Method of simulating network communications

A method for simulating network communication sessions is disclosed. A control engine sequences the packets using a protocol stack or by putting the packets into a sorted list. A simulation engine acquires the packets until a request packet or other initiation packet is received. The simulation engine feeds the request packet to a display engine that has the ability to treat the request packet as though the display engine itself originated the request (or initiation) packet. The simulation engine then sends the response packets relating to the request to the display engine, and the display engine uses those packets to simulate the display of the network communication session substantially in the form of the original communication.
