Abstract

Systems and methods for establishing a control channel between a virtualization server and a client device are provided. A virtual desktop session is established between the virtualization server and the client, and the virtualization server executes a virtual desktop instance. The client device executes a first application that is configured to receive a control channel connection request from a second application running within the virtual desktop instance. The second application runs an algorithm to discover an Internet Protocol (IP) address of the client device being used to access the second application. Using the IP address, a control channel outside of the virtual desktop session is established between the first and second applications. Instructions are transmitted from the second application to the first application via the control channel, and the first application is controlled remotely by the second application based on the instructions.
