In the current server system architecture over web, one of the most important concerns is to handle load coming to Web Server dynamically, so that the server has to enable its Web sites service without any delay or failure or shutdown . Therefore, there is fundamental need to develop technology for dynamic load balancing on web side. In this study, the agent is designed on dispatcher in a Web Server cluster and implemented to distribute load dynamically by considering information related to load coming to the Web Server, especially the connection to the Map Server. Moreover, the experimental result shows that our system architecture has less traffic for Web-GIS services comparing previous architecture. Finally, agent implemented on dispatcher will select the web server in cluster, which has the lowest traffic.
