Abstract:
This work addresses three problems that are associated with
Web browsing:
(a) low bandwidth available to the end user who is connected
via slow modems or outdoor wireless networks,
(b) long and variable latencies in document access, and
(c) temporary disconnections of mobile users.
Three techniques are used with a variety of heuristics in order
to overcome these problems:
(a) profiling user and group access patterns and using these
profiles in order to pre-fetch documents,
(b) filtering HTTP requests and responses in order to reduce data
transmission over bottleneck links, and
(c) hoarding documents based on user profiles in order to support
limited web browsing even during disconnection.
In this paper, we describe the design and implementation of a WWW
proxy-based system that incorporates the above techniques. We
describe our experiences with the proxy system, and present
performance results that show an improvement in the
experience of Web browsing using this system.
