A client computer initiates a first communication session at a first network address and receives therefrom a second network address. The client computer then initiates a second communication session at the second network address and receives therefrom an access configuration including a control setting for a communication protocol capable of being utilized during a third communication session. Concurrent with the second communication session, the client computer initiates a third communication session at a third network address whereupon the conveyance of data to or from an instantiated process on the client computer via the third communication session is controlled based on the control setting for the communication protocol.
