Abstract
A method and system for invoking by a client computer system of a function of an object of an object class provided by a server computer system. The client sends a request to a server that comprises a Universal Resource Locator (“URL”) that identifies a script, an object class, and a function of the object class to invoke. In response to receiving the request, the server starts the script and transfers control to the script. The script instantiates an object of the object class identified in the URL of the received request and invokes the function identified in the URL of the received request. The invoked function performs the behavior of the function, creates a response to be sent to the client, and sends the response to the client. The response contains state information describing a state of the object after the behavior of the function is performed. When the client subsequently sends a request to invoke a function of the object class, the state information is included in the request so that the function can perform its behavior based on the state information.
