we show how we have used theseprotocols in the design of a new Resource Migration Protocol(RMP), which enables transparent resource migration acrossstandard web servers. The RMP works with a new resourcemigration mechanism we have developed called the ResourceLocator Service (RLS), and is fully backwards compatible withthe web’s architecture, enabling all web servers and all webcontent to be involved in the migration process
