System and method are described for dynamically switching redirection of features between a first and a second virtual desktop that are accessed by a client in nested mode. To connect to the desktops in the nested configuration, the client can establish a first session on the first virtual desktop and then establish a session on the second virtual desktop within the first desktop. A connection can be established between the client and an agent in the first desktop for exchanging feature redirection data corresponding to a feature such as USB, clipboard, etc., and the feature can subsequently be redirected to the first desktop by exchanging corresponding data over the connection. A request can be received to switch the feature redirection to the second desktop. In response to the request, the client can establish a connection for redirecting the feature with an agent in the second desktop and the feature can be subsequently redirected to the second desktop by exchanging corresponding data over the new connection. As a result, feature redirection can be switched between desktops dynamically without terminating either virtual desktop session.
