The World Wide Web (WWW) has gained tremendously in popularity over the last several
years. Solutions to the problem of overloaded web servers have included buying more hardware,
the use of transparent server replication and mirroring, and caching of hot pages. Another
technique that can be used in conjunction with these other solutions is the use of multicast for
the delivery of web pages. In this work we explore the use of UDP, best­effort multicast as a
delivery option. Reliability is achieved through repetitive, cyclic transmission of a requested
page. This solution is expected to be most efficient when used for highly requested pages.
