A method and apparatus for web-based tool management are implemented. A tool object model provides a logical representation of the physical tool. The tool object model defines a hierarchical set of tool objects that characterize the tool, and additionally a set of method for performing actions on the tool objects. These actions also correspond to operations, which may include reporting as well as processing tasks, performed by the tool. A user may remotely control and monitor a tool using a conventional web browser. For example, a user may execute methods of the tool object model, or obtain detailed information about a tool object. User actions are passed to a server by embedding them in hypertext transfer protocol (HTTP) requests. The server receives the HTTP request, and passes the request to a corresponding page server in accordance with the action requested. Depending on the action requested, the page server may generate a web page in response, or may invoke a method of the tool object model.
