URI directory service agent model for WWW intelligent service

In this paper Directory Service Agent model is proposed and implemented which is based on the client/server model. The proposed model can be provided to the transparent service for the dynamic change in the client resource access. And the information of the modified resources position has the consistency, and the updated navigation information is to be provided to users. Therefore the unnecessary HTTP (Hyper Text Transfer Protocol) message traffic can be prevented previously, and the unnecessary overhead in server and network can be gone and the quality of service can be enhanced.
