Provided are methods and systems for configuring a network device with user-defined instruction scripts. The method may commence with receiving a request for a network session between a client device and a server. The method may further include receiving a user-defined class and a user-defined object configuration. The user-defined class and the user-defined object configuration may include the user-defined instruction scripts provided by a user of the client device. The method may further include instructing an object virtual machine to generate at least one user-defined object based on the user-defined class and the user-defined object configuration. The method may continue with instructing an object virtual machine to generate at least one user-defined object based on the user-defined class and the user-defined object configuration.
