System and method for locating resources in a distributed network
First Claim
1. A method of finding a resource on a distributed network from a client wherein said resource has a unique resource identifier associated therewith and the client knows the resource identifier, and wherein each resource, computer, and client has a unique current logical location service process associated therewith, and wherein said resource identifier includes information regarding a birth computer and birth logical location service process of said resource, said method comprising the steps of:
- sending a message to the birth computer of said resource to determine if said resource is controlled by said birth computer;
checking a response from said birth computer, for the case where said resource is not controlled by said birth computer, sending a message to said logical location service process associated with the client to determine if it knows who controls said resource;
checking a response from said logical location service process associated with the client;
for the case where said logical location service process associated with the client does know the identity of the computer controlling said resource, sending a message to said birth logical location service process of said resource to determine who controls said resource.

Abstract
Disclosed is a system and method for implementing a distributed network system, such as the World Wide Web, in which distributed location services are utilized and include a collection of server processes that map from resource identifiers to a resource'"'"'s controlling server. In addition, distributed location services provide an architecture for assigning resource identifiers and set of protocols for accessing server processes. The server processes are logically defined to provide a more flexible system. Each of these logical server processes are an abstraction which provides the external view of the server. The logical server processes may be implemented by different numbers of physical processes running on different machines at different points in time.
