1. A system for configuring a network device with user-defined instruction scripts, the system comprising: a servicing node, comprising: at least one user-defined object; a first processor; and a first memory coupled to the first processor, the first memory storing instructions executable by the first processor; and an object virtual machine; the servicing node being configured to: receive a request for a network session between a client device and a server; receive a user-defined class with a license and a user-defined object configuration, wherein the user-defined class with the license and the user-defined object configuration includes the user-defined instruction scripts provided by a user of the network device to the servicing node; instruct the object virtual machine to generate at least one user-defined object based on the user-defined class and the user defined object configuration, the at least one user defined object including one or more parameters to enable the user-defined instruction scripts to be executed by the object virtual machine; and apply, using the object virtual machine, the at least one user-defined object to a data packet of the network session; the object virtual machine being configured to: determine, based on the license, whether the servicing node is licensed to use the user-defined class; and based on the determining that the servicing node is licensed to use the user-defined class with the license, generate, on the servicing node, the at least one user-defined object in response to the instructing, the at least one user defined object being executed and stored at the servicing node to configure the servicing node to execute the user-defined instruction scripts; and at least one node controller comprising: a second processor; and a second memory coupled to the second processor, the second memory storing instructions executable by the first processor to send the user-defined class with the license and the user-defined object configuration to the servicing node.
