Techniques for establishing a network connection with a client device and responding to composite requests from the client device. For a composite request identifying a first action associated with a first data plugin component and a second action associated with a different second data plugin component, the first action is performed by executing a first portion of the data plugin component and transmitting corresponding response data in a first transmission to the client device via the network connection, and the second action is performed by executing a second portion of the data plugin component and transmitting corresponding response data in a second transmission separate from the first transmission to the client device via the network connection.
