Abstract: A computer server program is disclosed that can execute object code provided by one or more clients even though the server was not previously programmed to execute specific code. The server executes the client code without re-compiling or re-linking. Clients provide the server with executable object code along with information about the code that allows the server to register the code object. By manipulating the registration information stored on the server, the clients can make various requests of the server which affect the execution of the code. Using the registration and request functions of the server, clients direct the server when, if, and how often to run object code or parts of object code called functions.
