Like the caching proxy server, this proxy prefetches and stores referenced pages. It also shares the result of the prefetching among clients. The interactive prefetching scheme The WWW can be considered to be a page-oriented service. In interactions of the WWW, the client requests HTML resource and in-line images and displays them as a formatted page. The prefetching system should act in a page-oriented manner.
Users click highlighted text on the page.
This means that many requests are to retrieve referenced resources, so prefetching of referenced pages makes for faster retrieval at the client site. Therefore, our prefetching scheme is designed to get these referenced pages. The prefetching is not a recursive copying of all resources. For example, If page A of Figure 2 is retrieved, the prefetching system collects page B and C . List 1 shows a fundamental algorithm of this scheme.
