboard.In the case "Field v.
