This paper investigates the issues of placement of limited number of web proxies in the environment where the web server is replicated (i.e., mirrored web servers). Two different objectives are considered: minimizing the overall access cost by all clients to the web server and minimizing the longest delay for any client to access the web server. The problems are formulated and solved by using dynamic programming method. This work can: 1) alleviate the Internet traffic incurred by the fast growing web accesses; 2) improve the response time of web server accesses; 3) maximize web server performance by using limited number of proxies.
